The Northern Ireland Public Health Agency (PHA) and Health Minister Mike Nesbitt have confirmed a concerning uptick in mpox cases, with 21 infections recorded over a recent three-week period. This alarming increase highlights a stark contrast to the nine total cases reported across the region from early 2023 to 2026.
This outbreak marks the first documented instances of the Ib strain of mpox in Northern Ireland, a significant shift from the clade II strain observed in previous years (2022-2025). The recent cases predominantly affect gay, bisexual, and other men who have sex with men (GBMSM), reflecting similar transmission patterns seen across Europe and the rest of the UK.
Despite the spike in cases, Health Minister Mike Nesbitt has sought to reassure the public, stating the situation is “not a matter of particular concern.” He noted that the increase aligns with broader trends in transmission and that mpox is no longer classified as a high-consequence infectious disease (HCID).
Symptoms of Mpox
The viral infection can present a range of symptoms lasting up to three weeks, including:
- A blistering skin rash, often starting on the face or genitals before spreading
- High temperature, fever, or chills
- Swollen glands and lymph nodes
- Headaches, fatigue, and joint or muscle aches
In light of the recent outbreak, the Public Health Agency is actively encouraging eligible individuals to get vaccinated, particularly ahead of summer travel and events. The vaccine offers protection against all circulating types of mpox.
Eligibility for the vaccine in Northern Ireland includes:
- GBMSM or trans/non-binary individuals with multiple sexual partners, who participate in group sex, or visit sex-on-premises venues
- Staff members working at sex-on-premises venues
- Individuals in close contact with confirmed mpox cases
- Healthcare workers in designated high-risk clinical settings
The PHA’s proactive stance aims to curb further spread of the virus and safeguard public health.
