West Nile Virus: An Update

Course overview

Since its introduction nearly 20 years ago, West Nile Virus (WNV) it has been responsible for two nationwide epidemics and has infected thousands of people. WNV is primarily transmitted via the bite of an infected mosquito. Humans and horses can become infected with WNV and experience mild to severe disease. Although there are currently licensed vaccines for horses, there is no WNV vaccine for human use. Additionally, there is no treatment for WNV other than supportive care. Identifying cases of WNV infection can also be difficult because it shares clinical symptoms similar to those of other flaviviruses. Monitoring is required for years after recovery because neurological sequelae can persist. Through the use of education and surveillance programs, the IP healthcare team can proactively limit the spread of WNV and prevent future epidemics.
