Pertussis (Whooping Cough) Fact Sheet

What are the symptoms of pertussis infection?
Classic pertussis infections have three distinct phases of illness. The first stage, the catarrhal stage, is characterized by , runny nose, slight sore throat, and low grade or absent fever. This stage lasts one to two weeks.

emetic [umet'ik]
Pronunciation Key

emetic , substance that produces vomiting. Direct, or gastric, emetics, which act directly on the stomach, include syrup of ipecac, sulfate of zinc or copper, alum, ammonium carbonate, mustard in water, or copious quantities of warm saltwater. Indirect, or systemic, emetics, such as apomorphine, induce vomiting by acting indirectly through the blood on the brain center that controls vomiting. Emetics are not used to treat poisoning by strong acids or alkalis, petroleum distillates such as kerosene, or substances causing convulsions.

The cough progressively becomes more severe. The coughs may become spasmodic: a series of coughs so close together that the person cannot take a breath between coughs. Following the coughing spasms, there are gasps for air which may sound like a whoop. Vomiting (emmetic) may follow the coughing spasm. The spasmodic coughing marks the beginning of the second stage, the paroxysmal stage which may last two to four weeks.
