Deadly Mosquito-Borne Diseases Remain Without Cure

Mosquitoes, the world's deadliest insects, spread serious diseases.

Some of these diseases, like Chikungunya, Japanese encephalitis, Zika, West Nile, and dengue fever, have no cure.

Chikungunya causes fever and joint pain.

Japanese encephalitis inflames the brain and is often found in Asia.

Zika is especially dangerous for pregnant women.

West Nile can cause flu-like symptoms and sometimes affect the nervous system.

Dengue fever leads to high fever and pain, and can be deadly.

The rainy season is when mosquitoes breed, increasing the risk of these illnesses.
