West Nile Virus is spread by the bite of a mosquito that has bitten an infected bird. The virus can infect people, horses, many types of birds, and some other animals. Most people who become infected with West Nile Virus don't experience any symptoms
- Approximately 20% of infected people will experience mild to severe flu-like symptoms
- Approximately one in 150 people infected with West Nile Virus experiences severe encephalitis, which can sometimes be fatal.
From 2003 to 2012, we tested Corvid birds (crow, ravens, jays) and mosquiotoes and none were positive for the West Nile Virus. We have yet to see a locally acquired case of human West Nile Virus infection. However. the Fraser Health region does have the type of mosquitoes that can spread the virus, and the virus is expected to arrive.
