Flu-related emergency room activity increases at San Diego hospitals

An increase in emergency room activity at local hospitals shows that flu season is not over.

In its weekly influenza report, the county Health and Human Services Agency states that 6 percent of local emergency department cases showed flu-like symptoms last week, a rate not seen since the final days of December.

Dr. Eric McDonald, medical director of the county’s epidemiology and immunization services branch, said Wednesday that emergency cases have continued at similar, or perhaps even slightly worse, rates this week. While H1N1-type flu viruses continue to be the most common sources of infection, McDonald noted that H3N2 viruses have become the most prevalent in many parts of the country, especially the southeastern states.
