The number of West Nile virus cases in the United States can vary significantly from year to year. On average, the Centers for Disease Control and Prevention (CDC) report several hundred cases annually, with occasional spikes during peak mosquito season. Since the virus was first identified in the U.S. in 1999, thousands of cases have been documented, but most infections are mild or asymptomatic. For specific statistics, it's best to consult the latest CDC reports or public health data.
The virus is carried by mosquitos-- not too many of them around in the winter.
West Nile virus is spread by the bite of an infected mosquito, and can infect people, horses, many types of birds, and some other animals. Most people who become infected with West Nile virus will have either no symptoms or only mild ones. However, on rare occasions, West Nile virus infection can result in severe and sometimes fatal illnesses. There is no evidence to suggest that West Nile virus can be spread from person to person or from animal to person.
