Full reporting
The complete story
Influenza indicators in England are rising earlier than in recent years, but the overall level remains at baseline, the UK Health Security Agency said in its October 8 update. Its week 40 surveillance, covering September 28 to October 4, recorded flu test positivity of 6.5%, up from 5% the previous week. The overall weekly flu hospital admission rate was 1.97 per 100,000 people. UKHSA cautions that this admission surveillance began in week 40, so the rate cannot be compared directly with the preceding week.
The agency said September flu activity was higher than at the same point in each of the previous four winter seasons. It called this a possible sign of an early season, while stressing that current flu circulation is still very low. That distinction matters: rising indicators are a reason to pay attention, not evidence of a severe nationwide outbreak. The figures are for England, not all four UK nations.
UKHSA is urging people eligible for a flu vaccination to take it up. NHS England says the 2026 programme opened to further eligible groups from October 1, including adults aged 65 and over and some people with long-term conditions. Eligibility and booking routes depend on individual circumstances; NHS guidance provides the current details.

Our take
Analysis
What the evidence and search signal suggest
The measures point in the same general direction, but they answer different questions. Test positivity reflects the share of tested samples positive for flu; the hospital admission rate reflects illness severe enough to require admission. With hospital surveillance beginning in week 40, the current admission figure is a starting point, not proof of week-to-week acceleration.
Analysis and commentary are SearchTrends Daily’s interpretation. They are intentionally separated from the sourced account above.
Meaning
Why this matters
The first winter surveillance figures give households and health services an early signal to watch. UKHSA’s 6.5% positivity figure is up, but its baseline classification prevents the data from being mistaken for a high-flu alert. The vaccination message is immediate for those already eligible.
Background
How we got here
UKHSA tracks influenza through laboratory, GP and hospital indicators and publishes weekly winter respiratory reports. Its October 8 report is the first full weekly winter report of this season. The agency said trends had been rising since August; its comparison with recent Septembers is a warning sign rather than a forecast of how many cases the season will ultimately bring.
Outlook
What is likely to happen next
UKHSA’s next weekly report will show whether positivity, GP consultations and hospital admissions continue to rise. Those later data will better establish the season’s direction. Eligible readers can use NHS information now to check vaccination options.

Commentary
What we think
Our view: the story is most useful when it holds both parts of UKHSA’s message together. Flu activity is rising and worth monitoring; it is still low. A dramatic early-season label would overstate what the present evidence shows.
