TOPEKA – Kansas has joined several states this year in identifying an increase of pertussis cases (also known as whooping cough).

Fifty-six confirmed cases have been reported to the Kansas Department of Health and Environment (KDHE) as of June 11. In 2011, only 52 confirmed cases were reported for the entire year.

During 2011 and 2012, KDHE and local health departments have investigated eight outbreaks, including the ongoing outbreak in Johnson County.

KDHE  encourages everyone, including adults, to check with their health care provider on their vaccination status and to get vaccinated if not up to date.

Whooping cough is a highly contagious bacterial respiratory illness spread by coughing and sneezing.  It causes cold-like symptoms followed by a long, severe cough that can last for weeks.
