Anopheles quadrimaculatus mosquito


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 foreign endemic areas. 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 is available and is dependent on symptoms and the species of the malaria parasite causing the illness. Although there is medication to help prevent infection with malaria, the best way to prevent getting sick is to prevent mosquito bites.
