Public health officials confirmed on Thursday that a resident of Solano County tested positive for West Nile virus.

The patient is a resident of Vacaville, where the first known local transmission of West Nile virus was announced last month.

"West Nile virus is most commonly transmitted to people and animals through the bite of a mosquito infected with the virus," Dr. Christine Wu, the deputy health officer for Solano County, said in a statement.

"Residents should take the necessary precautions to reduce the risk of getting an infection by using insect repellent when spending time outdoors and removing standing water sources around the home," Dr. Wu said.

The California Department of Public Health says seven people have tested positive for West Nile virus in the state since the start of the year.

Health experts say the majority of people who are infected with West Nile virus will not develop symptoms. About one in five people infected with the virus may develop mild flu-like symptoms; in rare cases, infections can be fatal if not treated.

Individuals who think they may have been infected with the virus should contact their primary care doctor. If an infection is confirmed, the hospital or health care center where the patient is treated will contact county health officials.

West Nile virus is transmitted through mosquito bites. Dead birds can be a sign of a region with an infestation of mosquitos that are transmitting the virus. Dead birds can be reported by visiting or by calling 1-877-968-2473.

Residents can discourage mosquitos from nesting and breeding in their areas by draining standing water, including water that may be in pools, flower pots and ponds.
