Health officials in Sweden have confirmed the first case of a new and more dangerous strain of mpox, Clade 1, outside of Africa. This strain is known for causing severe illness and higher mortality rates compared to the strain that caused a global outbreak in 2022. The patient in Sweden is currently receiving specialized care, and the country’s public health agency is closely monitoring the situation.
Clade 1 has been predominantly circulating in African nations, where it has led to numerous cases and deaths. However, with the virus now present in Sweden, experts are concerned that it may have already reached the UK. Despite reassurances from UK health authorities that the risk of widespread transmission remains low, the emergence of this strain has raised alarms about the potential for rapid spread, particularly within sexual networks.
The previous global mpox outbreak, driven by a milder strain, primarily affected men who have sex with men. It was contained largely due to a vigorous vaccination campaign. However, the effectiveness of the existing mpox vaccine against Clade 1 remains uncertain, adding to the urgency of the situation.
Global health experts, including those at the World Health Organisation, have declared this new strain a public health emergency of international concern. They stress the need for robust surveillance and contact tracing to detect and contain new cases early. As the situation develops, it is vital that healthcare workers remain vigilant and prepared to respond to potential outbreaks.
