Mosquito Pool Tests Positive for West Nile Virus

Mosquito Pool Tests Positive for West Nile Virus

Champaign County tends to get positive samples for West Nile virus every year, and like last year, its first positive sample turned up earlier in the summer than usual, Blackford said.

The California Department of Public Health/West Nile virus program notified the County of Santa Cruz on Thursday of the summer's first find of a West Nile virus positive dead bird in Santa Cruz County.

The first human case of the virus this season occurred recently in the Chicago area.

The department also confirmed the first mosquitoes to test positive for West Nile virus in IL for 2018.

Mosquitoes spread the infection by biting birds. Often there are no symptoms, but those older than 60 are more likely to die or to develop a severe illness.

However, four out of five people infected with West Nile virus will not show any symptoms, according to the Illinois Department of Public Health. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur.
