Whooping cough (a bacterial infection that causes severe coughing fits and can be serious, especially in young children) cannot be effectively treated with regular cough syrups and requires proper medical care. Over-the-counter medicines usually do not help and may sometimes make symptoms worse, so it is crucial to consult a qualified doctor who can recommend the safest and most effective treatment. Supportive care, such as staying hydrated and resting, is also essential, and keeping vaccinations up to date helps prevent whooping cough in the future.
