1. How do people get infected with West Nile virus (WNV)? People get West Nile virus from the bite of a mosquito that has fed on an infected bird. Mosquitoes can't transmit the virus from one person to another.
It's also possible to get West Nile virus from a blood transfusion or an organ transplant from an infected donor. Since all blood donated in the U.S. is tested for the virus, the blood supply in this country is considered safe.
I guess they just forgot about mentioning free range chickens.
