Saint Louis County is seeing a surge in cases of pertussis.

More commonly known as “whooping cough,” pertussis is highly contagious, spreading through the air via small droplets when infected people cough, sneeze or talk.

One hundred and eighty-five cases have been reported in the county so far this year – two-thirds of them in the past six weeks.
