So far, 38 states have reported human cases, but the epicenter is Texas, which has reported half of the WNV infections. The CDC said so far it has received reports of 1,118 cases, including 629 people with the neuroinvasive form of the disease. Nationally, 41 deaths have been reported.West Nile virus has no vaccine and no cure and can cause permanent neurological sequelae or death in about 1 in 150 people infected. About 80% of those infected do not experience any symptoms but 20% will have moderate symptoms that mimic the flu and can last from days to weeks even in healthy people.
Forty-seven states have detected West Nile Virus in either humans, birds or mosquitoes. You can navigate the maps to view the status of your area. It is imperative that people follow the guidelines for preventing WNV. In areas where standing water cannot be removed such as rainbarrels and ornamental ponds, use mosquito dunks to control larvae (this is not an endorsement of a specific product but rather an example).
