Yes, it could. Malaria is caused by a parasite, not a virus. Not all species of mosquitoes are capable of transmitting the malaria parasite, but ones that can exist in much of the United States. Most cases of malaria in the US are imported from other countries, but cases transmitted here have been reported. If you have malaria, you should be protected from mosquito bites to avoid spread to others. In the warmer seasons, this may mean staying in air conditioned or screened areas, using insect repellent, and sleeping in a bednet.

First of all, Malaria is definitely not a virus. Malaria is a parasite.

Second, it does not stay in your blood for a lifetime. If you have malaria, you should be treated. after an effective treatment you will be free of any malaria parasites. (one strain could stay in your liver for up to 4 years, but not much longer than that)

On the mosquito question, that depends on the kind of mosquito. As far as i know, only mosquitoes in the 'Anopheles' family can effectively transfer malaria to humans. So if any mosquitoes from that particular family are living in your area, then it would be a possibility.

Nicholas - Welcome to Answers. If you had malaria, you would almost certainly know by now. Malaria is not a virus, but rather a tiny protozoan parasite of the family (Genus) Plasmodium. The 4 types of human malaria are caused by P. falciparum, P. ovale, P. malariae, and P. vivax. All 4 are routinely cured by medicine. Undetected low level infection with P. malaria alone has been known to last several years in humans without being detected but can be cured once diagnosed. Malaria is transmitted exclusively through the bites of Anopheles mosquitoes, almost but not completely eliminated in the USA where they are sometimes found in lower California near the Mexican border. Occasionally a traveler, like yourself, could bring the infection back unless they carefully took their anti-malarial medicine when they travel in Africa or India, like I do. Even if you had an undetected infection, about the only way to pass it on to another person would be directly through blood transfusion or sharing of "dirty" needles by drug abusers. You're okay. Rest easily and peacefully.

THe simple answer seemingly is probably no, because the malarial parasite relies on particular species of mosquito not usually found in the US, probably some parts such Florida might have it though:

With proper treatment malarial parasites cab be cleared from the bloodstream according to the site above.

Malaria is not at all caused by any virus
