Britons returning from specific countries have been urged by the UK Health Security Agency (UKHSA) to seek immediate medical assistance if they experience three particular symptoms. These symptoms could indicate an infection known as mpox, which has recently been classified as a public health emergency of international concern by the World Health Organisation (WHO). Formerly called monkeypox, mpox can lead to fever, swollen glands, joint pain, and anal bleeding, among other signs.
A variant of the infection called clade I was initially identified in the Democratic Republic of the Congo (DRC) last year and has since spread to various countries in Africa as well as beyond the continent. The UKHSA highlighted that mpox is a viral infection that spreads through close person-to-person contact and has different clades. Clade II mpox has been present in the UK since 2022, while clade I mpox had been limited to five countries in Central Africa before recent transmissions in several countries in East and Central Africa.
Travellers returning from affected countries are advised to contact NHS 111 if they notice new spots, blisters, or ulcers within 21 days of their return. Nations in Central and East Africa where clade I cases have been reported include DRC, Republic of the Congo, Central African Republic, Burundi, Rwanda, Uganda, Kenya, Cameroon, and Gabon. Bordering countries with potential clade I exposure are Angola, South Sudan, Tanzania, and Zambia.
Confirmed cases of clade I mpox have been recorded in Burundi, Kenya, Rwanda, and Uganda, with links to the DRC. Additionally, Sweden and Thailand have reported confirmed cases in travellers connected to countries involved in the clade I outbreak. Symptoms of mpox encompass a skin rash, fever, headaches, joint pains, swollen glands, shivering, and exhaustion, usually followed by rash development on the face spreading to other body parts.
The transmission of mpox occurs through direct contact with affected individuals, contact with contaminated materials, or infected animals. It is advised to call NHS 111 if a rash with blisters or sores appears post-travel to Central or East Africa or with any symptoms of mpox in close contact with affected individuals. The UKHSA stresses the importance of staying at home and avoiding close contact with others, as well as sharing personal items until receiving further guidance.
The announcement serves as a crucial warning to travellers returning from specific regions and underscores the importance of prompt medical attention and precautions to prevent the further spread of this concerning infection.
