About dengue fever

Dengue fever is a tropical infection caused by a virus. It is a mosquito-borne illness that spreads when an infected mosquito bites a person. This usually causes flu-like symptoms which can range from mild to severe. Dengue can be caused by one of the four viruses spread by the Aedes aegypti mosquito. It is not a contagious disease, meaning, it cannot spread from one person to another.

Dengue fever causes

Dengue fever causes

Primarily, dengue fever causes include being bitten by an infected mosquito. It can only transmit from one person to another when a mosquito first bites an infected person and then bites a healthy person. Hereby, the virus enters a person’s bloodstream leading to an infection. 

Once you have recovered from this fever, your body develops life-long immunity against this virus. However, you will only gain immunity against the one type of virus you have been infected with and not the other three. This means that you can still be infected by the rest of the viruses. 

Dengue fever causes can occur in anyone. However, some people are more prone to be infected by this virus than others. Common risk factors include:

Dengue fever, if not treated timely and properly, can cause severe complications. It can lead to organ damage and internal bleeding.
