Nearly 800 In California Hospitalized With H1N1 Flu

Nearly 800 people in California were hospitalized with the H1N1 flu last week, the largest one-week number of hospitalizations since flu cases began escalating this fall, state officials said Thursday.

The number indicates that H1N1 flu, also known as swine flu, continues to be widespread throughout California and remains a significant threat to public health. Health experts have said there could be a second wave of cases in the coming months.
