Whooping Cough (Pertussis)

Whooping cough (pertussis) is a highly contagious bacterial respiratory disease caused by the bacterium Bordetella pertussis. It is spread through droplets when a person coughs, sneezes, or comes into close contact with an infected person. The risk of infection exists worldwide, and in recent years, the disease has been reappearing more frequently in Europe, including the Czech Republic.

The disease initially resembles a common cold; later, bouts of persistent coughing develop, which can last from several weeks to months. The cough is often accompanied by vomiting, exhaustion, or a characteristic gasping sound after a coughing fit. The most severe course of the disease is seen in infants, who may experience respiratory arrest, pneumonia, or serious neurological complications. In adults, the disease is often the cause of a persistent cough and can be a source of infection for young children.

Immunity following vaccination or after recovering from the disease is not lifelong and gradually weakens. Therefore, regular booster shots with the combined vaccine against tetanus, diphtheria, and pertussis are recommended, especially for adults, pregnant women, healthcare workers, and people who come into contact with infants. A booster shot before traveling is especially recommended if more than 10 years have passed since the last dose.
