New Mpox Strain Merges Deadly Clades in UK
8 Dec
Summary
- A new mpox strain combining elements of two clades has been detected in England.
- The infected patient recently traveled to the UK from Asia.
- Health officials urge eligible individuals in the UK to get vaccinated against mpox.

Health officials in England have confirmed the detection of a new, mutated strain of mpox. This novel strain was identified in a patient who had recently traveled to the UK from Asia. Laboratory testing revealed that the virus contains genetic material from both the more severe clade 1b and the previously widespread clade IIb.
Experts expressed that this recombination is what they had feared, given the continued global spread of mpox. While the exact transmissibility and severity of this new strain are still under investigation, the UK Health Security Agency (UKHSA) stated it was not entirely unexpected as both clades are circulating. They are urging eligible individuals to get vaccinated to mitigate potential outbreaks.
The UKHSA has shared findings with the World Health Organization. They note that while mpox is often mild, it can become severe. Vaccination is highlighted as an effective protective measure, and anyone suspecting infection should contact NHS 111. Clade 1b has been particularly devastating in central Africa, causing significant mortality and miscarriages, though experts believe such high fatality rates are unlikely in developed nations due to better healthcare.
