The first flu-related death of the season in San Mateo County was reported Thursday, according to county health officials.
A woman in her 40s died after contracting the flu, and there have been six other flu-related hospitalizations in the county, health officials said.
The H1N1 influenza strain, known as “swine flu” when it first emerged in 2009, appears to be the main strain afflicting people this flu season.
Peak flu season is between January and March.
Health officials are urging vaccinations for everyone ages 6 months and older. This year’s vaccine protects against H1N1.
