Dengue Fever

Dengue fever is an infection caused by mosquitoes that is common in sub-tropical as well as tropical regions of the world.  In the recent years, the spreading of dengue fever has increased mainly in the semi-urban as well as urban areas and turned to be one of the major concerns of public health internationally. Dengue Haemorrhagic Fever was recognized initially in the early 1950's at the time of dengue outbreak in Thailand and nearby Philippines. But at present, it has attacked most of the Latin American as well Asian countries and turned to be the leading cause for the death of children in the region. There are four specific but very closely associated virus serotypes that cause this fatal disease; DEN-1, DEN-2, DEN-3 & DEN-4. Recovery from any particular serotype will provide lifelong immunity for only that serotype. Repeated infections from other serotypes can result in the development of severe dengue.

 

Some of the Key Facts About Dengue Fever

 

Let's take a look at some of the key facts of Dengue fever

 

1. Dengue is the viral infection caused by mosquito

 

2. Infection starts with flu and slowly develops into a fatal condition called the severe dengue

 

3. The global occurance of Dengue has increased dramatically in the recent years

 

4. More than half of the population globally is under the risk of dengue

 

5. Dengue is mainly found in the sub-tropical and tropical climatic conditions globally and mostly in the semi-urban and urban areas.

 

6. It is one of the major reasons for the increase in the death rate of children

 

7. Dengue fever has no specific treatment technique, but early identification and proper medical care can reduce the rates of fatality

 

Transmission of Dengue Fever

 

Dengue fever is caused by mosquito Aedes aegypti which is the initial vector of the disease. The infection normally gets spread to humans when they get a bite from the female infected mosquitoes. After the incubation period of the virus (4-10 days) the infected mosquito starts spreading the virus for its entire life. It is the infected humans who are the chief carriers or multipliers of dengue virus as they serve as the source for virus for the mosquitoes that are uninfected. Patients who are infected with dengue virus can easily spread the infection through the Aedes mosquitoes after they develop the initial symptoms. The mosquitoes that cause dengue fever is found mostly in the urban habitats and they breed mostly in the containers. Unlike other categories Aedes is actually a daytime feeder and the peak biting time is early mornings and evenings that too before dusk. And at the time of each feeding period the female Aedes mosquito infects multiple victims.

 

Symptoms of Dengue Fever

 

It is a severe condition that starts with flu and affects the infants, young kids and even the adults, but rarely causes death. You can suspect dengue if you have high fever accompanied by pain at the back of the eyes, severe headache, nausea, pain in muscles and joints, swollen glands or rashes and vomiting. The symptoms last for about two to seven days from the incubation period of virus after you receive a bite from the infected mosquito. The condition of severe dengue is fatal as it involves the leaking of plasma, respiratory distresses, accumulation of fluid, immense bleeding and even impairment of organs. Warning signs starts after three to seven days from the signs of initial symptoms with a drastic decrease  in the body temperature after the first two days followed by an increase in the same consistent vomiting, fast breathing, severe abdominal pain, bleeding in the gums, restlessness, vomiting blood and also fatigue. The next one day can be highly fatal and without proper medication or care can even cause death of the patient.

 

Treatment for Dengue

 

The most shocking fact is that Dengue fever doesn't have any specific treatment. In case of severe infection proper medical care from the experienced doctors and nurses can save the life of the victim. With proper medical treatment the rates of mortality can be reduced to even less than a percent. The most critical part is to maintain the body fluid of the patient who is infected with dengue.

 

Prevention and Control

 

Currently the only method to control or prevent the infection or transmission of dengue fever is to control the Aedes mosquitoes. By taking measures you can avoid getting the infection from the infected mosquitoes.

 

 

Below are Some of the Important Prevention Methods that Can Guide You to a Healthy Living:

 

1. Preventing the growth mosquitoes from various inhabit that can give access for laying egg by managing your surroundings and environment.

5. Windows screen should be a must in all the houses and flats. Also try to wear long sleeved dresses, materials that are treated with appropriate insecticides to avoid getting infected.

 

6. Use mosquito repellents or coils during early morning and evening when there is heavy chance of getting mosquito bites.

 

7. Applying insecticides especially during outbreaks as an important prevention measure for dengue fever.

 

Immunization for Dengue Fever

 

Till now no vaccination has been discovered for dengue fever. Developing vaccines again this fatal disease has been a great challenge for the researchers. There has been a progressive development in the field of this research off late and many people are involved in this hardened process of finding the right prevention for Dengue fever. WHO has been providing technical assistance and guidance to several countries and their partners to support their move towards evacuating this disease. There are several candidate vaccines that are in the different phases of these trials.

 

The incidence of this fatal disease has grown unexpectedly around the globe in these recent years. The adaption capacity of the Aedes mosquito to survive even in low temperatures has increased the rate of infections around the world. Try to keep your premises clean and walk towards a future that is devoid of this fatal phenomenon.
