Malaria

Malaria is spread to people through the bite of infected mosquitoes. This disease, caused by a parasite, is not spread in the United States; however, residents can acquire the disease by traveling to countries where malaria is present. It is found in sub-Saharan Africa, South Asia, and parts of Central and South America.

In Connecticut, surveillance is conducted to identify travel-related cases. Treatment varies depending on symptoms and the species of the malaria parasite causing the illness. While there are medications to help prevent infection with malaria, the best way to protect yourself and your family is to preventmosquito bites.
