Pertussis
Pertussis, commonly known as whooping cough, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. It spreads easily from person to person through droplets when an infected individual coughs or sneezes. The infection is characterized by severe coughing fits that can interrupt breathing and cause a “whooping” sound when the person breathes in deeply afterward.
Symptoms of pertussis usually start with mild signs similar to a common cold, such as a runny nose and mild cough. As the condition progresses, the cough becomes more severe, leading to coughing spells that can last weeks or even months. These symptoms are often more severe in infants and young children.
Vaccination is the most effective way to prevent pertussis. In Australia, the pertussis vaccine is typically given as part of the childhood immunization program. Booster doses are often recommended for adolescents and adults to maintain immunity and protect those who are vulnerable, such as infants who are too young to be vaccinated. Early diagnosis and treatment are crucial to managing the spread and reducing the severity of the illness.
