How Is Pertussis Spread?

Find out how it spreads and when adults and children are most contagious

Bacteria that are found in the nose and throat of an infected person cause pertussis. It is spread from one person to another through close contact, when an infected person talks, sneezes, or coughs. It is most contagious during the first weeks of infection, before the severe coughing begins.1,2,3

Pertussis is one of the most contagious human diseases, so it is a great risk to children who are not vaccinated. Parents, caregivers, and older siblings can spread the disease to infants and young children in the same household. Schools and day care centers are also a common source of infection for older children and adolescents.1,2,3

Recently, mild pertussis has been identified as an important contributor to the pool of infection and the continued spread of the disease. Mild pertussis is less severe than the classic disease, and it is difficult to diagnose because it lacks the classic whooping cough. Therefore, it is often mistaken for a bad chest cold or bronchitis, particularly in adolescents and adults. However, mild pertussis is still highly contagious and very dangerous. Infected adults and adolescents can pass mild pertussis to infants and young children, where it can cause severe disease and serious complications.1,2

Since pertussis is most contagious in adults and children before it's diagnosed, vaccination is the best way to protect your baby. Make an appointment with your child's doctor today and ask about DAPTACEL vaccine.
