Super flu presence in Philippines not alarming, says DOH

The Department of Health stated that the presence of a "super flu" variant in the Philippines is not alarming, but advised Filipinos traveling to North America and the United Kingdom to get the northern hemisphere vaccine amid rising cases in the US and Europe.

On Monday, Health Secretary Ted Herbosa stated during a Palace briefing that the public should not be alarmed by the presence of subclade K, a variant of the influenza A (H3N2) virus, in the Philippines. The Department of Health reported 41 cases from August 6 to October 24 of last year, with all patients having recovered.

"The warning I will give is for Filipinos that will travel to the temperate countries, that will go to North America, to the UK. If you’re going there, be knowledgeable that there is a spread of super flu in (those areas)," Herbosa said. He advised getting the northern hemisphere vaccine for those traveling to cold places, not the southern hemisphere shot.

Although flu is a self-limiting illness, the DOH recommended vaccinations especially for the elderly and those with medical conditions. "As we very well know, flu is a self-limiting illness, unless you have a medical condition, you’re elderly, so we still recommend the use of the flu vaccine," he added. Precautionary measures include staying home when sick and wearing face masks to prevent spread.

The super flu has been sweeping parts of the globe in recent months, leading to increasing cases in the US and Europe.

Central Java's Health Department detected one case of super flu, or influenza A H3N2 subclade K, in Semarang at the end of December 2025. Meanwhile, Hasan Sadikin Hospital in Bandung confirmed 10 cases in West Java from August to November 2025, with one patient dying due to comorbidities. Health officials stress that this is not a new virus and the situation is under control.

A mutation of the influenza A virus, known as the H3N2 K subclade, has led to increased hospitalizations in Europe and the United States, though no more severe cases are reported. In Latin America, including Mexico, preventive surveillance is in place without this variant predominating. Authorities recommend vaccination for vulnerable groups amid the risk of spread.

Building on recent surges in Europe and the US, the World Health Organization has issued a formal alert for the 2025-2026 flu season due to the rapid global spread of influenza A(H3N2) subclade K (J.2.4.1) since August 2025. While not more severe, its advance prompts preparations in the Northern Hemisphere and anticipation in the Southern Hemisphere, including Brazil.

Following initial detections in neighboring South American countries, the H3N2 influenza A K subclade has now reached Argentina, with confirmed cases in Buenos Aires, Santa Cruz, and Neuquén, including hospitalizations for pneumonia. Authorities are advancing the 2026 flu vaccination campaign for at-risk groups, while current vaccines offer partial protection against severe illness, bolstered by antivirals like oseltamivir.
