The West Nile virus mainly affects birds, but humans may get infected with the disease if they are bitten by mosquitoes that previously fed on an diseased bird.
Symptoms in humans include headaches, fever, nausea, fatigue, skin rash or swollen glands, according to health officials. Infection could also lead to death in rare cases.
The best way to avoid becoming infected with West Nile virus is to protect oneself against mosquitoes, according to the county.
This includes dumping out water collected around homes to prevent mosquitoes from breeding and wearing long sleeves and pants or using insect repellent while spending time outdoors.
Insect repellent should contain DEET, picaridin, lemon eucalyptus oil, para-menthane-diol, 2-undecanone or IR3535, health officials say.
Plus, people should also secure their screens on windows and doors to keep insects away, according to the county. Other tips can be found on the county website.
Increased mosquito sightings, unmaintained swimming pools and dead birds may be reported to the County Vector Control Program at (858) 694-2888 or vector@sdcounty.ca.gov.
The county says no human cases of West Nile have been reported so far this year.

West Nile Virus Detected In Three Dallas County Locations
Dallas County Health and Human Services confirmed West Nile virus in mosquito pools across three locations this week, marking the first positive tests in the county for 2025. Mosquito samples collected in Irving's 75061 ZIP code, Richardson's 75080 ZIP code, and Rowlett's 75088 ZIP code tested positive for the virus, which is primarily spread by infected mosquitoes. However, other bloodsucking arthropods, such as fleas and ticks, can also transmit the virus. The findings follow Tarrant County Public Health's report of a positive mosquito sample on May 8, signaling the start of the West Nile virus season in North Texas, which typically spans May through October. Summer heat fuels mosquito activity, increasing the risk of virus transmission. Most cases occur during mosquito season, which starts in the summer and continues through the fall. While most infected individuals show no symptoms, about 1 in 5 may develop fever, headache, body aches, or joint pain. In rare cases, about 1 in 150 infected persons may develop a serious, or even fatal, illness affecting the brain or nervous system. The virus can rarely be transmitted through blood transfusions, organ transplants, breastfeeding, or from mother to baby during pregnancy, but not through person-to-person contact like touch or saliva. To curb the spread, Dallas Health and Human Services recommends using DEET or EPA-approved repellents daily, wearing long, loose, light-colored clothing outdoors, draining standing water around homes, and limiting outdoor activity at dusk and dawn when mosquitoes are most active. The cities of Irving, Richardson, and Rowlett have begun spraying high-risk areas to prevent further spread. No human cases have been reported in Dallas County this year, and officials urge residents to remain vigilant as the season progresses.

Coronado beach closure lifted by county health officials
Above: KUSI report on Sen. Corey Booker touring the Tijuana River on Thursday, May 29. CORONADO, Calif. (FOX 5/KUSI) — County health officials have lifted the closure of Coronado's shoreline that was put in place over Memorial Day weekend. The ending of the closure was accompanied by the issuance of advisories for La Playa Beach near Lawrence Street in Point Loma and the water near the Coronado Lifeguard Headquarters due to bacteria levels that exceed state health standards. The entire western shoreline of Coronado — from Avenida Lunar in the south to North Beach in the north — was first closed on Saturday due to the flow of sewage from the Tijuana River Valley. The closure came on the heels of a period with worse-than-normal conditions for South County residents amid work to the sewage treatment system on the other side of the border. Sen. Cory Booker tours Tijuana River sewage crisis The repairs earlier this month to a critical line connecting the San Antonio de los Buenos Plant in Mexico to the South Bay International Wastewater Treatment Plant in the U.S. required the diversion of wastewater into the Tijuana River. When the repairs began, Mexican and U.S. officials noted the South Bay treatment plant would try to collect as much of the extra wastewater as possible, but it could lead to temporarily increased sewage flows. The work was completed last week and concluded with minimal sewage flows crossing the border, according to a post on X by the U.S. International Boundary and Water Commission, which oversees the South Bay treatment plant. With the lifting of the Coronado shoreline closure, the county's ongoing beach management actions have returned to what has become normal in recent years: closures limited to perennial problem spots close to the Tijuana River estuary, like Silver Strand and Imperial Beach. As of Wednesday, advisories due to levels of bacteria exceeding state standards are also in place for other area that regularly see health warnings like La Jolla Children's Pool, North Cove Vacation Isle in Mission Bay and the La Jolla Cove.
