Pertussis, commonly known as whooping cough, is primarily caused by the infection of Bordetella pertussis. The main transmission routes are through the respiratory tract or via close contact, particularly in classrooms where young children are present, which can easily lead to cross-infection. The disease has an incubation period of about three to seven days, and in some cases, it can range from two to three weeks. Children under the age of five have the highest incidence rate. Clinically, vaccination is recommended for prevention. Once infected, the early stages of the disease resemble those of a common cold, with typical symptoms being paroxysmal, spasmodic coughing.
