(COUNTY NEWS CENTER) – A 91-year-old man from La Jolla has been confirmed as the first person in San Diego County in 2018 to test positive for West Nile virus, the County Health and Human Services Agency announced Friday.
The man was hospitalized in September with encephalitis but was confirmed later to have West Nile virus after testing done by the California Department of Public Health. He has been discharged from the hospital and is still recovering.
The man had not traveled outside the county within the month prior to becoming ill, so the infection resulted from a local mosquito bite. The County’s Department of Environmental Health trapped mosquitoes near his residence and is sending precautionary notices to residents in the area with information on mosquito prevention and protection. Mosquitoes recovered from those monitoring traps tested negative for West Nile virus.
