Respiratory season (influenza, COVID-19, RSV)
As of 2026-10-06, this topic remains a global watch item rather than a single outbreak. The retrieved evidence points to continued seasonal movement in the main respiratory viruses—influenza, SARS-CoV-2, and RSV—with influenza and COVID-19 still the clearest officially described global signals. The most recent current-window item retrieved was a 2026-10-02 media report from Japan describing an unusually early influenza season that began in August and continued rising through September. In the latest WHO global influenza situation retrieved, WHO said global influenza activity had increased but remained within expected seasonal ranges, while noting some early northern hemisphere starts, some unusually long southern hemisphere seasons, and growing detection of an A(H3N2) J.2.4.1/K subclade without evidence of increased severity. In the latest WHO global COVID-19 situation retrieved, WHO said SARS-CoV-2 activity had risen across multiple regions in 2025, variant patterns were shifting toward NB.1.8.1, and global public health risk remained high, but surveillance and severe-outcome reporting were limited in several regions. No WHO DON on RSV was retrieved in this session. The main uncertainty is timeliness: current 7-day global official figures were sparse in the retrieved material. What to watch next is whether early influenza activity appears across more northern hemisphere countries, whether COVID variant turnover translates into sharper growth or severity, and whether RSV begins rising in parallel and adds hospital pressure.
Situation as of 6 Oct 2026
Official
The latest official global picture retrieved comes from WHO updates rather than a current-week dashboard. WHO’s seasonal influenza global situation said influenza activity had increased globally, with some early starts in the northern hemisphere and unusually long southern hemisphere seasons, but that overall activity remained within expected seasonal ranges; A(H3N2) J.2.4.1/K subclade viruses were rising without current evidence of greater severity. WHO’s latest retrieved COVID-19 global situation said SARS-CoV-2 activity had increased across parts of the Eastern Mediterranean, South-East Asia, and Western Pacific regions, that NB.1.8.1 was increasing, and that the global public health risk remained high, while also warning that surveillance and reporting of hospitalizations, ICU admissions, and deaths were limited in several regions. No WHO DON on RSV was retrieved in this session.
Media, unverified
Media retrieved in the last 7 days were sparse. The main item found was a 2026-10-02 report from Japan saying the country’s influenza season began in August 2026, the second earliest start since 1999, and that reported cases kept rising through September.
Control measures
The main measures in the retrieved sources are vaccination, virological surveillance, and routine respiratory-risk reduction. WHO emphasizes influenza and COVID-19 vaccination, continued surveillance through GISRS and related systems, and risk-based integrated COVID-19 management. The Japan report says the health ministry urged people to avoid crowded places when unwell, keep rooms ventilated, and wash hands after spending time in public places. No travel restrictions, border measures, or broad closure policies were described in the retrieved documents.
Timeline

- · WHO published a global seasonal influenza update saying activity had increased globally but remained within expected seasonal ranges, with some early northern hemisphere starts, some unusually long southern hemisphere seasons, and rapid growth of A(H3N2) J.2.4.1/K subclade viruses without evidence of increased severity.
- · A media report from Japan said the 2026 influenza season had started in August, the second earliest start since 1999, and that cases continued to rise through September.
