>   West Nile virus, transmitted by the northern house
>   mosquito, Culex pipiens, first appeared in the United
>   States in 1999. It was identified in Uganda's West Nile
>   District in 1937. The virus causes brain and spinal
>   cord inflammation in humans. West Nile virus infects
>   many different bird species, but it appears to be lethal
>   to crows, jays, and hawks. Mosquitoes feed on birds
>   infected with the virus and then transmit it to humans
>   and other animals.
