First case of West Nile virus for 2019 reported in Sutter County

West Nile virus has been detected in Sutter County for the first time so far in 2019, in one human patient as well as in mosquito samples, the Sutter-Yuba Mosquito and Vector Control District said Friday.

The Sutter County Health Department reported an asymptomatic human had tested positive for West Nile virus, the vector control district said in a news release. Recent mosquito samples west of Yuba City also tested positive, the release said.

The district warns mosquito populations may increase with high temperatures, which are incoming this weekend.

Any resident who sees a dead bird should report it to the state Department of Public Health, at

The district in late June announced “ultra low volume” pesticide spraying in the Yuba-Sutter region.

So far this year, mosquitoes and a dead bird have tested positive for West Nile virus in Sacramento County.

Last year in California, the disease infected 200 people, killing 11.
