The recent death of a Contra Costa County resident from West Nile virus serves as a painful reminder of the ongoing threat posed by mosquitoes, particularly as tropical moisture has increased their presence in the Bay Area.

Health officials have urged residents to take precautions, emphasizing the importance of reducing exposure to mosquitoes. "This is a tragedy," said Dr. Meera Sreenivasan, the county’s deputy health officer. "This death also reinforces how important it is to reduce the risk of West Nile virus infection by reducing our exposure to mosquitoes."

The unidentified man, who lived in the eastern part of the county, is the first recorded death from the virus in Contra Costa County since 2006. Additionally, a dead bird and five sentinel chickens in Oakley have tested positive for the virus this year, signaling its presence in the area.

West Nile virus is the leading mosquito-borne disease in the continental United States, with around 2,200 infections reported annually. About one in 150 people infected develop serious illness, making prevention critical.

To protect yourself, use insect repellents approved by the U.S. Environmental Protection Agency (EPA), such as those containing DEET, Picaridin, or Oil of Lemon Eucalyptus. Additionally, avoid allowing standing water to accumulate in your yard, which can become breeding grounds for mosquitoes.

Residents are encouraged to report dead birds, often the first sign of West Nile virus in an area, to the California Dead Bird Call Center at westnile.ca.gov or 877-968-2473. By staying informed and taking preventive measures, we can reduce the risk of this dangerous disease.
