Pertussis, commonly known as whooping cough, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. It is characterized by severe coughing fits that can last for weeks or even months. The name "whooping cough" comes from the high-pitched "whoop" sound that often follows a coughing fit, as the person tries to catch their breath. This sound is more common in children than adults.

The disease is particularly dangerous for infants and young children, as it can lead to complications such as pneumonia, convulsions, and even death. In adults and older children, pertussis can cause severe coughing fits that can interfere with daily activities and lead to rib fractures or fainting. The symptoms of pertussis typically develop within 5 to 10 days after exposure to the bacterium and can include runny nose, sneezing, mild cough, and low-grade fever, followed by severe coughing fits.

Pertussis is spread through respiratory droplets when an infected person coughs or sneezes. It is highly contagious, and people can spread the disease to others before they even know they are infected. The best way to prevent pertussis is through vaccination. The DTaP vaccine is given to children in a series of shots, while the Tdap vaccine is recommended for adolescents and adults to protect against pertussis, tetanus, and diphtheria.

Treatment for pertussis usually involves antibiotics, which can reduce the severity and duration of the illness if given early in the course of the disease. However, antibiotics are not always effective in treating the cough, which can persist for weeks or months. Supportive care, such as rest, fluids, and over-the-counter medications to relieve symptoms, can also be helpful. In severe cases, hospitalization may be required.
