A new variant of mpox has been identified in England after a recent traveler from Asia tested positive, health officials confirmed. Genome sequencing revealed the infection to be a recombinant strain, combining genetic material from clade 1, the more severe form of the virus, and clade 2, which was responsible for the 2022 global outbreak.
The UK Health Security Agency said it is assessing the significance of the variant, noting that viral evolution is expected while multiple strains circulate. Although most mpox cases remain mild, experts urged eligible individuals to get vaccinated as a precaution.
Mpox, formerly known as monkeypox, spreads through close physical contact with blisters or contaminated materials, and symptoms may take up to three weeks to develop. Patients typically experience fever, headache, muscle pain and exhaustion, with a rash appearing shortly after.
While scientists say the emergence of the recombinant strain is not surprising, it highlights the virus’s ability to evolve and the need for continuous surveillance. The World Health Organization recorded nearly 48,000 global mpox cases and over 200 deaths this year, with outbreaks still occurring in several regions.
Health authorities stress that further analysis is needed to determine whether the new strain poses any increased risk, though experts say monitoring its spread and behaviour will be crucial.
