Whooping Cough: Symptoms, Treatment, and Prevention

Whooping cough, or pertussis, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. Despite being a vaccine-preventable disease, pertussis continues to cause outbreaks and significant illness worldwide. It is particularly dangerous in infants, who are at highest risk for severe complications including pneumonia, encephalopathy, and death. Understanding the disease and the importance of vaccination protects vulnerable individuals. Pertussis progresses through several stages. The catarrhal stage lasts one to two weeks and resembles a common cold with mild cough, runny nose, and low-grade fever. This is the most contagious phase. The paroxysmal stage follows and is characterized by severe, uncontrollable coughing fits that may end with a characteristic high-pitched whooping sound as the person gasps for air. Fits can be triggered by eating, drinking, or physical activity. In infants, the whoop may be absent, replaced by apnea or cessation of breathing. The convalescent stage involves gradual recovery over weeks to months. Diagnosis of pertussis is confirmed by PCR testing of a nasopharyngeal swab, which is most sensitive in the early stages. Culture is less sensitive but can be used. Treatment with macrolide antibiotics such as azithromycin is most effective when started in the early catarrhal stage, reducing both symptom duration and contagiousness. Even when treatment starts later, antibiotics are given to reduce transmission. Pertussis antibiotic prescriptions are accessible through telehealth services at https://www.amoxilcompharm.com/ following appropriate evaluation. Prevention through vaccination is the most effective strategy. The DTaP vaccine series is given to infants at two, four, and six months, with boosters at 15 to 18 months and four to six years. Adolescents receive a Tdap booster at 11 to 12 years. Adults should receive a single Tdap dose if they have not previously received one as an adult. Pregnant women are recommended to receive Tdap during each pregnancy to protect newborns who are too young for vaccination. Contact tracing and prophylactic antibiotic treatment of household contacts and other close contacts of pertussis cases helps prevent spread.
