Dengue is a mosquito transmitted disease that poses a global danger to public health. In different tropical and subtropical regions, the dengue virus is a major arbovirus. Along with the increase in the number of cases and its severity, there has been a shift in the geographical range of this disease.

From only being restricted to urban areas it has now started affecting rural citizens as well. Unorganized urbanization, drastic environmental changes, host–pathogen interactions are few factors that are known to have increased its spread in the country. Inadequate vector control measures can also be blamed for this.


Dengue can be fatal if not diagnosed and cared for at the correct time.

Here are some interesting facts on dengue fever:

  1. Symptoms of dengue fever are those of any other flu

Dengue initially causes symptoms just like those of common flu.

After 5 to 10 days from the bite of the aedes mosquito, true symptoms occur.

  1. No medicine to treat this fever

Keeping the body hydrated and getting enough rest are the only known ways to treat yourselves from dengue quickly.

The Aedes aegypti mosquito breeds in the daytime. A bite by this mosquito causes the dengue fever. Its favourite spot being below the elbow and knee.

  1. This mosquito breeds in a specific environment

Just the Aedes mosquito bite and not the touch with an infected individual will make it transmit.

  1. Dengue can get fatal

Dengue can even lead to death if symptoms are not taken care of in time.

People who are overweight tend to attract more mosquitos as they exhale a lot of carbon-di-oxide.

  1. Platelet count in humans is between 150,000- 350,000

Having a good platelet count helps you to recover quicker from injuries and also helps to prevent problems like anaemia.
