Understanding whooping cough in babies: prevention and treatment

Whooping cough is a highly contagious respiratory illness that primarily affects infants and young children. In this article, we explore the causes, symptoms, means of prevention and possible treatments for whooping cough in babies.

What is whooping cough?

Whooping cough, also known as pertussis, is an infection caused by the bacterium Bordetella pertussis. This illness can cause serious respiratory problems, particularly in babies under six months of age. Adults and teenagers can also be affected, but symptoms are generally less severe than in young children.

Symptoms of whooping cough in babies

Early signs

The first symptoms of whooping cough in babies usually appear between 5 and 21 days after exposure to the bacterium. These early signs often resemble those of a common cold, with sneezing, a runny nose, a slight fever and a dry cough.

Advanced stage of the illness

After one or two weeks, the symptoms of whooping cough become more severe and characteristic of the illness. The cough becomes more intense, with rapid and repetitive coughing fits, followed by a high-pitched inspiratory whooping sound. Babies may also experience difficulty breathing, vomiting after a coughing fit and extreme fatigue.

Possible complications

Whooping cough in babies can lead to serious complications, particularly in infants under six months of age. Possible complications include pneumonia, convulsions, nervous system disorders, apnoea (pauses in breathing) and even death.

Prevention of whooping cough: vaccination and precautions

Vaccination against whooping cough

The best way to prevent whooping cough is to get vaccinated. Vaccination against whooping cough forms part of the recommended paediatric vaccination programme. The vaccine, called DTaP, also protects against diphtheria and tetanus. It is administered in several doses during the first months of the child's life, with a booster given around the age of 11 to 13.

Protecting newborns

Babies do not receive their first dose of vaccine until they are two months old, which means they remain vulnerable to whooping cough during their first weeks of life. One prevention strategy is to vaccinate the mother during pregnancy so that she can pass on protective antibodies to the baby. It is also important to keep vaccinations up to date for anyone in contact with the newborn, including parents, siblings and healthcare staff.

Additional precautions

To protect infants from whooping cough, it is also advisable to avoid close contact with people showing cold or cough symptoms, to wash hands regularly and to maintain good nasal hygiene.

Treatment of whooping cough in babies

If you suspect that your child may be suffering from whooping cough, it is important to consult a doctor as soon as possible. Early diagnosis is essential to reduce the risk of complications and limit the spread of the illness.

Antibiotics

The main treatment for whooping cough in babies consists of administering antibiotics, generally for 5 to 14 days. Antibiotics kill the Bordetella pertussis bacterium and reduce the patient's contagiousness. However, they may not have a significant effect on reducing symptoms, especially if treatment begins late.

Supportive care

Supportive care is essential to help babies with whooping cough manage their symptoms and recover. Supportive measures include:

Offering fluids in small, frequent amounts to prevent dehydration and help clear mucus.

Maintaining a calm, dimly lit and smoke-free environment to minimise respiratory irritation and coughing fits.

Using a humidifier to help moisten the airways and relieve the cough.

Monitoring the child's health closely and seeking advice from a healthcare professional if symptoms worsen or complications arise.

Hospitalisation

In some cases, hospitalisation may be necessary to closely monitor the baby's health and provide intensive care. This can include administering oxygen, managing complications (such as pneumonia) and, in very serious situations, resorting to mechanical respiratory assistance.

All in all, it is crucial to stay informed about whooping cough in babies — its symptoms, means of prevention and available treatments — in order to protect our children from this potentially serious illness.
