Pertussis - also known as "whooping cough" - is a very contagious respiratory illness caused by a type of bacteria called Bordetella pertussis. The bacteria spreads through respiratory droplets created when an infected individual coughs, sneezes, or speaks. Symptoms typically appear 5-10 days after exposure but can develop up to 21 days after exposure. Symptoms range from mild illness with low-grade fever and occasional coughing in the early stage, to vomiting, exhaustion, and severe fits of rapid coughing in the later stage. Infants and children up to 4 years old are at highest risk and typically suffer the most severe symptoms.
