Whooping cough, scientifically known as pertussis, is a highly contagious respiratory disease that causes violent coughing fits. Some other commonly used synonyms for whooping cough include "100-day cough" due to its long-lasting nature, "pertussis" which is its medical name, and "the cough of 100 days" referring to the duration of the coughing fits. The condition is often referred to as "the cough with a whoop" because of the distinctive sound made during coughing fits. Other descriptive words used for whooping cough include debilitating, paroxysmal, spasmodic, and suffocating. Regardless of the terminology used, early diagnosis and treatment are important to prevent potential complications. Vaccination is the best way to protect against this infection.
