Whooping Cough (Pertussis)

Whooping cough is an infection caused by bacteria. It starts with a runny nose and cough that soon becomes more frequent and severe.

Whooping cough is most severe in infants less than one year of age. Pregnant women in the last three months of their pregnancy are also high risk because they can pass the infection on to their newborn baby.

Whooping cough spreads easily from person to person through the air by coughing. Immunization is the best way to prevent it. If someone is already sick with whooping cough, early treatment with antibiotics will prevent it from spreading to others and may help the cough get better.
