Pertussis may clear up on its own in resistant patients without complications, but it can last longer.
As pertussis mostly infects infants and young children, who are not yet immune, it is difficult for them to heal on their own.
In addition, paediatric patients are prone to complications such as pneumonia, pneumothorax, pulmonary consolidation, apnoea, pertussis encephalopathy, seizures and intracranial haemorrhage, which can lead to asphyxia or even death in severe cases.
Pertussis is highly contagious and spreads through the respiratory tract, and if left untreated, can cause other children to contract the disease.
In summary, it is important to seek prompt medical attention after the onset of symptoms associated with whooping cough. Prompt treatment will not only shorten the duration of the illness and reduce complications, but will also reduce the chance of transmission to others.
