Swine flu sends many to ICU

A quarter of Americans sick enough to be hospitalized with swine flu last spring wound up needing intensive care and 7 percent of them died, the first such study of the early months of the global epidemic suggests.

That's a little higher than with ordinary seasonal flu, several experts said.

What is unusual is that children and teens accounted for nearly half of the hospitalized cases, including many who were previously healthy. The study did not give a breakdown of deaths by age.

The study was conducted by researchers at the U.S. Centers for Disease Control and Prevention, working with hospitals and state and local health departments. Results were published online Thursday by the New England Journal of Medicine.

Researchers led by the CDC's Dr. Seema Jain identified 272 patients hospitalized for at least a day from April through mid June, when the virus caused its first wave of cases. That's about one-fourth of the total hospitalizations for swine flu reported during that time, but researchers only studied lab-confirmed cases and patients who agreed to be part of the study.

Three-fourths of these patients had other health problems, such as diabetes — typical of seasonal flu, too. However, only 5 percent were 65 and older; ordinary seasonal flu usually hits hardest in the elderly.

Seven percent were pregnant, even though pregnant women make up only 1 percent of the general population. Among hospitalized patients whose weight was known, 26 percent were very obese, confirming a risk factor suggested by other information from the outbreak.

First death in Pasco; seventh in Pinellas

Pasco County has marked its first fatality from swine flu, a 35-year-old man whose death was announced Thursday but who officials said died about two weeks ago. Meanwhile, Pinellas County health officials on Thursday announced that county's seventh H1N1 flu death, a 50-year-old woman with "underlying health conditions." In the Pasco case, officials did not have information on the man's health before he contracted the virus. The Florida Department of Health has launched a toll-free number to provide public health information and updates on H1N1 swine flu. The toll-free information line at 1-877-352-3581 is available from 8 a.m. to 8 p.m., seven days a week.
