A prolonged post-viral cough affecting thousands of people has emerged as a growing health concern, with doctors reporting symptoms that can persist for three to eight weeks even after recovery from common respiratory infections.
Health experts say the condition is being triggered by a range of respiratory viruses, including seasonal flu and other viral infections, leading to irritation and hypersensitivity of the airways long after the acute illness subsides.
Why the cough lasts so long
Doctors explain that post-viral cough occurs when inflammation in the respiratory tract takes time to heal. Even after fever and cold symptoms resolve, the airways may remain sensitive, causing frequent bouts of dry or productive coughing.
Medical professionals stress that in most cases, the condition is not serious and gradually improves without aggressive treatment. However, exposure to dust, cold air, smoke, or strong smells can worsen symptoms and prolong recovery.
When medical attention is needed
While the majority of patients recover with rest and supportive care, doctors advise seeking medical review if the cough persists beyond eight weeks or is accompanied by symptoms such as breathlessness, chest pain, blood in sputum, or unexplained weight loss.
Children, elderly individuals, and those with asthma or chronic lung conditions are advised to be especially cautious, as post-viral cough may aggravate underlying respiratory issues.
Treatment and prevention tips
Doctors recommend staying well hydrated, avoiding irritants, and using prescribed cough suppressants or inhalers when advised. Self-medication with antibiotics is strongly discouraged, as post-viral coughs are not caused by bacterial infections.
With changing weather patterns and increased viral circulation, health officials are urging people to practise respiratory hygiene, wear masks when symptomatic, and allow adequate recovery time after viral illnesses.
Experts emphasise that patience is key, reassuring patients that post-viral cough, though frustrating, is usually temporary and manageable with proper care.
