What is Dengue Fever?

Researchers at the Indian Institute of Science in Bengaluru recently revealed that the Dengue virus in India has evolved dramatically.

About Dengue Fever:

It is an illness spread by the bite of mosquitos infected with one of the dengue viruses.
It is spread by Aedes mosquitos, which also carry viruses like Zika and chikungunya. 
The virus is most commonly found in tropical and subtropical regions, including Central and South America, Africa, parts of Asia and the Pacific Islands.
Mild dengue fever causes a high fever and flu-like symptoms.
The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
It isn’t contagious from person to person except when passed from a pregnant person to their child.
Treatment: There is no specific treatment for dengue. The focus is on treating pain symptoms.
