With Swine flu and dengue fever wreaking havoc across the nation, it’s time to remember and abide to the most popular adage-’Prevention is better than cure’.

Here’s an article from our experts that gets you covered about the most effective prevention tips, cure, home remedies and lesser known facts about Dengue fever. Let’s get started.

Dengue: Important facts

Dengue (also known as Breakbone fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today, this disease is widespread among Asian and Latin American countries and has become a leading cause of hospitalization among children and adults in these regions. The causes of Dengue include population growth and urbanization, lack of sanitation and ineffective mosquito control.

The Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and Ae. albopictus. This mosquito is also known to transmit water borne disease like chikungunya, yellow fever and Zika infection.

There are 4 different, but closely related serotypes of the virus that cause dengue (DEN-1, DEN-2, DEN-3 and DEN-4). When a person recovers from infection from one particular serotype, it provides lifelong immunity against that serotype. This finding implies that when a person gets infected by dengue for the second time, he/she may have developed immunity for the first serotype but not for the second one. However, cross-immunity to the other serotypes after recovery is only partial and temporary.


Dengue is spread through a cycle of human-to mosquito- to human and not human-human cycle.

The infected Aedes aegypti mosquito is the primary vector of dengue. A vector is a vehicle that carries and transmits a disease to its host organism. The virus is then transmitted to humans through the bite of the infected mosquito which could transmit the virus to multiple hosts after an incubation period of 4–10 days.

It could also be transmitted when an uninfected Aedes aegypti bites an infected human. When this happens, the blood of the mosquito gets infected with dengue virus and this is how the cycle repeats.

A lot of people are under the misconception that dengue is caused by night biting mosquitos. This is however, not true. Dengue typically affects kids and older age people due to day biting mosquitoes. And thus, you must be as cautious in daytime as you are at night. It’s always best to wear full sleeved apparel while doing to places with high number of mosquitos.

Citrus limetta, the fruit from the citrus family, also has the ability to increase the platelets count. However, this too, has no scientific evidence from doctors.

Ensure that you take a lot of fluids like coconut water, papaya leaf juice, neem juice and other juices at frequent intervals to keep your body well hydrated. Staying hydrated also reduces the symptoms of headaches,muscle cramps and helps in flushing out excess toxins from your body.
