Also known as: Pertussis
Whooping cough is a highly contagious respiratory infection caused by Bordetella pertussis bacteria, characterized by severe coughing fits that may end with a high-pitched 'whoop' sound. It can be life-threatening in infants.
Pertussis remains a significant global health concern, with an estimated 24 million cases and 160,000 deaths annually, primarily in infants under 6 months. Despite widespread vaccination, pertussis has not been eliminated due to waning vaccine immunity.
The illness progresses through three stages: the catarrhal stage (1-2 weeks of cold-like symptoms, when the person is most contagious), the paroxysmal stage (2-8 weeks of severe coughing fits), and the convalescent stage (gradual recovery over weeks to months).
In infants, the classic 'whoop' may be absent — instead, they may present with apnea (pauses in breathing) and cyanosis (turning blue). This makes early recognition and treatment critical.
Vaccination with DTaP (children) and Tdap (adolescents, adults, and pregnant women) is the primary prevention strategy. Maternal vaccination during each pregnancy (ideally at 27-36 weeks) provides passive antibody protection to newborns.
People with Whooping Cough often experience the following symptoms.
Uncontrollable fits of rapid coughing followed by a gasping 'whoop' as the person tries to inhale. Fits may occur dozens of times per day and can be triggered by eating, drinking, or activity.
Vomiting at the end of coughing fits is common, particularly in children. This may lead to dehydration and weight loss.
The initial 1-2 weeks resemble a common cold with runny nose, mild cough, and low-grade fever. This is the most contagious period and is often indistinguishable from other upper respiratory infections.
Young infants may not develop the typical whoop but instead exhibit pauses in breathing (apnea) and episodes of turning blue (cyanosis), which can be life-threatening.
Certain factors may increase your likelihood of developing Whooping Cough.
Common approaches to managing whooping cough. Always consult a healthcare provider for personalized treatment.
Azithromycin, erythromycin, or clarithromycin are the standard treatment. Most effective when started during the catarrhal stage. They reduce contagiousness but may not shorten symptoms if started after paroxysms begin.
Rest, small frequent meals, adequate hydration, and a calm environment to reduce coughing triggers. Humidified air may provide some comfort.
Infants under 6 months often require hospitalization for monitoring of apnea, supplemental oxygen, suctioning of secretions, and IV fluids.
Close contacts (especially household members and infants) should receive prophylactic antibiotics regardless of vaccination status to prevent secondary transmission.
Nasopharyngeal swab for PCR testing is the preferred diagnostic method. Culture is highly specific but less sensitive. Serology (anti-pertussis toxin IgG) is useful for later-stage diagnosis. A persistent cough lasting more than 2 weeks with paroxysms should raise clinical suspicion.
Seek emergency care for infants with any cough illness, and for anyone with coughing fits that cause vomiting, turning blue, or difficulty breathing. Whooping cough can be fatal in babies under 12 months.
Steps that may help reduce the risk of developing or worsening whooping cough.
DTaP vaccine series for children (5 doses by age 6)
Tdap booster for adolescents at age 11-12
Tdap vaccination during each pregnancy (27-36 weeks)
Prophylactic antibiotics for close contacts of confirmed cases
If left untreated or poorly managed, whooping cough may lead to:
The full illness may last 6-10 weeks or longer. The paroxysmal coughing stage typically lasts 2-8 weeks, and recovery is gradual. It is sometimes called the '100-day cough.'
Yes. Vaccine immunity wanes over time, and adults may develop pertussis with a persistent, severe cough without the classic whoop. They can unknowingly transmit it to vulnerable infants.
Infants under 6 months have immature airways and immune systems. They may not cough effectively and can develop apnea, pneumonia, and brain damage. Most pertussis deaths occur in this age group.
