Bird Tests Positive for West Nile Virus

Reading Time: 2minutes

A dead American Crow found in the Clairemont area of San Diego has tested positive for West Nile virus, prompting County environmental health officials to remind people to protect themselves from mosquitoes that can transmit the virus to people.

County officials said people should continue to follow the County's "Prevent, Protect, Report" guidelines, including finding and dumping out standing water around homes to keep mosquitoes from breeding.

The crow is the first dead bird to test positive for the virus in San Diego County this summer, but there have been no locally contracted human West Nile virus cases reported this year.

However, West Nile virus remains a potentially deadly threat. In 2015, 44 San Diego County residents tested positive for West Nile virus and six county residents died.

West Nile virus is mainly a bird disease, but it can be transmitted to humans by several types of mosquitoes if they feed on an infected bird and then bite people.

Some people who become infected can suffer symptoms, including headache, fever, nausea, fatigue, skin rash, or swollen glands. But in rare cases, West Nile virus can make people extremely ill and even kill them.

Protecting against mosquitoes is always important in San Diego County.

County officials advise that people should help protect themselves from mosquitoes and potential illnesses by following the County's "Prevent, Protect, Report" guidelines.

Prevent mosquito breeding

Dump out or remove any item inside or outside of homes that can hold water, such as plant saucers, rain barrels, buckets, garbage cans, toys, old tires, and wheelbarrows. Mosquito fish, available for free by contacting the Vector Control Program, may be used to control mosquito breeding in backyard water sources such as stagnant swimming pools, ponds, fountains, and horse troughs.

Protect yourself from mosquito bites

Protect yourself from mosquito-borne illnesses by wearing long sleeves and pants or use insect repellent when outdoors. Use insect repellent that contains DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol, 2-undecanone or IR3535. Make sure screens on windows and doors are in good condition and secured to keep insects out.

Report possible mosquito activity and dead birds

Report increased mosquito activity, or stagnant, green swimming pools and other mosquito-breeding sources, as well as dead birds - dead crows, ravens, jays, hawks and owls - to the County Vector Control Program by calling (858) 694-2888 or emailing [email protected].
