THURSDAY, Feb. 17 (HealthDay News) -- The flu season got off to a slow start in the United States last fall, but is now circulating in all 50 states and widespread in 37, health officials report.
Pediatric deaths from flu tripled in the past month, jumping from 10 early in January to 30 by Feb. 5, according to the U.S. Centers for Disease Control and Prevention.

Outpatient doctor visits because of flu increased steadily from January to February, according to the report in the Feb. 18 issue of the CDC's Morbidity and Mortality Weekly Report. The report covers the period from Oct. 3, 2010, to Feb. 5, 2011.
While it's too early for exact numbers, the flu, which usually peaks in February, contributed to 8 percent of adult deaths in 122 cities that report this data to the CDC. This is considered an epidemic level.

He added that "the number of hospitalizations and deaths are right on course for a typical flu season." Each year about 200,000 Americans are hospitalized and 37,000 will die from flu, Siegel said.
Skinner stressed that it's not too late to get a flu shot. "Flu activity is going to continue into March," he said. "There is plenty of vaccine out there, and we encourage vaccination throughout the season."
Of the three confirmed flu viruses -- influenza A H1N1, influenza A H3N2 and influenza B -- the H3N2 strain has predominated, but all three are circulating, according to the CDC report. The relative
