Whooping cough cases in the United States have surged to the highest levels in a decade, with no sign of a slowdown, according to the CDC. The federal health agency reports that cases this year are six times higher than at the same time last year.
Pertussis, also known as whooping cough, is highly contagious and often begins with cold-like symptoms before developing into a severe cough that can last for months. Children under the age of 1 are most at risk, and the CDC strongly recommends the DTaP vaccine for infants to protect against the disease.
