San Mateo County reported another flu-related death Wednesday, bringing its total to four and the nine-county region’s overall total to 29.
All four of the local deaths involved individuals under the age of 65 and three had underlying medical conditions, according to the San Mateo County Health System.
Three cases were confirmed as strains of the H1N1, or so-called swine flu, and the fourth remains unidentified.
The county has also seen 10 flu-related ICU hospitalizations.
On Wednesday, San Francisco and Sonoma counties also reported one new death each. Of the entire Bay Area region, Santa Clara County has the highest death total of six.
San Mateo County has no shortage of the flu vaccine and continues encouraging residents to get vaccinated, said Health System spokeswoman Robyn Thaw.
The vaccine takes about two weeks after inoculation to be fully effective, according to health officials.
There were five other flu-related deaths in the Bay Area reported Wednesday in San Francisco, Sonoma and Contra Costa counties.
Three additional deaths in Contra Costa County have been linked to the flu this month, county health services officials said. Five people younger than 65 have died since December, health officials said.
The new Contra Costa cases were a man in his 30s, a man in his 50s and woman in her 60s. The first two deaths were a man and a woman both in their 40s.
There have been 30 flu-related deaths this season throughout the Bay Area region.
