Multiple reports say a sexually transmitted bacterial gut infection, shigella, is spreading rapidly in the UK, prompting public health warnings. Sky News and other outlets cite findings from a study associated with the University of Cambridge, which links recent transmission to certain sexual networks, with coverage focusing particularly on some communities of gay men. Experts described shigella as a “distinct public health threat,” citing concerns about increased spread and the potential seriousness of disease. Reports indicate the illness can cause severe gastrointestinal symptoms, including diarrhoea, and may be associated with other symptoms such as fever and abdominal pain, though specific symptom lists vary by outlet. The coverage also emphasizes the need for awareness and timely medical attention, as delayed treatment can increase the risk of complications and further transmission. Overall, the sources agree that the situation is evolving and that shigella’s sexually transmitted route is contributing to its rise in particular groups, leading to calls for targeted prevention and hygiene measures alongside standard infection control guidance.
