Mosquito-Borne Diseases

Mosquitoes cause more human suffering than any other organism with over one million people dying from mosquito-borne diseases every year. Mosquito-borne diseases include protozoan diseases, such as malaria, filarial diseases, such as dog heartworm, and viruses, such as dengue, encephalitis and yellow fever. Yellow fever, dengue and malaria which were once prevalent in the United States are now rare.

Mosquito-borne encephalitic strains have a global distribution, but there are three encephalitic strains of concern in Leon County: Eastern Equine Encephalitis (EEE), St. Louis Encephalitis (SLE) and West Nile Virus Encephalitis (WNV), all of which are transmitted by mosquitoes. Most cases of these encephalitis in Leon County occur from June through October, when mosquitoes are most active.
