How is pertussis spread?
Transmission occurs from person to person when germs pass from an infected person into the nose or throat of others. Pertussis can be transmitted by direct contact or through the air. Pertussis is highly infectious (easy to spread) and can infect up to 70 - 100% of close household contacts who have not received all of their vaccinations.
