About West Nile Virus According to the Centers for Disease Control and Prevention (CDC), West Nile virus (WNV) is spread by the bite of an infected mosquito. Eight out of ten individuals infected with the WNV, will not exhibit symptoms. But, about one in five will develop symptoms that include fever, headache, body aches, nausea, or skin rash. The symptoms can last for several days to months. One in 150 people infected with the virus develop severe symptoms including convulsions, muscle weakness, neck stiffness, coma, paralysis and possibly death. People over 60 years of age and those with chronic health problems are at higher risk of severe illness. There is no vaccine for West Nile virus and no specific treatment for West Nile virus infection. While not all mosquitoes carry this virus, the type of mosquito that spreads this virus is found throughout Ross County.
