Pakistan’s National Institutes of Health (NIH) has issued a warning about a sharp rise in seasonal influenza cases across the country. Health officials say the increase is mainly due to a fast-spreading strain of influenza A(H3N2), often called “super flu.” While the virus is spreading nationwide, experts stress that it is still treatable with standard care and that vaccination remains the best protection.
The warning comes at a time when flu cases are rising globally. The World Health Organization has also reported an increase in H3N2 cases in many countries, including the United Kingdom and parts of Europe. In Pakistan, the NIH recorded more than 340,000 suspected flu-like illness cases between epidemiological weeks 44 and 49. Of the samples tested, around 12 percent were confirmed as H3N2.
Since last month, about 1,691 flu cases have been reported across Pakistan, with a noticeable portion linked to this strain. Health experts say the rise is connected to a new genetic version of the virus known as sub-clade K. This strain has also become common in countries like the United States and the UK. Despite this change, doctors confirm that the treatment for H3N2 remains the same as for other types of flu.
Medical professionals explain that flu symptoms usually appear suddenly and are stronger than those of a common cold. Many patients experience a high fever, severe tiredness, body pain, and a dry cough. These symptoms can make daily activities difficult, especially for the elderly, children, and people with weak immune systems.
Although the current flu vaccine may not fully prevent infection from the new sub-clade, health officials say it still offers strong protection against serious illness. Vaccinated people are less likely to need hospital care or face life-threatening complications. Doctors strongly encourage people to get vaccinated, especially during peak flu season.
H3N2 spreads very easily. The virus passes from person to person through coughs, sneezes, close contact, and touching surfaces that carry the virus. A person can spread the flu even before symptoms begin and remain contagious for up to a week. Crowded places, poor ventilation, and close gatherings increase the risk.
Health authorities advise people to take simple precautions. Regular hand washing, covering the mouth when coughing, wearing masks if unwell, and staying home during illness can help reduce the spread. With awareness, timely care, and vaccination, experts believe the current flu wave can be controlled and serious outcomes can be avoided.
