Hospitalist Laura Romano, D.O., explains the key facts about pertussis (whooping cough) and the vaccine that prevents it.

What is pertussis?

Pertussis, a highly contagious bacterial infection, causes a severe, long-lasting cough which can sometimes end in a "whooping" sound when a child breathes in. The illness is also known as whooping cough or the “100-day cough.”

In older children and adults, pertussis typically causes only a low-grade fever and a prolonged cough. However, the disease can be fatal in infants. In babies, pertussis can cause difficulty breathing, apnea (when a baby stops breathing) due to coughing and respiratory failure. The infection can be fatal even when treated with antibiotics.

How can the disease be prevented?

Pertussis is very contagious. Vaccinating newborns is the best way to protect them. New parents, grandparents, or aunts and uncles should also receive a Tdap vaccine before welcoming a new baby home.

As a medical community, we have watched pertussis vaccination rates steadily decline in recent years, leading to outbreaks in states like Kentucky. In that outbreak, three babies died from respiratory failure. Pertussis has proven to be fatal to at-risk infants and unvaccinated children.
