A recent study has identified sexually transmitted shigella as a significant public health threat in the UK, with alarming increases in cases. The research, conducted by the University of Cambridge and the UK Health Security Agency, shows that infections from sexual contact rose from 2,052 in 2023 to 2,560 in 2025. This trend highlights a shift in how shigella is transmitted, particularly affecting gay and bisexual men, who are the most impacted demographic.
The study reveals that sexually transmitted strains of shigella spread much further than non-sexually transmitted variants, averaging 117 kilometres compared to just 46 kilometres. This suggests that sexual networks are facilitating a more rapid and widespread transmission of the infection, raising concerns about the effectiveness of current public health strategies.
Compounding the issue is the growing antibiotic resistance among these strains, with 70% showing resistance to at least one clinically relevant antibiotic. This is a stark contrast to the 40% resistance found in non-sexually transmitted cases. Such resistance complicates treatment options and poses a significant challenge for healthcare providers.
Experts are urging increased awareness and proactive measures within affected communities. Individuals experiencing symptoms such as severe diarrhoea or abdominal pain are advised to seek medical attention and discuss their sexual health history. The call for community engagement is crucial to mitigate the spread of this emerging public health challenge.
