You may have heard about the recent epidemic of whooping cough in the news, and like most parents probably have many questions. Pertussis (also know as “whooping cough”) is a respiratory illness that is characterized by paroxysms of cough. Vaccinations greatly decrease the incidence of the disease, although we do see some cyclical peaks in activity.

Infants and young children are the most severely affected, and it can be fatal especially in young infants.

A normal incubation period for the illness is about 7 to 10 days, but may be shorter or longer. After this, the symptoms start to appear.
