London, United Kingdom — A surge in shigella infections has prompted an investigation by the UK Health Security Agency (UKHSA), raising alarms about potential public health implications. Many of the cases are tied to travel, particularly to the popular tourist destination of Cape Verde.
Since January 2023, six British nationals have succumbed to complications related to shigella after visiting the islands, with four deaths reported between August and November 2025. These worrying trends suggest that the outbreak may present a broader risk to public health in the UK.
Gauri Godbole, deputy director of gastrointestinal infections at the UKHSA, confirmed that the agency is closely monitoring the situation. “We are currently examining multiple shigella cases across the UK, with a significant number traced back to recent trips to Cape Verde,” she stated. Affected individuals are reported to have mostly stayed in hotels located in regions like Santa Maria and Boa Vista.
Shigella infections can lead to severe gastrointestinal symptoms, including watery and bloody diarrhea, stomach cramps, and fever. While the illness is often transmitted through contaminated food or water, it can also spread during or after sexual contact, highlighting the need for vigilance in both travel and personal hygiene.
Data from the UKHSA revealed that between October 1 and December 22, 2025, there were 137 confirmed shigella cases in the country. Notably, 109 of these cases involved individuals who had traveled to Cape Verde recently. This substantial proportion underscores the association between travel and infection.
As the investigation continues, the UKHSA is urging the public to adopt enhanced hygiene practices to mitigate further outbreaks. The agency emphasizes the critical nature of thorough handwashing, especially after using the restroom, changing diapers, or prior to food preparation.
In light of these findings, health experts recommend that travelers to high-risk areas remain alert to the symptoms of shigella and take preventive measures to protect themselves and others. This outbreak serves as a reminder of the potential risks associated with international travel, especially in regions where waterborne diseases are prevalent.
Authorities continue to collaborate with local health officials to monitor the situation and provide guidance to the public. As the investigation unfolds, the UKHSA remains committed to transparency and public health safety.
