DETROIT (WWJ) – This week has been a particularly deadly one for the flu. Seven children died across the U.S. — bringing the total number of pediatric deaths this season to 37, according to the U.S. Centers for Disease Control.

Young children and the elderly are at the greatest risk from flu and its complications; and this year, officials say, baby boomers have been the hardest-hit group.

Health Commissioner and infectious disease specialist Dr. DeborahMcMahon sent out a warning Friday urging people to take care of themselves and get a flu shot.

Her instructions are simple:

“I’m not asking you to prep for a marathon, I’m not asking anything like that,” McMahon said in a CBS News Radio report, which ailed on WWJ. “Get a flu shot, wash your hands, don’t go to work if your sick, call a doctor with Tamiflu.”
