What are the risks and symptoms of West Nile virus?
Very few mosquitoes are infected with the virus, according to the CDC. Even if the mosquito is infected, less than 1 percent of people who are bitten and become infected will become severely ill. About 20 percent of people who contract West Nile virus will develop West Nile fever. Symptoms include fever, headache, tiredness and body aches, occasionally with a skin rash and swollen lymph glands.
