The Centers for Disease Control considers whooping cough, also known as pertussis, a highly contagious respiratory disease. which causes uncontrollable, violent coughing which often makes it hard to breathe.

"After fits of many coughs, someone with pertussis often needs to take deep breaths which result in a 'whooping' sound. Pertussis can affect people of all ages, but can be very serious, even deadly, for babies less than a year old," writes the CDC.

The best prevention against whooping cough is the vaccine DTap, combination vaccine that helps protect against three diseases: diphtheria, tetanus and pertussis. according to the CDC.

Symptoms are often cold-like and begin with a mild cough or fever and can include a runny nose, low-grade fever and a a mild, occasional cough. In babies, it can cause a pause in breathing called an apnea, according to the CDC. The fits of coughing, vomiting and exhaustion after the coughing fits come as the disease progresses. Recovery from whooping cough is slow.
