whooping cough

The number of whooping cough cases in Utah has reached a level not seen for more than 60 years.  The State Department of Health says there have been 851 cases of pertussis reported so far this year.  The number of people with the bacterial disease already exceeds the total in 2006 when the last notable outbreak occurred.  Health experts don’t know why Utah and the nation are seeing the worst outbreak of the disease in decades.
