Mpox in Sierra Leone: What’s Gambia Doing About a Spillover?

 As of 17 June 2025, there have been over 4,000 confirmed cases of mpox and 25 related deaths in Sierra Leone, raising concerns that the virus could spread to neighbouring countries and spark a larger outbreak across the densely populated West African region. In Sierra Leone, the virus appears to be spreading from person to person, primarily among young men and women.

In The Gambia, we should be worried about a possible spillover. The cultures of West African countries are closely linked, reflecting a shared ancestry. Additionally, there is a significant flow of trade and trafficking of people and goods across the sub-region, increasing the risk of mpox cases crossing borders undetected.

We therefore draw the attention of the Ministry of Health particularly the Disease Control Unit to remain on high alert. Raising awareness through announcements on local radio stations will go a long way in informing the general public and ensuring early prevention.

There is a clear need for proactive measures to be put in place to prevent the spread of the virus in The Gambia. Effective risk communication, including the sharing of critical health information, is essential to empower individuals to make informed and responsible decisions about their safety and personal health.

Mpox (formerly known as monkeypox) is caused by the mpox virus, a member of the Orthopoxvirus genus, which also includes smallpox and chickenpox. Initially, close physical contact with infected persons was the primary known mode of transmission. However, with the emergence of various mpox virus subclades (Clade 1a and 1b, Clade 2a and 2b), sexual transmission has been documented in several studies.

As the region watches developments in Sierra Leone with concern, The Gambia must act decisively and early. The threat is real, and complacency is not an option.
