West Nile virus was found in two dead birds and mosquitoes in eastern Contra Costa, the county Mosquito & Vector Control District said Friday.
The district warns the virus peaks in August and September, when baby birds leave nests and mosquitoes bite more often.
So far in 2018, there was one other dead bird and four other groups of mosquitos who tested positive for the virus in Contra Costa County, the district said.
“This puts people at higher risk of virus transmission and so it’s important for Contra County residents to take steps now to avoid mosquito bites,” said Steve Schutz, the district’s scientific programs manager.
