Topline:

Officials in Orange County are reporting the first detection of West Nile virus in mosquitos this year.

Where? Mosquitos collected in the Newport Beach area have tested positive for West Nile, according to Orange County Mosquito and Vector Control District. The infected insects were collected in an area bordered by Campus Drive, Jamboree Road, State Route 73 and John Wayne Airport. according to the OCMVCD.

Any humans infected? There are no reported cases so far of West Nile in humans in Orange County.

What’s West Nile again? For humans, the CDC says the virus is commonly spread through the bite of the infected insects and can lead to severe illness affecting the central nervous system. Symptoms can include: fever, headache, body aches, vomiting, diarrhea or rash.

What’s being done about it? Vector Control workers will continue inspections to try and tamp down on mosquito breeding.

What you can do: O.C. officials said dumping and draining standing water at least once a week is the best way to limit the pests in your community.
