ISLAMABAD: The National Institute of Health (NIH) has raised a high alert following the detection of H3N2 ‘super flu’ cases in Pakistan.
Reports from the NIH indicate that the H3N2 sub-clade “K” is rapidly spreading across the country. Current data reveals that 20% of circulating H3N2 samples in Pakistan belong to this more concerning sub-clade.
In light of this situation, the NIH has instructed federal and provincial health authorities to maintain heightened vigilance as super flu cases continue to rise.
The NIH has directed hospitals to prepare for increased outpatient visits and potential surges in hospital admissions. Since May 2025, 66% of reported Influenza A cases have been attributed to H3N2.
Surveillance reports show that over 340,000 suspected flu cases have been recorded in the past six weeks alone.
Health experts have warned that flu cases are expected to rise further during the winter months.
The H3N2 virus presents higher health risks for older adults, children, and pregnant women. Additionally, individuals with underlying conditions such as diabetes, cardiovascular disease, or respiratory disorders fall within the high-risk category. The NIH highlighted that crowded spaces and poorly ventilated indoor areas are significantly contributing to the virus’s rapid transmission.
The NIH has emphasized the need for stricter infection control measures across the country. It also reinforced the importance of seasonal influenza vaccination as a key method to reduce severe illness and mortality. The currently available vaccine has been confirmed effective against the H3N2 sub-clade “K.”
Early antiviral treatment was recommended for patients in high-risk groups, with warnings that delays could lead to complications such as pneumonia or respiratory failure.
The public has been urged to adopt preventive measures and prioritize timely vaccinations.
