West Nile Virus Cases Rise In San Diego County; Mosquito Spraying Planned  Patch

County crews will spray about 6,000 properties after mosquitoes tested positive for West Nile virus. SAN DIEGO, CA — San Diego County will spray thousands of properties for mosquitoes this week as the region reports its highest number of locally acquired West Nile virus infections in a decade. As of Sept. 16, 11 human cases of West Nile virus had been reported in the county this year, including three involving Coronado residents, according to county officials. It is the highest number of local infections since 2016. County Vector Control crews are scheduled to conduct truck-mounted pesticide treatments across about 6,000 properties in Coronado from 1 to 6 a.m. Friday and Saturday. The treatment area generally stretches from Second Street south to Ocean Boulevard and from F Avenue east to Glorietta Boulevard.

The treatments come after county mosquito surveillance found elevated numbers of mosquitoes in Coronado, including some that tested positive for West Nile virus. Additional treatments could be conducted next week depending on conditions. Crews will use AquaDuet, a pesticide approved by the U.S. Environmental Protection Agency. County officials said the mist is nearly invisible, dissipates in less than 30 minutes and does not pose a risk to people or pets as applied. The treatments are scheduled during early morning hours when fewer people are outdoors. Beekeepers and residents who
