A37.0: Whooping cough due to Bordetella pertussis

You have whooping cough.

Whooping cough is caused by bacteria. At the start of the illness, you usually feel somewhat ill. You may have a fever, sore throat and sniffling. After one or two weeks, a severe cough develops. This cough is spasmodic and can cause severe breathing difficulties. These fits of coughing occur repeatedly. It is possible to breathe normally between the coughing attacks. Small blood vessels in the eyes may burst as a result of the severe coughing. As a result, the eyes may appear red.
