San Diego County health officials are urging residents to protect themselves from mosquito bites after several human cases of West Nile virus were reported this summer, according to the County of San Diego Communications Office in a report published by East County Magazine.

West Nile virus mainly affects birds, but mosquitoes can spread it to people after biting infected birds. County officials said most people who get the virus have no symptoms or only mild illness, while rare cases can cause severe illness or death.

The county’s Vector Control Program works year-round to reduce mosquito-borne illness, but officials are asking residents to help by dumping or draining standing water from plant saucers, clogged gutters, buckets, toys, old tires and wheelbarrows. Residents are also encouraged to use repellent and keep door and window screens in good repair.

The reminder is practical for Santee households heading into the holiday weekend because warm weather, irrigation and even small containers of standing water can create mosquito breeding spots around yards and patios.

Residents can report increased mosquito activity, green pools or dead birds to County Vector Control through SDVector.com or by calling (858) 694-2888, according to the county.
