pertussis diagnosis

Diagnosing pertussis, or whooping cough, involves reviewing a person's medical history and symptoms, such as severe coughing fits and a whooping sound. A healthcare provider may perform a physical exam and order lab tests, like a nasal swab or blood test, to detect the bacteria Bordetella pertussis. These tests can confirm the infection, especially if taken early. Early diagnosis is important to manage symptoms and prevent spreading the infection to others, particularly vulnerable infants and unvaccinated individuals.
