Filarisasis (heartworm)

Filariasis is caused by a nematode (roundworm) and transmitted by Culex and Anopheles mosquitoes. The Filariasis is still an epidemic in Africa and Asia. There are no recorded human cases in the USA and Florida , but dog heartworm (Dirofilaria immitis) is very common and can be a life-threatening disease for canines. Dogs and sometimes other animals such as cats, foxes and raccoons are infected with the worm through the mosquito bite. The major disease vector is the salt-marsh black mosquito, Ochlerotatus taeniorhynchus.  Please contact your local veterinarian to inquire about heartworm preventatives for your animal.
