New Mpox Variant Clade Ib Emerges in Europe
A new variant of the Mpox virus, known as clade Ib, is spreading rapidly in Africa and has now been reported in Europe, marking the first local transmissions outside the continent. The UK Health Authority (UKSHA) confirmed that two individuals in London have contracted the virus after coming into contact with a traveler who recently returned from several African countries. Both patients are currently hospitalized, and health officials are closely monitoring the situation to prevent further spread.
The World Health Organization (WHO) has classified these cases as the first local transmissions of Mpox clade Ib outside Africa since the organization raised its alert level in August 2024 due to rising cases on the continent. Hans Kluge, WHO Regional Director for Europe, emphasized that while the overall risk to the population in the UK remains low, the emergence of local transmission necessitates enhanced surveillance and contact tracing efforts by health authorities.
Symptoms and Transmission of Mpox
According to health officials, the symptoms of Mpox include a distinctive rash with spots and pustules, fever, headaches, muscle pain, back pain, fatigue, and swollen lymph nodes. Symptoms typically appear four to 21 days after exposure and can last for two to four weeks. Notably, Mpox can be transmitted through contaminated items such as towels and bed linen, as well as through close contact with infected individuals.
The UKSHA has reported that the current cases are linked to a traveler who tested positive for Mpox after visiting the Democratic Republic of Congo, Nigeria, and other countries experiencing outbreaks. The WHO has indicated that over 1,000 deaths have occurred in Africa due to Mpox, with significant vaccination efforts underway in countries like the Democratic Republic of Congo and Rwanda. The health authorities in Europe continue to monitor the situation closely, emphasizing the importance of preparedness in light of the new variant.
