UK Detects First Case of More Contagious Mpox Strain

The UK has reported its first confirmed case of mpox, previously known as monkeypox, associated with the recent outbreak in parts of Africa.

This case pertains to the more transmissible Clade 1b strain, which is raising concerns due to its enhanced ability to spread among individuals.

The affected individual, who had recently returned from a holiday in one of the impacted African nations, began experiencing flu-like symptoms on 22 October, followed by the onset of a rash two days later.

The mpox rash, characterized by pus-filled lesions, can persist for up to a month, while other common symptoms include fever, headaches, and fatigue.

Currently, the patient is receiving treatment at the Royal Free Hospital’s specialized high-consequence infectious diseases unit in London.

Laboratory tests have confirmed that the infection is linked to Clade 1b, which has been noted for its potential to spread more readily through close physical contact, including sexual interactions, compared to other mpox variants.

This year, Clade 1b cases have been reported in several African nations, including the Democratic Republic of Congo, Kenya, Burundi, and Rwanda.

In contrast, the related Clade 1a is primarily associated with transmission through infected animals or the consumption of bushmeat. Although Clade 1b appears to be milder than its counterpart, the precise infection rates remain challenging to determine.

Mpox was designated a global health emergency by the World Health Organization in the summer, underscoring the need for vigilance as health officials continue to monitor this evolving situation.
