West Nile Virus infects mainly birds and occasionally other species of animals, including humans.

 How West Nile Virus is transmitted
Mosquitoes become virus carriers after biting infected birds. These mosquitoes can transmit the virus by biting an animal or a human afterwards. The virus spreads through the blood and can cause an infection. Current knowledge leads us to believe that in a region where the virus is transmitted between birds and mosquitoes, fewer than 4 people per 100 will be infected.

 What are the symptoms of an infection?
Most people who are infected show no symptoms or only a light infection, sometimes accompanied by headaches, fever, pimples or red spots on the skin, and body aches. People with unusually severe headaches should seek immediate medical attention.

 How can you help with the detection of the virus
The presence of dead or sick birds is one of the first signs indicating that the West Nile Virus is present in a region. Do not touch these animals with your bare hands since they can be carrying this or other diseases. You should immediately report any dead or sick crows, ravens, or blue jays you find in the region by calling 1-800-363-1363. These birds are the mose susceptible to this infection and consequently, are the only ones to be analyzed.
