UK Health Security Agency urges the public to be vigilant amid a surge in mpox cases

In a stark warning that highlights the growing threat of mpox in the UK, the UK Health Security Agency (UKHSA) has issued a public plea urging residents to seek testing, report symptoms and take preventive measures. The announcement, covered in detail by the Manchester Evening News, follows a marked uptick in confirmed mpox cases across the country and comes as the national vaccine rollout reaches its peak.

The backdrop: What is mpox and why does it matter?

Mpox, formerly known as monkeypox, is a viral infection that can spread through close contact with infected animals or people. Its most common symptoms include a distinctive rash, fever, headache, swollen lymph nodes and flu‑like illness. Although the disease is generally mild, it can lead to serious complications, particularly in people with weakened immune systems. In the United Kingdom, the virus was first detected in 2022 and has since evolved into a sporadic outbreak that the UKHSA now says is on the rise.

The agency’s latest data show that 1,500 confirmed cases have been recorded across the UK, representing a 70 % increase over the previous month. While the overall risk to the general public remains low, the Agency notes that certain populations—particularly men who have sex with men, individuals with multiple sexual partners, and those living with HIV—face a higher likelihood of infection.

The public plea: What you need to know

According to UKHSA spokesperson Dr Emma S. Jones, “We’re concerned about the increasing number of cases and urge anyone who develops symptoms or has had recent close contact with someone who has tested positive to seek medical care immediately.” The public is advised to seek a clinical test if they notice:

• A rash that is blister‑filled and progresses to scabs
• Fever or flu‑like symptoms lasting more than 48 hours
• Swollen lymph nodes, particularly in the groin or under the arms
• Pain in the joints or muscles

If any of these signs appear, the UKHSA recommends contacting the NHS 111 service or visiting a GP for a swab test. Early detection is crucial not only for treatment but also for preventing further spread.

Vaccination: Availability and eligibility

In addition to testing, the UKHSA highlighted the importance of the post‑exposure vaccine (Jynneos) that has been made available through the national immunisation programme. Dr Jones noted that a single dose of the vaccine can significantly reduce the risk of developing symptomatic disease in those who have been exposed. “We encourage people who have been in close contact with a confirmed case—within 4 days of exposure—to get vaccinated as soon as possible,” she said. The vaccine is currently being distributed to high‑risk groups, and the Agency is working closely with local health authorities to expand access.

The UKHSA also stresses that vaccination is not a substitute for testing. “Vaccinated individuals can still develop mild symptoms and may unknowingly transmit the virus to others,” Jones warned.

Guidance for health professionals and contact tracing

For frontline workers, UKHSA has released detailed guidelines on personal protective equipment (PPE) and infection control. The Agency advises healthcare providers to use gloves and face masks when examining suspected cases and to follow strict hand‑washing protocols. A comprehensive set of guidelines is available on the UKHSA website, including a flow‑chart for isolation and testing procedures.

Contact tracing remains a cornerstone of the UKHSA’s strategy. The agency’s “Contact Tracing Toolkit”—which can be found on the UKHSA site—provides resources for tracing close contacts and advising them on testing and isolation. The Toolkit underscores that isolation periods may extend up to 21 days for those who have had unprotected contact with a confirmed case.

Global perspective and ongoing monitoring

The UKHSA’s warning is echoed by the World Health Organization, which has urged member states to maintain vigilance and accelerate vaccination campaigns. According to WHO’s latest briefing, the global case count has surged in several regions, and the virus is now classified as a “public health emergency of international concern.” The WHO’s guidance aligns with the UKHSA’s call for immediate testing and vaccination for high‑risk populations.

In addition to its domestic focus, the UKHSA monitors international travel patterns and is prepared to coordinate with the UK Border Agency to screen for symptoms and test travelers from high‑risk areas. The agency’s “Travel and Health” page, which offers up‑to‑date travel advisories, is frequently updated in light of new outbreak data.

How the public can help

The Manchester Evening News report emphasises that community cooperation is essential. Residents are urged to:

1. Recognise symptoms and act swiftly.
2. Seek testing through NHS 111 or a GP.
3. Report contacts to local health authorities.
4. Maintain hygiene—hand washing, mask use in crowded settings.
5. Get vaccinated if exposed or belonging to a high‑risk group.
6. Follow isolation guidelines until the 21‑day period is complete.

The UKHSA’s press release (https://www.gov.uk/government/news/ukhsa-issues-plea-to-public-about-mpox) details the full statement from the agency and provides links to the mpox guidance for healthcare professionals. Further information, including symptom charts, testing locations, and vaccine appointment booking, can be accessed on the UKHSA’s dedicated mpox webpage (https://www.gov.uk/guidance/mpox-information).

Looking ahead

While the numbers are still modest compared to the height of the 2022 outbreak, the UKHSA’s announcement signals a shift toward a more proactive stance. The Agency is intensifying its surveillance and is poised to expand the vaccine rollout as supply allows. By combining public awareness with robust testing and vaccination infrastructure, the UKHSA aims to curb the spread of mpox and prevent a potential second wave.

The Manchester Evening News remains committed to keeping residents informed. In the meantime, the agency’s message is clear: vigilance, prompt testing, and vaccination are the best tools against the growing threat of mpox. If you suspect you may have been exposed, act quickly—your health, and that of your community, depends on it.
