West Nile virus
Prevention

Despite the commercial availability of four veterinary vaccines for horses, no human vaccine has progressed beyond phase II clinical trials. Efforts have been made to produce a vaccine for human use and several candidates have been produced but none are licensed to use. The best method to reduce the risk of infections is avoiding mosquito bites. This may be done by eliminating standing pools of water, such as in old tires, buckets, gutters, and swimming pools. Mosquito repellent, window screens, mosquito nets, and avoiding areas where mosquitoes occur may also be useful.
