Written by Medicover Team and Medically Reviewed by Dr Ashritha Rao Komandla , Pediatricians

Whooping Cough, also known as pertussis, is a highly contagious bacterial infection of the respiratory tract caused by Bordetella pertussis. It is characterized by severe coughing fits that may be followed by a high-pitched "whooping" sound when breathing in. Symptoms often begin like a common cold and can progress to prolonged coughing episodes, fatigue, and breathing difficulties. Early diagnosis and treatment with antibiotics can help reduce symptoms, prevent complications, and limit the spread of infection.

How Can Whooping Cough Be Prevented?

Prevention mainly relies on vaccination and reducing exposure to infection. Public health measures and good hygiene also help limit transmission.

Vaccination

Vaccination is the most effective way to prevent whooping cough. The DTaP (diphtheria, tetanus, and pertussis) vaccine is recommended for infants and children, while the Tdap booster is recommended for adolescents and adults.

Pregnant women are also advised to receive the Tdap vaccine during each pregnancy to protect their newborns.

Hygiene Practices

Good hygiene practices can help reduce the spread of whooping cough:

Quarantine

Infected individuals should stay home from work, school, or daycare until they have completed at least five days of antibiotic treatment to prevent spreading the disease to others.

What is the Recovery Process for Whooping Cough?
