How is the west nile virus transmitted?

West Nile Virus: Typically, west nile virus spreads to humans via infected mosquitoes. Mosquitoes become infected when they feed on infected birds. You can not get infected by touching or kissing a person with the virus. In some cases, the virus may be spread by organ transplantation and blood transfusions.

Mosquito and Robins: West nile virus must be produced in high numbers before being passed through mosquitoes. Birds are far and away the most frequent carriers. Robins look like they might be responsible for spread all over the country. Mosquitoes have to feed on the infected robin and then pass the virus on to human beings through a bite.
