San Francisco Public Health Officials reported a second influenza-related death late Tuesday evening. Officials said that the non-elderly adult had an underlying medical condition.
The strain of the influenza remains unknown and will take several days to identify.
The first death of a San Francisco resident this season occurred in December 2013. Officials said that the initial victim also had an underlying medical condition and was afflicted by a strain of the virus called H1N1.
Also known as the swine flu, The H1N1 virus, was found in April 2009. According to health officials, people with weak immune systems are especially susceptible to the virus.
This season, 23 victims throughout the Bay Area's nine counties have died of flu-related illnesses.
Health officials recommend that everyone over the age of six months get an annual flu vaccine, which will help protect them against the H1N1 and H3N2 strains.
Oh, and don't forget to wash your hands -- a lot.
