Karachi is experiencing a notable rise in influenza cases, driven by the spread of the H3N2 strain, prompting doctors to urge vaccinations and caution among the public. Hospitals in the city are reporting increased numbers of patients presenting with flu-like symptoms — including fever, cough, sore throat, fatigue and body aches — particularly among children, the elderly and pregnant women. Medical professionals note that H3N2 often causes longer-lasting symptoms than typical seasonal flu, and severe cases can lead to complications such as pneumonia in high-risk individuals.
Physicians also highlight that influenza and COVID-19 share overlapping symptoms, making diagnosis challenging without proper testing. Health authorities recommend preventive measures such as flu vaccination, mask-wearing, avoiding crowded places and frequent hand washing to reduce transmission. Severe symptoms or persistent illness warrant full clinical evaluation, including blood work and chest imaging where appropriate.
