Essay on How To Prevent Dengue

Students are often asked to write an essay on How To Prevent Dengue in their schools and colleges. And if you’re also looking for the same, we have created 100-word, 250-word, and 500-word essays on the topic.

Let’s take a look…

100 Words Essay on How To Prevent Dengue

Understanding dengue.

Dengue is a sickness spread by mosquitoes. When an infected mosquito bites a person, they can get dengue. It can make people feel very sick. To stop dengue, we need to stop these mosquitoes.

Stopping Mosquitoes

To prevent dengue, keep mosquitoes away. Make sure water doesn’t collect in places like flower pots or buckets because mosquitoes lay eggs in water. Use screens on windows and doors.

Protect Yourself

Wear long sleeves and pants to cover your skin. Use mosquito repellent on your body. These steps will help keep mosquitoes from biting you.

Throw away trash and clean places where water can stand. A clean environment will discourage mosquito breeding. Always remember, no mosquitoes mean no dengue.

250 Words Essay on How To Prevent Dengue

Dengue is a sickness spread by mosquitoes. These mosquitoes bite during the day, especially early in the morning or before it gets dark. When they bite someone who is sick with dengue, they can then spread it to other people. To stop dengue, we need to stop these mosquitoes.

Keep Water Clean

Mosquitoes that spread dengue love to lay their eggs in water that does not move, like in buckets, bowls, or pots. It’s important to keep these containers empty or covered so mosquitoes cannot use them. If you have things like flower vases or pet water bowls, change the water every day.

Stay Safe Inside

To keep mosquitoes away, use screens on windows and doors. If you don’t have screens, try to use mosquito nets over your bed when you sleep. You can also use air conditioning because mosquitoes do not like cold places.

When you go outside, wear clothes that cover your arms and legs. Use mosquito repellent on your skin that is safe and works well. Sprays or creams can be good choices.

Mosquitoes can hide and lay eggs in tall grass and trash. Keep your yard and places near your home clean. Throw away trash like cans or bottles where water can collect.

Remember, stopping dengue starts with each of us. By keeping our homes and neighborhoods clean and using protection like nets and repellents, we can fight against dengue together.

500 Words Essay on How To Prevent Dengue

Dengue is a sickness spread by mosquitoes, tiny insects that bite humans and animals. When a mosquito bites a person who has dengue, it can pick up the virus and then spread it to others. This illness can make people feel very sick, with high fever, pain in their muscles, headaches, and a rash. To avoid getting dengue, we need to stop these mosquitoes from biting us and from breeding.

Stopping Mosquitoes from Breeding

Mosquitoes lay eggs in water, so the first step in preventing dengue is to get rid of any standing water around your home. This means emptying out flower pots, buckets, and barrels after it rains. If you have a water tank or a container that you can’t empty, make sure it’s covered so mosquitoes can’t get in. Clean your gutters too, so water doesn’t stand in them and give mosquitoes a place to breed.

Protecting Yourself from Bites

To keep mosquitoes from biting you, wear clothes that cover your arms and legs, especially during early morning and late afternoon, when mosquitoes are most active. Use mosquito repellent on your skin and clothes. There are special creams and sprays you can buy that help keep mosquitoes away. At night, sleep under a mosquito net, especially if you live in a place where there are lots of mosquitoes.

Keeping Mosquitoes Out of Your Home

Make sure your windows and doors have screens that are in good condition to stop mosquitoes from coming inside. If there are holes in the screens, fix them. Use air conditioning if you have it, as it can help keep mosquitoes outside. Mosquitoes don’t like cold, moving air.

Community Action

Fighting dengue is not just a job for one person; it’s something the whole community should do together. Talk to your neighbors about the importance of getting rid of standing water and protecting themselves from mosquito bites. Sometimes, health workers spray chemicals to kill mosquitoes in areas where there is a lot of dengue. If this happens in your area, stay inside while they’re spraying and follow any instructions they give.

Preventing dengue is important because it keeps us healthy and out of the hospital. By getting rid of standing water, protecting ourselves from mosquito bites, keeping our homes mosquito-free, and working together as a community, we can stop the spread of dengue. Remember, every small step helps, and when we all do our part, we can make a big difference. Stay safe and be proactive in the fight against dengue!

Introduction

• Dengue is the most rapidly spreading mosquito-borne viral disease in the world.
• According to the data of the World Health Organisation (WHO), an estimated 50 million dengue infections occur annually and approximately 2.5 billion people live in dengue-endemic countries.
• Dengue inflicts significant health, economic and social burden on the populations of endemic areas.
• Dengue afflicts all levels of society, but the burden may be higher among the poorest who grow up in communities with an inadequate water supply and solid waste infrastructure, and where conditions are most favourable for multiplication of the main vector, Aedes aegypti.

What are the Symptoms of Dengue Fever?

The symptoms include:

• Muscle and joint pains

It takes about two to seven days to fully recover. In extreme cases, the disease can develop into severe dengue, known as dengue hemorrhagic fever that causes bleeding, low levels of blood platelets, and blood plasma leakage.

What Causes Dengue Fever?

• Dengue is spread by several species of female mosquitoes of the Aedes variety, specifically of the Aedes aegypti.
• The ideal conditions for this species of mosquitos are usually between the latitudes of 35° North and 35° South with an elevation of 1000 meters (3300 ft). They usually bite during the early morning and in the evening, though it does not mean that they will specifically bite at these hours.
• Even though humans are the primary host of the virus, non-human primates are also carriers.
• A single bite is more than enough to be a cause for infection.
• A female mosquito that bites a person infected person with dengue becomes infected during the initial 2-10 day febrile period.
• After 8 – 10 days, the virus spreads to other tissues including the mosquitoes salivary glands, and is subsequently released into its saliva. As per the research conducted on this species, the mosquito remains infected.

The image below explains the life-cycle of dengue fever:

What can be done to prevent the spread of Dengue Fever?

The spread of Dengue fever is largely dependent on the control of and protection from the bites of the mosquito that transmits it. The following five elements are the recommendation for an Integrated Vector Control by the World Health Organisation:

• Advocacy, social mobilization, and legislation to ensure that public health bodies and communities are strengthened
• Collaboration between the health and other sectors (public and private);
• An integrated approach to disease control to maximize the use of resources;
• Evidence-based decision-making to ensure any interventions are targeted appropriately; and
• Capacity-building to ensure an adequate response to the local situation.
• The main method of controlling the breeding of Aedes aegypti is by destroying its habitats and breeding grounds the primary method of controlling Aedes aegypti is by eliminating its habitats. This involves eliminating open sources of water. This is done by getting rid of open sources of water, or by adding insecticides or biological control agents to these areas.
• The removal of open collection of water is far more effective and optimal removal of control as the application of insecticides may have adverse negative health effects on the local population, due to the risk they pose in contaminating local food sources.
• People can prevent mosquito bites by wearing clothing that fully covers the skin, using mosquito netting while resting, and/or the application of insect repellent (DEET being the most effective).
• While these measures can be an effective means of reducing an individual’s risk of exposure, they do little in terms of mitigating the frequency of outbreaks, which appear to be on the rise in some areas, probably due to urbanization increasing the habitat of Aedes aegypti .

Frequently Asked Questions Related to Dengue

How dengue is caused, how many days does it take to recover from dengue, what are the warning signs of dengue.

Warning Signs of dengue are as follows:

• Abdominal pain or tenderness.
• Persistent vomiting.

Dengue: Causes and Prevention

Last updated on November 16, 2022 by ClearIAS Team

Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes. India sees a rise in cases of dengue, especially in rainy seasons. It is one of the most rapidly spreading viral tropical diseases. Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. Read here to know the causes, symptoms, and preventive measures for dengue.

Dengue is a mosquito-borne viral disease that has rapidly spread to all tropical regions .

Dengue virus is transmitted by female mosquitoes mainly of the species  Aedes aegypti  and, to a lesser extent,  Ae. albopictus .

Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

A recent study published in 2022 projected how the distribution of these mosquitoes will evolve with climate change .

• Currently,  Aedes Aegyptus is prevalent in the southern peninsula, eastern coastline, north-eastern states, and the northern plains.
• Aedes albopictus dominates the eastern and western coastlines, north-eastern states, and the lower Himalayas.
• The study projected the expansion of Aedes aegypti in the hot arid regions of the Thar Desert and Aedes albopictus in the cold upper Himalayas as a result of future climatic changes.

Historical reference of dengue

In a Chinese medical encyclopedia from the Jin Dynasty published in 992, dengue disease was initially described as “water poison” related to flying insects (265-420 AD).

The Swahili word Ka-dinga pepo, which translates to “cramp-like seizure,” is where the English word “dengue” originates.

In the 1780s, the first dengue outbreaks to be clinically identified occurred practically concurrently in Asia, Africa, and North America.

Because of the symptoms of myalgia and arthralgia, Benjamin Rush, who popularised the term “break-bone fever,” wrote the first clinical case report of the 1780 pandemic in Philadelphia in 1789.

The term dengue fever came into general use only after 1828.

Causes and symptoms of Dengue

Dengue virus belongs to the family Flaviviridae , having four serotypes that are spread by the bite of infected Aedes mosquitoes.

• There are four dengue virus serotypes and it is possible to be infected four times.
• These mosquitoes are also vectors of chikungunya, yellow fever, and Zika viruses.
• The ideal conditions for this species of mosquitos are usually between the latitudes of 35° North and 35° South with an elevation of 1000 meters (3300 ft).
• They usually bite during the early morning and in the evening, though it does not mean that they will specifically bite at these hours.
• A single bite is more than enough to be a cause for infection.
• A female mosquito that bites an infected person with dengue becomes infected during the initial 2-10-day febrile period.
• After 8-10 days, the virus spreads to other tissues including the mosquito’s salivary glands and is subsequently released into its saliva.

It causes a wide spectrum of illnesses from mild asymptomatic illness to severe fatal dengue hemorrhagic fever/dengue shock syndrome.

Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries. Severe dengue was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand.

There is no specific treatment for dengue/severe dengue. Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%.

Dengue should be suspected when a high fever (40°C/104°F) is accompanied by two of the following symptoms during the febrile phase (2-7 days):

• severe headache
• pain behind the eyes
• muscle and joint pains
• swollen glands

Transmission of the virus

There are several routes of transmission of the dengue virus-

Transmission through the mosquito bite

The virus is transmitted to humans through the bites of infected female mosquitoes, primarily the  Aedes aegypti  mosquito.

• After feeding on a Virus-infected person, the virus replicates in the mosquito midgut, before it disseminates to secondary tissues, including the salivary glands.
• The time it takes from ingesting the virus to actual transmission to a new host is termed the extrinsic incubation period (EIP).
• The EIP takes about 8-12 days when the ambient temperature is between 25-28°C.

Human-to-mosquito transmission

• Mosquitoes can become infected by people who are viraemic with the virus. This can be someone who has a symptomatic dengue infection, someone who is yet to have a symptomatic infection (they are pre-symptomatic), but also people who show no signs of illness as well (they are asymptomatic).
• Human-to-mosquito transmission can occur up to 2 days before someone shows symptoms of the illness, up to 2 days after the fever has resolved.

Maternal transmission

• The primary mode of transmission of Viruses between humans involves mosquito vectors.
• There is evidence, however, of the possibility of maternal transmission (from a pregnant mother to her baby).
• While vertical transmission rates appear low, the risk of vertical transmission is seemingly linked to the timing of the dengue infection during pregnancy.
• When a mother does have a DENV infection when she is pregnant, babies may suffer from pre-term birth, low birth weight, and fetal distress.

Treatment and Vaccination

There is no specific treatment for viral fever. Patients should rest, stay hydrated and seek medical advice.

Supportive care such as fever reducers and painkillers can be taken to control the symptoms of muscle aches and pains, and fever.

The first dengue vaccine, Dengvaxia® (CYD-TDV) developed by Sanofi Pasteur was licensed in December 2015 and has now been approved by regulatory authorities in ~20 countries.

Global burden of dengue

The incidence of dengue has grown dramatically around the world in recent decades. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses.

The total number of cases seemingly decreased during the years 2020 and 2021, as well as for reported deaths. However, the data is not yet complete and the COVID-19 pandemic might have also hampered case reporting in several countries.

Before 1970, only 9 countries had experienced severe dengue epidemics.

• The disease is now endemic in more than 100 countries in the regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia, and the Western Pacific.
• The Americas, South-East Asia, and Western Pacific regions are the most seriously affected, with Asia representing ~70% of the global burden of disease.
• Local transmission was reported for the first time in France and Croatia in 2010 and imported cases were detected in three other European countries.

Prevention and Control of Dengue

The proximity of mosquito vector breeding sites to human habitation is a significant risk factor for dengue.

At present, the main method to control or prevent the transmission of the dengue virus is to combat the mosquito vectors. This is achieved through:

• Prevention of mosquito breeding.
• Personal protection from mosquito bites.
• Educating the community on the risks of mosquito-borne diseases.
• Active mosquito and virus surveillance.
• Vector surveillance can be combined with clinical and environmental surveillance

The integration of vector management approaches is encouraged by the WHO to achieve sustainable, effective locally adapted vector control interventions.

The government of India has a National Centre for Vector Borne diseases under the Ministry of Health, which updates guidelines and preventive measures for numerous vector-borne diseases like dengue, chikungunya, and malaria .

As you probably know, dengue fever is a potentially lethal disease that can be found in subtropical and tropical regions around the world. It affects 50 million people a year and can cause permanent harm to an infected person.

For more information, see the following facts:

• Dengue fever is transmitted by the Aedes aegypti mosquito, which also spreads such diseases as Chikungunya and yellow fever.
• The Aedes mosquito is most active today, especially around dawn and dusk. However, you should remember that this insect can bite any time of day or night.
• The first registered epidemic of dengue fever happened in 1779-1780 across Asia, Africa, and North America.
• A global pandemic of dengue fever began in Southeast Asia after World War II.
• Most dengue cases occur in urban areas.
• Infected mosquitoes pass on the virus for the rest of their lives.
• Only female mosquitoes are carriers of dengue fever.
• There are four different strains of the virus that causes dengue fever.
• There is no specific treatment for dengue fever.
• Patients who have dengue fever should never take aspirin because it can intensify the bleeding. Instead, they should take paracetamol to relieve pain.
• Between 2015 and 2016, the first dengue vaccine was licensed in several countries.
• In most cases, dengue fever symptoms include muscle pain, skin rash, fever, loss of appetite, nausea, vomiting, swollen glands, and blood vessels’ disintegration, leading to heavy bleeding.

Keep these facts in mind as you compose your essay on dengue fever. You may incorporate them in your writing or at least avoid mistakes.

After the facts and tips above, you may still be wondering about dengue essay writing. The issue is broad and multifaceted, having affected numerous people. Besides, you may be unfamiliar with the regions where it can be found.

Here are some hints on writing a dengue essay:

• Essays on dengue fever may describe the symptoms of the disease first of all. It is an infectious disease, and many people confuse it with malaria . Thus, you should present the symptoms in your writing. They are a severe headache, pain in the muscles and joints, and a rash that can be described as small red spots. Some patients experience gastritis, diarrhea, vomiting, and abdominal pain.
• You can note that the diagnosis of the disease is made clinically in most cases. Thus, if a person has the above-described symptoms, he/she must go to the hospital immediately.
• Tell about the methods of treatment in your dengue fever essay. The procedure is mostly based on supportive therapy. In cases when a patient is suspected of having melena, which is a sign of inner gastrointestinal bleeding , platelet transfusion may be necessary.
• Your dengue essay can define the methods of disease prevention. Nowadays, the most reliable way is to control the mosquitoes that transmit the disease. Scientists are also trying to invent a vaccine against dengue fever, but now the research is only in the experimental stage.

So, these are the central arguments that a student can introduce in essays on dengue. You use them all or develop your approach. Just cover the essentials and remain unbiased like in an example below:

Dengue is an acute viral illness caused by RNA virus of the family Flaviviridae and spread by Aedes mosquitoes. Presenting features may range from asymptomatic fever to dreaded complications such as hemorrhagic fever and shock. A cute-onset high fever, muscle and joint pain, myalgia, cutaneous rash, hemorrhagic episodes, and circulatory shock are the commonly seen symptoms. Oral manifestations are rare in dengue infection; however, some cases may have oral features as the only presenting manifestation. Early and accurate diagnosis is critical to reduce mortality. Although dengue virus infections are usually self-limiting, dengue infection has come up as a public health challenge in the tropical and subtropical nations. This article provide a detailed overview on dengue virus infections, varied clinical manifestations, diagnosis, differential diagnosis, and prevention and treatment.

INTRODUCTION

The dengue virus, a member of the genus Flavivirus of the family Flaviviridae, is an arthropode-borne virus that includes four different serotypes (DEN-1, DEN-2, DEN-3, and DEN-4).[ 1 , 2 ] The World Health Organization (WHO) consider dengue as a major global public health challenge in the tropic and subtropic nations. Dengue has seen a 30-fold upsurge worldwide between 1960 and 2010, due to increased population growth rate, global warming, unplanned urbanization, inefficient mosquito control, frequent air travel, and lack of health care facilities.[ 3 , 4 , 5 ] Two and a half billion people reside in dengue-endemic regions[ 5 ] and roughly 400 million infections occuring per year, with a mortality rate surpassing 5–20% in some areas.[ 6 ] Dengue infection affects more than 100 countries, including Europe and the United States (USA).[ 7 ] The first reported case of dengue like illness in india was in Madras in 1780, the first virologically proved epidemic of DF in India occurred in Calcutta and Eastern Coast of India in 1963-1964.[ 8 ] Dengue virus infection presents with a diverse clinical picture that ranges from asymptomatic illness to DF to the severe illness of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS).[ 4 ] Oral mucosal involvement is seen in approximately 30% of patients, although oral features are more frequently associated with DHF than with DF.[ 9 ] Dengue virus infection exhibit varied clinical presentation, hence, accurate diagnosis is difficult and relies on laboratory confirmation. The condition is usually self-limiting and antiviral therapy is not currently available. Supportive care with analgesics, hydration with fluid replacement, and sufficient bed rest forms the preferred management strategy.

ETIOPATHOGENESIS

DF is a severe flu-like infection that involves individuals of all age groups (infants, children, adolescents, and adults).[ 9 ] Transmission among human beings occurs by the mosquito Aedes aegypti and chiefly occurs during the rainy season.[ 10 ] The proposed etiologies for dengue virus infection are:

• Viral replication, primarily in macrophages[ 11 ]
• Direct skin infection by the virus[ 12 ]
• Immunological and chemical-mediated mechanism induced by host–viral interaction.[ 12 ]

Dengue virus gains entry into the host organism through the skin following an infected mosquito bite. Humoral, cellular, and innate host immune responses are implicated in the progression of the illness and the more severe clinical signs occur following the rapid clearance of the virus from the host organism. Hence, the most severe clinical presentation during the infection course does not correlate with a high viral load.[ 13 ] Alterations in endothelial microvascular permeability and thromboregulatory mechanisms lead to an increased loss of protein and plasma. Proposed theories suggest that endothelial cell activation caused by monocytes, T-cells, the complement system, and various inflammatory molecules mediate plasma leakage. Thrombocytopenia may be related to alterations in megakaryocytopoiesis, manifested by infection of human hematopoietic cells and compromised progenitor cell growth. This may cause platelet dysfunction, damage, or depletion, leading to significant hemorrhages.[ 14 , 15 ]

Figure 1 depicts a diagramatic representation of the pathogenesis of dengue.

Pathogenesis of dengue virus infection

CLASSIFICATION

The WHO classifies DF into two groups: Uncomplicated and severe.[ 16 , 17 ] Severe cases are linked to excessive hemorrhage, organ impairement, or severe plasma escape, and the remaining cases are considered uncomplicated.[ 17 ]

According to the 1997 classification, dengue can be divided into undifferentiated fever, DF, and DHF.[ 18 ] DHF was further subdivided into grades I–IV.

Grade I: Only mild bruising or a positive tourniquet test

Grade II: Spontaneous bleeding into the skin and elsewhere

Grade III: Clinical sign of shock

Grade IV: Severe shock - feeble pulse, and blood pressure cannot be recorded.[ 19 ]

Here, grades III and IV comprise DSS.[ 17 ]

CLINICAL MANIFESTATIONS

Undifferentiated fever.

This stage is seen mostly in the primary infection but may also occur following the initial secondary infection. Clinically, it is difficult to differentiate from numerous other viral diseases and often remains undiagnosed.

Dengue fever

DF follows both primary and secondary infections, and is most frequently encountered in adults and older children. Onset of symptoms is characterized by a biphasic, high-grade fever lasting for 3 days to 1 week.[ 20 , 21 ] Severe headache (mainly retrobulbar), lassitude, myalgia and painful joint, metallic taste, apetite loss, diarrhea, vomiting, and stomachache are the other reported manifestations. Dengue is also known as breakbone fever because of the associated myalgia and pain in joints.[ 16 , 22 ] Of patients with DF, 50–82% report with a peculiar cutaneous rash.[ 23 , 24 ] The initial rash is the result of capillary dilatation, and presents as a transient facial flushing erythema, typically occuring before or during the first 1–2 days of fever. The second rash is seen at 3 days to 1 week following the fever, and presents as a asymptomatic maculopapular or morbilliform eruption. Sometimes, individual lesions may merge and present as widespread confluent erythematous areas with pinpoint bleeding spots and rounded islands of sparing, giving a typical appearance of “white islands in a sea of red.”[ 23 , 25 ] The cutaneous rash is usually asymptomatic, and pruritis is reported only in 16-27% cases.[ 9 , 26 ] Bleeding episodes are infrequently seen in DF, although epistaxis and gingival bleeding, substantial menstruation, petechiae/purpura, and gastrointestinal tract (GIT) hemorrhage can occur.[ 20 , 27 ]

Dengue hemorrhagic fever

DHF is frequently seen during a secondary dengue infection. However, in infants it may also occur durring a primary infection due to maternally attained dengue antibodies.[ 28 ] The proposed diagnostic criteria for DHF includes:[ 29 ]

• a. Clinical parameters: Acute-onset febrile phase – high-grade fever lasting from 2 days to 1 week. Hemorrhagic episodes (at least one of the following forms): Petechiae, purpura, ecchymosis, epistaxis, gingival and mucosal bleeding, GIT or injection site, hematemesis and/or malena

Positive tourniquet and hepatomegaly.

• b. Laboratory parameters: Thrombocytopenia (platelet count <100,000/cu mm)

The hemorrhagic episodes in DHF are associated with multifactorial pathogenesis. Vasculopathy, deficiency and dysfunction of platelets and defects in the blood coagulation pathways are the attributed factors.[ 30 ] Decreased production of platelets[ 31 , 32 ] and increased destruction of platelets may result in thrombocytopenia in DHF.[ 33 ] The impaired platelet function causes the blood vessels to become fragile and this results in hemorrhage.[ 34 ]

The clinical course of DHF is characterized by three phases: Febrile, leakage, and convalescent phase. High-grade fever of acute onset along with constitutional signs and facial erythema characterizes the commencement of the febrile illness.[ 21 ] The initial febrile illness is marked by a morbilliform rash and hemorrhagic tendencies.[ 35 ] The fever persists for 2 days to 1 week and then drops to normal or subnormal levels when the patient either convalesces or advances to the plasma leakage phase.[ 36 ] High plasma escape cases are marked by frank shock with low pulse pressure, cyanosis, hepatomegaly, pleural and pericardial effusions, and ascites. Severe ecchymosis and gastrointestinal bleeding followed by epistaxis may also be noted in a few cases. Bradycardia, confluent petechial rashes, erythema, and pallor are seen during this phase.

Dengue shock syndrome

DSS is defined as DHF accompanied by a unstable pulse, narrow pulse pressure (<20 mmHg), restlessness, cold, clammy skin, and circumoral cyanosis. Progressively worsening shock, multiorgan damage, and disseminated intravascular coagulation account for a high mortality rate associated with DSS. The shock persists for a short span of time and the patient promptly recovers with supportive therapy.[ 37 , 38 ]

OROFACIAL FEATURES

Oral features are infrequently seen in dengue virus infection and are more commonly associated with DHF. Erythema, crusting of lips, and ntongue and soft palatal vesicles constitute the prominent oral features in dengue virus infection. Chadwick et al .[ 26 ] reported higher cases involving the mucosa with scleral injection (90%), whereas Sanford noticed vesicular eruptions of the soft palate (>50%).[ 39 ] Byatnal et al ., reported numerous hemorrhagic bullae on the sublingual mucous membrane, lateral surface of the tongue, and floor of the mouth. Brown-colored plaquelike lesions with a rough surface were seen on the buccal mucosa that showed bleeding on touch along with spontaneous bleeding from the gingiva and the tongue. Petechiae, purpura, ecchymoses, and nasal bleeding have also been reported.[ 40 ] Mitra et al . reported bleeding gums, hemorrhagic plaques, and inflamed tonsils in a dengue-infected patient.[ 41 ] Isolated hypoglossal nerve palsy following dengue infection is a rare occurence.[ 42 ] Taste alteration, conjunctival redness, and lymphadenopathy may also be reported in DF.[ 3 ] Table 1 depicts the reported orofacial features of dengue.

Summary of reported orofacial features in dengue[ 4 ]

Cautious attention should be directed at DF if a patient suffers from high fever within 2 weeks of being in the tropics or subtropics.[ 43 ] A decreased number of white blood cells (leukopenia), accompanied by a decreased number of platelet count (thrombocytopenia) and metabolic acidosis are the initial changes on laboratory examinations. Microbiological laboratory testing confirms the diagnosis of DF. Virus segregation in cell cultures, nucleic acid demonstration by polymerase chain reaction (PCR), and serological detection of viral antigens (such as NS1) or particular antibodies are the preferred microbiological assays.[ 5 ] Viral segregation and nucleic acid demonstration provide precise diagnosis, although the high cost limits the availability of these tests.

DIFFERENTIAL DIAGNOSIS

Broad differential diagnosis is considered in a patient presenting with fever and a rash similar to that seen in DF. Tables ​ Tables2 2 and ​ and3 3 present the varied clinical conditions that mimic the febrile and critical phase of dengue infection.

Conditions that mimic the febrile phase of dengue infection[ 4 ]

Conditions that mimic the critical phase of dengue infection[ 4 ]

MANAGEMENT OF DENGUE INFECTION

Fluid replacement and antipyretic therapy with paracetamol is the preferred therapy following the febrile phase. Care should be taken not to use other nonsteroidal antiinflammatory drugs.

Judicious fluid administration forms the mainstay of treatment during the critical phase of the infection. Normal saline, Ringer's Lactate, and 5% glucose diluted 1:2 or 1:1 in normal saline, plasma, plasma substitutes, or 5% albumin are the routinely administered fluids.

WHO guidelines summarize the following principles of fluid therapy:[ 44 ]

• Oral fluid supplementation must be as plentiful as possible. However, intravenous fluid administration is mandatory in cases of shock, severe vomiting, and prostration (cases where the patient is unable to take fluids orally)
• Crystalloids form the first-line choice of intravenous fluid (0.9% saline)
• Hypotensive states that are unresponsive to boluses of intravenous crystalloids, colloids (e.g., dextran) form the second-line measures
• If the patient remains in the critical phase with low platelet counts, there should be a serious concern for bleeding. Suspected cases of bleeding are best managed by transfusion of fresh whole blood.

DENTAL MANAGEMENT

Oral lesions are infrequently seen and are often misguided as platelet defects.[ 25 ] Significant hemorrhagic manifestations need platelet transfusions. In general, there is no need to give prophylactic platelets even at <20,000/cu mm. Prophylactic platelets may be given at a level of <10,000/cu mm in absence of bleeding manifestations. In case of systemic massive bleeding, platelet transfusion may be needed along with red cell transfusion. Liver functions should be monitored.

ADVANCED RESEARCHES

Control of mosquito (vector) transmission, development of dengue vaccine, and antiviral drugs constitute future directions with an aim to prevent and treat dengue infection.

Control of mosquito (vector) transmission can be done by keeping guppies ( Poecilia reticulata ) or copepods ( doridicola agilis ) in standing water, and infecting the mosquito population with bacteria of the Wolbachia genus.[ 43 ]

Due to the progressing transmission and enhancing severity of dengue infection, the necessity to develop a dengue vaccine has gained considerable importance. There is a worldwide public health need for a safe, effective, and economic tetravalent dengue vaccine. Complex pathology, the prerequisite to control four virus serotypes, and inadequate investment by vaccine designers have hindered vaccine advancement.[ 45 ]

Scrupulous attempts are aimed to develop antiviral drugs that can be used to manage DF and avoid the life-threatening episodes.[ 46 , 47 ]

Dengue has evolved as a global life-threatening public health concern, affecting around 2.5 billion individuals in more than 100 countries. The physician should be aware about the varied clinical manifestations of this condition and ensure an early and adequate treatment plan. Future directions to combat this dreadful disease aim at methods of mosquito control, development of vaccine, and antiviral drug regimen.

Paragraph on Dengue Fever (200 Words)

You may read: Report on Dengue Fever for HSC

Dengue is a viral disease spread by a mosquito named “Aedes”. The “Aedes” mosquito is the culprit. The disease prevails mostly in tropical countries like ours.

The main culprit “Aedes” mosquito is born in stagnant fresh water and rainwater. There remains clogged water in flowerpots, damaged tyres, drains, waste plastic bags, and bottles around our home. Sometimes, we see water clogged on the roof of buildings. Dengue causes a sustained high-grade fever, red rashes all over the body, much pain around, inside or behind the eyes, nausea and vomiting, abdominal pain, diarrhoea, and muscle aches. There are two types of dengue.

These are classic dengue and dengue hemorrhagic. Normally, classic dengue recovery occurs more quickly but dengue hemorrhagic decreases the platelet count of the blood, It causes bleeding, organ failure or even death.

There is no vaccine against dengue. So prevention is very crucial. We must keep our household areas clean so that water can not be clogged in flowerpots, vases, tyres etc. Besides, we must protect ourselves from mosquito bites. That’s why we should always wear protective clothing like pants, long sleeves, and socks and use mosquito nets while sleeping. Above all, we had better consult a doctor if any fever persists for days.

Dengue Fever Paragraph 150 words (Class 8)

Dengue fever is a viral illness that is transmitted by mosquitoes. The symptoms of dengue fever include high fever, severe headache, joint and muscle pain, and rash. In Bangladesh, dengue fever has become a major public health concern, with frequent outbreaks occurring in recent years. The mosquito that transmits dengue fever breeds in stagnant water, which is abundant in Bangladesh due to the country’s geography and climate. Prevention measures such as eliminating mosquito breeding sites, using mosquito nets, and wearing protective clothing can help reduce the risk of contracting dengue fever. Early detection and treatment are also important for managing the illness and preventing complications. Health authorities in Bangladesh are working to increase awareness about dengue fever and improve prevention and treatment efforts to reduce the impact of this disease on the population.

The symptoms of dengue include high fever, headache, joint and muscle pain, and rashes. If not diagnosed and treated promptly, it can progress to severe dengue, which can be fatal. The Aedes mosquitoes that transmit dengue are most active during the day, so it is crucial to take preventive measures, such as using mosquito nets, wearing long-sleeved clothing, and applying insect repellent. In addition, it is vital to keep our surroundings clean and dispose of standing water, where mosquitoes breed. Dengue outbreaks in Bangladesh usually occur during the monsoon season, and the government takes measures to control the spread of the disease, such as fogging and spraying insecticides. However, the best defense against dengue is to raise awareness about the disease and take preventive measures to reduce the risk of mosquito bites.

Dengue Fever Paragraph 250 words (HSC)

Dengue fever is a mosquito-borne viral disease that has become a major public health concern in Bangladesh, with frequent outbreaks occurring in recent years. The virus is transmitted to humans through the bites of infected mosquitoes, primarily Aedes aegypti and Aedes albopictus. These mosquitoes breed in stagnant water, which is abundant in Bangladesh due to its geography and climate. The symptoms of dengue fever can range from mild to severe and can include high fever, severe headache, joint and muscle pain, and rash. In severe cases, dengue fever can lead to complications such as bleeding, shock, and organ failure.Prevention measures such as eliminating mosquito breeding sites, using mosquito nets, and wearing protective clothing can help reduce the risk of contracting dengue fever. Community participation in prevention efforts is crucial, as mosquitoes can breed in any standing water, including water in discarded containers, old tires, and flowerpots. Effective communication campaigns and education about dengue fever and its prevention are necessary to encourage communities to take action.Early detection and treatment are also important for managing the illness and preventing complications. If you suspect you have dengue fever, it is important to seek medical attention immediately. Dengue fever can be diagnosed through a blood test, and treatment typically involves rest, hydration, and pain relief medication. In severe cases, hospitalization may be required.Health authorities in Bangladesh are working to increase awareness about dengue fever and improve prevention and treatment efforts to reduce the impact of this disease on the population. The government has implemented a number of strategies, such as the distribution of mosquito nets, regular fumigation, and the establishment of dengue clinics in hospitals. These efforts have shown some success, with a decrease in the number of dengue cases reported in recent years. However, ongoing surveillance and continued prevention and treatment efforts are necessary to control this disease in Bangladesh.
