County workers found West Nile virus in two dead crows picked up near Rolando and Skyline. This is a good reminder that people should take steps to protect themselves from mosquito bites, because mosquitoes can spread the virus.
Mosquito season usually starts in April. The County is reminding everyone to follow three steps: Prevent, Protect, and Report: Prevent mosquito breeding at home, protect yourself from bites, and report mosquitoes and dead birds to the Vector Control Program. One of the best ways to stop mosquitoes is to remove standing water around your home so they can’t breed in it.
These birds are some of the earliest signs of West Nile virus activity in the County this year. There are no local human cases so far. West Nile virus mainly affects birds, but mosquitoes can pass it to people if they bite an infected bird and then bite a person.
Most people who get West Nile virus have no symptoms or mild symptoms like headaches, fever, nausea, feeling tired, skin rash, or swollen glands. In rare cases, it can make people very sick or even cause death.
Protecting yourself from mosquitoes is always important. Mosquitoes can live near people — in backyards and even inside homes. Some types of mosquitoes can also spread other diseases like chikungunya, dengue, and Zika, but only if they bite someone who already has those illnesses.
The County recommends these steps:
Prevent mosquito breeding
- Dump out anything that holds water, like plant saucers, gutters, buckets, toys, old tires, and wheelbarrows.
- Get free mosquito‑eating fish from the County to put in things like ponds, fountains, or unused swimming pools.
Protect yourself from bites
- Wear long sleeves and pants outside, or use insect repellent.
- Use repellents with DEET, picaridin, oil of lemon eucalyptus, or IR3535.
- Make sure your window and door screens are in good shape.
Report mosquito problems and dead birds
- Report more‑than‑usual numbers of mosquitoes, swimming pools that have turned green, standing water, or dead birds (crows, ravens, jays, hawks, owls).
- Call (858) 694‑2888 or email vector@sdcounty.ca.gov.
