Whooping cough is a bacterial respiratory infection characterized by violent coughing fits that can affect the lung and airways, most commonly seen in infants and young children.
What causes whooping cough?
The infection is caused by a bacterium called Bordetella pertussis, which attaches to the cilia lining the respiratory tracts. This leads to inflammation and swelling in these passages, causing a cough and cold-like symptoms.
Symptoms and stages of whooping cough
Signs usually appear 6 to 20 days after infection and progress through three main stages:
- Catarrhal stage: Lasts one to two weeks, featuring mild symptoms such as a runny or congested nose, a slight cough, and a low-grade fever.
- Paroxysmal stage: Lasts one to 10 weeks, characterized by rapid, successive coughing fits followed by a deep inhalation sound that resembles a rooster’s crow. This may be accompanied by vomiting, extreme exhaustion, or bluish skin.
- Convalescent stage: Coughing fits gradually decrease; this period can last from one week to 3 months.
In infants, severe coughing may not occur; instead, the infection may manifest as apnea (paused breathing) and facial cyanosis. Adults who were previously vaccinated typically experience milder symptoms.
Is whooping cough contagious?
Yes, it is highly contagious. It spreads via:
- Inhaling droplets from the sneeze or cough of an infected person.
- Touching surfaces contaminated with droplets and then touching the nose or mouth.
- Direct contact with infected individuals.
A person is contagious from the sixth day of the first stage’s symptoms until 3 weeks after the cough begins. Antibiotics may help reduce this contagious period.
How is whooping cough diagnosed?
Early detection can be difficult because it resembles the flu. Therefore, doctors rely on:
- Medical history and physical examination: Listening for the characteristic cough sound using a stethoscope to assess the lung.
- Throat culture: Taking a swab from the area where the nose meets the throat.
- Additional tests: These include blood tests to check white blood cells or chest X-rays to detect fluid or pneumonia.
Treatment options for whooping cough
Care varies based on age and condition:
- Antibiotics: Such as erythromycin, which is the primary treatment to reduce the infectious period and prevent spread, although they may not stop the cough if started late.
- Hospital care: Infants often require hospitalization for monitoring and may receive intravenous fluids to prevent dehydration or oxygen to assist breathing.
- Other medications: Doctors may prescribe corticosteroids for severe cases in children.
- Assistive devices: Using a nebulizer to soothe the respiratory passages and break up secretions.
Note: Expectorants or cough suppressants are ineffective in this case.
Home care tips
- Complete rest in a quiet, cool room.
- Drink plenty of fluids (water, natural juices, soup) to avoid dehydration.
- Eat small, frequent meals to reduce the likelihood of vomiting.
- Avoid irritants such as tobacco smoke and stove fumes.
Is whooping cough dangerous?
Yes, especially for infants under 6 months, as it can lead to complications such as pneumonia, seizures, kidney failure, or brain damage due to lack of oxygen.
In adults and older children, the danger lies in the strain caused by violent coughing, which may cause:
- Rib fractures or cracks.
- Abdominal wall hernias.
- Nosebleeds or ruptured small vessels in the white of the eye.
- Urinary incontinence.
Risks increase for pregnant women, people with diabetes, and those with weakened immunity.
Prevention and immunization
Vaccination is the primary means of prevention. Children receive the acellular pertussis vaccine at 2, 4, and 6 months, with booster doses at 15-18 months, 4-6 years, and 11 years.
Vaccination is also recommended for pregnant women between 27 and 36 weeks of pregnancy to protect newborns, as well as for adults over 65 and childcare workers.
FAQ
Is whooping cough contagious?
Yes, it spreads easily through respiratory droplets or by touching contaminated surfaces.
Is whooping cough dangerous?
It is considered very dangerous for infants and can cause death or brain damage, while it causes physical strain and mechanical complications for adults.
How can I protect my child?
By adhering to the routine vaccination schedule and booster doses, and maintaining hand hygiene.
When to visit a doctor?
Seek medical care immediately if the following signs appear:
- Coughing fits that cause the face or skin to turn blue.
- Severe difficulty breathing or apnea.
- Persistent vomiting that prevents the child from keeping down fluids and food.
