Early, Severe Flu Season Caused Big Rise in Child Deaths: CDC
Senior hospitalizations also up during 2012-13 onslaught, U.S. health officials say
By Steven Reinberg
THURSDAY, June 13 (HealthDay News) -- This past flu season started earlier, peaked earlier and led to more adult hospitalizations and child deaths than most flu seasons, U.S. health officials reported Thursday.
At least 149 children died, compared to the usual range of 34 to 123, according to the U.S. Centers for Disease Control and Prevention.
The predominant strain of flu circulating in 2012-13 -- H3N2 -- made the illness deadlier for children, explained Lynnette Brammer, an epidemiologist with the CDC.
"With children H3 viruses can be severe, but there was also a lot of influenza B viruses circulating . . . and for kids they can be bad, too," she said.
Dr. Marc Siegel, an associate professor of medicine at NYU Langone Medical Center in New York City, added that H3N2 is easily transmitted from person to person and has a high rate of complications, which accounts for the increased hospitalizations.
"This is the kind of flu that enables other infections like pneumonia," he said. "Really what people need to know is that flu isn't the problem. The flu's effect on the immune system and fatigue is the problem."
The flu season started in September, which is unusually early, and peaked at the end of December, which is also unusual, Siegel said.
Flu season typically begins in December and peaks in late January or February.
Texas, New York and Florida had the most reported pediatric deaths. Except for the 2009-10 H1N1 flu pandemic, which killed at least 348 children, the past flu season was the deadliest since the CDC began collecting data on child flu deaths, according to the report, published in the June 14 issue of the Morbidity and Mortality Weekly Report.
Older adults were targeted heavily by the 2012-13 flu. Those aged 65 and older accounted for more than half of all reported flu-associated hospitalizations in the 2012-13 flu season -- the most since the CDC started collecting data on flu hospitalizations in 2005-06, the agency reported.
In addition, more Americans saw a doctor for flu than in recent flu seasons, the CDC noted.
