Jakarta \u2014 Early 2026 is under the spotlight as an influenza variant called \u201cSuper Flu\u201d<\/em> or Influenza A (H3N2) subclade K has reportedly entered and been detected in Indonesia. This detection is based on genomic examinations conducted by the Indonesian Ministry of Health at the end of December 2025.<\/p>\n\n

1. Subclade K: Variant Under Monitoring<\/h2>\n\n

Subclade K is the result of the evolution of the influenza A H3N2 virus that has long circulated globally. Simply put, this is not a \u201ccompletely different new virus,\u201d but a variant with specific mutations that make it very dominant in many countries during the 2025\u20132026 flu season.<\/p>\n\n

International media such as Stat News<\/em> and news from the US reported that the 2025\u20132026 flu season was dominated by the Subclade K variant in several countries, with higher transmission activity than the previous season.<\/p>\n\n

2. Evidence of Subclade K’s Entry into Indonesia<\/h2>\n\n

According to the Indonesian Ministry of Health, the variant has been detected in Indonesia since December 25, 2025, through a surveillance program conducted on patients with influenza symptoms. These findings indicate the presence of the Subclade K variant in several provinces, including East Java, South Kalimantan, and West Java.<\/p>\n\n

The number of confirmed cases by the end of December 2025 reached dozens, with over 800 influenza-positive specimens examined.<\/p>\n\n

3. National Media Reports: What Does the Ministry of Health Say?<\/h2>\n\n

Several national media outlets such as detikHealth<\/em> and CNN Indonesia<\/em> reported that although this variant has been detected, there has not been a large surge in national influenza cases directly linked to Subclade K. However, its presence indicates that this variant has begun to circulate locally in Indonesia. <\/a><\/p>\n\n

4. Global Trends: Dominance This Flu Season<\/h2>\n\n

Reports from abroad indicate that Subclade K has become the dominant variant in the 2025\u20132026 flu season. For example:<\/p>\n\n
