6. La Crosse Encephalitis 

There are about 65 cases of this virus each year in the U.S. The mosquitoes that carry it bite during the day, usually in the spring through early fall. They live in wooded areas in the upper Midwest, mid-Atlantic, and Southeast. If you get sick, you might get a fever, nausea, and headache, and severe cases can cause nervous system changes.
