Understanding Whooping Cough: Symptoms and Prevention
Whooping cough, or pertussis, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It primarily affects the respiratory tract and is characterized by severe coughing fits, which can lead to a distinctive "whooping" sound during inhalation after a cough.
What is Whooping Cough?
Whooping cough is caused by the bacterium Bordetella pertussis. The disease gets its name from the "whoop" sound that is often heard when the patient tries to breathe in after a severe coughing fit. Although it can affect individuals of all ages, it is particularly dangerous for infants and young children.

Get A Second OpinionSymptoms of Whooping Cough
Initial Symptoms
The initial symptoms of whooping cough are often mild and similar to those of a common cold. They include:
- Runny nose
- Nasal congestion
- Red, watery eyes
- Fever
- Cough
Progression
As the disease progresses, the symptoms become more severe and may include:
- Paroxysms of Coughing: Sudden, intense bouts of coughing that may last for minutes.
- Whooping Sound: A high-pitched "whoop" sound during the next breath of air.
- Vomiting: Coughing fits can be so severe that they trigger vomiting.
- Exhaustion: The intense coughing can lead to fatigue and exhaustion.
Symptoms in Infants
Whooping cough in infants can be particularly severe and life-threatening. Infants may not exhibit the classic cough and whoop but might instead have difficulty breathing or may even stop breathing temporarily.
Causes of Whooping Cough
Transmission
Whooping cough is highly contagious and spreads through respiratory droplets when an infected person coughs or sneezes. It can also spread by touching surfaces contaminated with the bacteria.
Risk Factors
Certain factors can increase the risk of contracting whooping cough:
- Age: Infants and young children are at higher risk.
- Vaccination Status: Individuals who are not vaccinated or are under-vaccinated are more susceptible.
- Close Contact: Living or spending time in close quarters with an infected person.
Diagnosis of Whooping Cough
Medical History and Physical Examination
A healthcare provider will start with a detailed medical history and physical examination. They will look for the characteristic symptoms and listen for the distinctive whooping sound.
Laboratory Tests
To confirm the diagnosis, the following tests may be conducted:
- Nasopharyngeal Swab: A sample is taken from the back of the throat and tested for Bordetella pertussis.
- Blood Tests: To check for elevated white blood cell counts, which indicate infection.
Complications of Whooping Cough
In Infants
Complications in infants can be severe and may include:
- Pneumonia
- Seizures
- Brain damage
- Death
In Older Children and Adults
While generally less severe, complications in older children and adults can still occur and may include:
- Rib fractures from severe coughing
- Abdominal hernias
- Urinary incontinence

Book an AppointmentTreatment of Whooping Cough
Antibiotics
Antibiotics are the primary treatment for whooping cough. They are most effective when administered during the early stages of the disease. Antibiotics can help prevent the spread of the infection to others but may not alleviate the symptoms in the later stages.
Supportive Care
Supportive care focuses on relieving symptoms and may include:
- Hydration: Ensuring adequate fluid intake to prevent dehydration.
- Rest: Getting plenty of rest to help the body recover.
- Hospitalization: Severe cases, especially in infants, may require hospitalization for more intensive care, such as oxygen therapy or intravenous fluids.
Prevention of Whooping Cough
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:
- Hand Washing: Regular and thorough hand washing with soap and water.
- Cough Etiquette: Covering the mouth and nose with a tissue or elbow when coughing or sneezing.
- Cleaning Surfaces: Regularly cleaning and disinfecting frequently touched surfaces.
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.

Symptoms include a severe, persistent cough, difficulty breathing, and a characteristic "whooping" sound when inhaling after a coughing fit.
3. How is whooping cough treated?
Treatment includes antibiotics like azithromycin or erythromycin to reduce the severity and prevent transmission to others.
4. How is whooping cough prevented?
Vaccination is the primary method of prevention, with booster shots recommended for adults and adolescents.
5. What are the complications of whooping cough in infants?
Complications include pneumonia, seizures, brain damage, and, in severe cases, death, especially in unvaccinated infants.
