Pertussis is a contagious illness caused by bacteria. It occurs in infants and young children more often than older children and adults. Adults with milder, undiagnosed symptoms can transmit the disease to infants and children. Pertussis is usually spread by contact with an infected persons nose or throat secretions.
Immunization is the best way to prevent pertussis, said Staggs. We urge parents to be sure that their children are up to date on their diphtheria, tetanus, and pertussis (DTaP) series.
Pertussis can sometimes occur in children who have been immunized, but symptoms are normally milder than without immunization.
The first symptoms of pertussis are those of the common cold with a mild cough. After a week or two, the cough becomes worse and may occur more frequently during sleep. The cough then becomes paroxysmal (a series of five or ten coughs in a single breath), and usually ends with a whooping sound. Vomiting often occurs at the end of the coughing spell.
Antibiotics can be given to make an individual less contagious, but do not reduce the symptoms unless given very early in illness.
