A type of flu particularly dangerous for the very old and very young is making its way through Sonoma County.
With flu season expected to ramp up this month, local public health officials are urging Sonoma County residents 6 months and older to get a flu shot to curb the spread of the virus.
Infectious disease experts say this year’s dominant strain could be Influenza A’s H3 subtype, a particularly virulent virus. Early cases of H3 flu virus have been detected in various parts of the country. People who contract the H3 subtype are going to become more severely ill, get higher fevers, a longer period of illness and in some cases, more severe pneumonia following the flu.
