London, August 19, 2024 – UK health officials are gearing up for potential cases of a newly emerged mpox virus strain, despite emphasizing that the risk to the general population remains low. The proactive measures come in the wake of a recent declaration by the World Health Organization (WHO) that ongoing outbreaks in West and Central Africa now constitute a global health emergency.
Mpox, formerly known as monkeypox, is a contagious virus that can lead to painful skin lesions and other severe symptoms. Although the current risk in the UK is deemed minimal, health authorities are taking no chances, particularly in light of the emergence of Clade 1b, a new and potentially more dangerous strain of the virus, first identified in the Democratic Republic of the Congo (DRC).
The WHO’s declaration underscores the urgency of the situation, as Clade 1b has been linked to severe illness and fatalities in the DRC, where at least 450 people have died. The virus has also been detected in a growing number of African countries over the past year, raising concerns about its potential to spread globally if not contained.
In response, the UK Health Security Agency (UKHSA) is implementing precautionary measures to ensure that the healthcare system is prepared for any eventualities. Dr. Meera Chand, the deputy director of the UKHSA, stated, “The risk to the UK population is currently considered low. However, planning is under way to prepare for any cases that we might see in the UK.”
These preparations include raising awareness among healthcare professionals about the key signs and symptoms of mpox, ensuring the availability of rapid testing, and developing protocols for the safe clinical management of cases. The UKHSA’s focus is on early detection and prevention to minimize the potential spread of the virus.
Mpox can be transmitted through close contact with an infected individual or contaminated materials such as bedding and surfaces. The virus typically presents with symptoms like skin rashes, pus-filled lesions, fever, headaches, and muscle aches. While most cases resolve within two to four weeks, the disease can be fatal, particularly in individuals with weakened immune systems, pregnant women, and children.
The UK has a history with mpox, having experienced a significant outbreak in May 2022. That outbreak predominantly affected men who have sex with men and was effectively managed through a targeted vaccination campaign, which significantly reduced transmission. By the end of 2022, the UK had reported 3,732 confirmed and highly probable cases. This year, 239 cases have been reported up to July, with the majority occurring in England. Testing and contact tracing are ongoing to monitor and control any further spread.
The global concern over mpox is not new. In 2022, the WHO declared an outbreak of Clade 2 mpox as a public health emergency of international concern after the virus spread to nearly 100 countries, including those in Europe and Asia, where it was not commonly found. This emergency was lifted in May 2023 following a decline in cases, but the recent surge in Clade 1b infections has reignited fears.
While the UK has not yet reported any cases of the Clade 1b strain, the global nature of the outbreak means that vigilance is essential. International travel and the interconnectedness of countries make it plausible for the virus to spread beyond Africa, particularly if global action is not taken.
Dr. Chand emphasized the importance of a coordinated international response to prevent the virus from gaining a foothold in regions where it is not endemic. “We are closely monitoring the situation and working with international partners to ensure that we can respond swiftly if the need arises,” she said.
As the world grapples with the ongoing challenges posed by infectious diseases, the situation with mpox serves as a reminder of the importance of preparedness, vigilance, and global cooperation in safeguarding public health. The UK’s proactive stance, despite the low risk, reflects the lessons learned from past outbreaks and the commitment to protecting its population from emerging threats.
