Twenty-six more mosquito samples tested positive for West Nile virus this week in Los Angeles County, bringing to 264 the number of positive samples so far this year, vector control officials reported Friday.
The mosquito samples all were collected from areas previously identified as positive for WNV, according to the Greater Los Angeles County Vector Control District. The highest totals of mosquitoes that have tested positive this year were reported in: Encino and North Hollywood with 14 each, Valley Village with 13, Van Nuys and Pico Rivera with 12 each and Studio City and Toluca Lake with 10 each.
West Nile virus is endemic in Los Angeles County, and warm temperatures can increase virus activity and mosquito populations, according to the GLACVC. As of Oct. 2, 93 WNV human cases have been reported in California this year, 27 of which were identified by the Los Angeles County Department of Public Health.
