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 June to October 2009, over 125 corvids (crows, ravens, jays) and more than 90,000 mosquitoes were submitted for testing from Fraser Health. None tested positive for the West Nile Virus.
