SAN DIEGO–The number of people in San Diego County who have tested positive for West Nile virus — confirmed and probable cases — this year has increased to 30 including five deaths, County officials said Wednesday.
That number is an increase from 22 people a week ago and includes a newly confirmed death, County Health and Human Services Agency officials said. The 30 cases include 27 confirmed human cases including four deaths, three that were previously reported, and three probable cases, including one previously reported death.
The California Department of Public Health uses patient symptoms and blood and spinal fluid tests to classify possible West Nile virus cases as “confirmed,” “probable,” “suspected” or “not a case.” For public reporting, state public health and the County consider both “confirmed” and “probable” cases as West Nile virus infections.
The latest confirmed death was a 62-year-old San Diego man, who died Oct. 15.
At the start of September, San Diego County had just one confirmed human case. This week County public health and environmental health vector control officials reminded people to follow the County’s “Prevent, Protect, Report” guidelines to protect themselves from mosquitoes that can transmit West Nile virus to humans from infected birds and animals.
