Is COVID Still a Pandemic in 2026? What "Baseline Circulation" Means

Six years on from COVID-19's emergence, the virus is still circulating in the UK, but the way health authorities describe and respond to it has changed enormously. As of UKHSA's monitoring in 2026, COVID-19 activity in the UK has been described as reaching a "baseline level" of circulation, a very different framing to the acute pandemic emergency declared by the World Health Organization back in March 2020.

Pandemic, endemic and baseline: what the terms mean

A pandemic refers to a new disease spreading widely across multiple countries or continents, typically because a population has little or no existing immunity to it. As immunity builds up over time through infection and vaccination and as a virus settles into a more predictable, recurring pattern, it's generally described as becoming endemic. "Baseline circulation" is a related, more specific term used in surveillance reporting to describe a steady, expected level of ongoing activity, as opposed to a sharp spike or unusual surge above what's typically expected for the time of year.

What UKHSA monitoring shows

UKHSA continues to publish regular national flu and COVID-19 surveillance reports, tracking indicators including test positivity rates, hospital admissions and the prevalence of circulating variants such as XFG and NB.1.8.1. This ongoing monitoring is how "baseline" activity is identified and distinguished from a genuine seasonal surge, allowing health authorities to respond proportionately rather than treating every case as part of an emergency.

How this compares to earlier years of the pandemic

In the pandemic's first two years, case numbers, hospital admissions and deaths were tracked and reported daily, alongside legally enforced restrictions including lockdowns and mandatory self-isolation. Today, COVID-19 is managed similarly to other established respiratory illnesses such as flu, with no legal restrictions in place across the UK, routine seasonal vaccination programmes for higher-risk groups and surveillance continuing quietly in the background rather than dominating daily headlines.

What this means for you day to day

For most people, this shift means COVID-19 no longer meaningfully changes how they go about daily life. There's no legal requirement to test, isolate or wear a mask and guidance broadly mirrors general advice for any contagious respiratory illness: stay home if you're unwell, be considerate of vulnerable people around you and keep up with vaccinations if you're in an eligible group. For people at higher risk of severe illness, including older adults and those with certain health conditions, staying informed about current guidance and vaccine eligibility remains more directly relevant.

Does baseline mean the risk is gone?

No. Baseline circulation means COVID-19 is behaving in a stable, expected way rather than surging unpredictably, not that the virus poses no risk at all. Severe illness and death from COVID-19 still occur, concentrated largely among older adults and people with significant underlying health conditions, which is exactly why targeted vaccination programmes for these groups have continued well beyond the acute phase of the pandemic.

Frequently asked questions

Has the WHO officially ended the COVID-19 pandemic?

The WHO ended the COVID-19 Public Health Emergency of International Concern designation in May 2023, while noting the virus remained a significant ongoing health issue requiring continued monitoring, a status that has broadly continued since.

Could COVID-19 activity spike again?

Respiratory virus activity, including COVID-19, typically follows seasonal patterns, with activity generally rising over autumn and winter. Surveillance systems are specifically designed to flag any unusual surge above the expected baseline quickly.

Where can I check current UK COVID-19 activity?

UKHSA's national flu and COVID-19 surveillance reports, published regularly on GOV.UK, provide the most current, detailed picture of activity levels across England.

How other countries are approaching it

The shift towards managing COVID-19 as an endemic, seasonally circulating illness hasn't been unique to the UK. Most countries with established healthcare systems have moved towards broadly similar approaches, including the United States, Australia and countries across the European Union, generally lifting formal pandemic-era restrictions between 2022 and 2023 and shifting towards routine seasonal vaccination programmes for higher-risk groups. Exact policies and eligibility criteria vary between countries, reflecting differences in healthcare systems and national risk assessments.

What could change this picture

Health authorities continue to monitor for developments that could shift the current baseline picture, including the emergence of a variant with meaningfully increased severity, reduced vaccine effectiveness, or a significant unexpected surge in cases. Surveillance systems like UKHSA's are specifically designed to detect these kinds of changes early, which is part of why routine monitoring continues even during periods of stable, baseline activity.

Frequently asked questions

Could COVID-19 restrictions ever return?

In principle, yes, if a significant new threat emerged that warranted it, similar to how measures were introduced in 2020. Current evidence and surveillance data don't suggest this is likely in the near term.

How does the UK's current approach compare to how flu is managed?

The current approach for COVID-19, including seasonal vaccination for higher-risk groups and routine surveillance without legal restrictions, closely mirrors how seasonal flu has long been managed in the UK.

What "endemic" actually means in practice

Describing a disease as endemic doesn't mean it has disappeared or become harmless. It means the level of disease in a population has settled into a relatively predictable, sustained pattern rather than the unpredictable, rapidly escalating spread characteristic of a pandemic's acute phase. Seasonal flu, for example, is endemic in the UK, circulating every winter at broadly predictable levels while still causing a meaningful number of hospitalisations and deaths each year, particularly among older and more vulnerable people.

Why the WHO's declaration mattered

The WHO's May 2023 decision to end the Public Health Emergency of International Concern designation for COVID-19 was a significant, formal milestone, reflecting a global assessment that health systems could manage the ongoing burden of the disease without the exceptional emergency measures used earlier in the pandemic. It didn't mean COVID-19 had stopped being a public health concern entirely and the WHO continues to monitor the disease as it does other established respiratory illnesses.

What this means for how we cover COVID-19

Reflecting this shift, our own coverage on this site has moved away from pandemic-era case tracking towards more practical, ongoing guidance, covering topics like current variants, seasonal vaccination eligibility and symptom management. This mirrors how health information more broadly has adapted, treating COVID-19 as an established part of the seasonal illness landscape that still deserves attention and clear information, without needing the emergency framing of 2020 and 2021.

A quick recap

COVID-19 is no longer classified as a global health emergency and the UK, along with most other countries, now manages it as a seasonally circulating, endemic illness rather than through pandemic-era restrictions. This doesn't mean it's no longer worth taking seriously, particularly for people in higher-risk groups, but it does mean the day to day approach looks much closer to how flu has long been managed.

How historians may eventually frame this period

Public health experts have drawn comparisons between COVID-19's transition to endemic status and how past pandemics, including the 1918 influenza pandemic, eventually settled into a recurring seasonal pattern after their initial acute phase. It's a useful reminder that this kind of transition, while it can feel gradual and undramatic while living through it, follows a pattern with real historical precedent.
