CHEYENNE, Wyo. — Cases of whooping cough are up dramatically in Wyoming this year.

Last year, Wyoming had 13 cases of whooping cough. So far this year, the number is up to 36.
The outbreak is nationwide. Across the United States, more than twice as many cases have been reported so far this year, with the biggest increases occurring in the Mid-Atlantic, Upper Midwest and West Coast states.
Whooping cough is an upper respiratory infection that's especially dangerous to infants and young children. Cases of the disease tend to peak every two to five years.
