London, United Kingdom — A rise in shigella infections across the UK has triggered an inquiry by the UK Health Security Agency (UKHSA), specifically noting that many of the confirmed cases are tied to recent travel. This uptick has heightened concerns regarding a potential public health crisis.
The outbreak is linked to Cape Verde, an archipelago off the northwest coast of Africa, where six British citizens have died since the beginning of 2023 after visiting the islands. Four of these fatalities were reported between August and November 2025, prompting authorities to intensify their investigatory efforts.
Gauri Godbole, who serves as the deputy director for gastrointestinal infections at UKHSA, shared insights on the situation. She indicated that a significant number of shigella cases in the UK are associated with travelers returning from Cape Verde, particularly those who stayed at hotels in the Santa Maria and Boa Vista areas.
Shigella is known for causing symptoms such as watery or bloody diarrhea, abdominal cramps, and fever. The infection can spread through contaminated food or water, often as a result of international travel. However, transmission can also occur during sexual activity.
Data from recent weeks highlights the urgency of the situation. Between October 1 and December 22, 2025, the UK reported 137 confirmed cases of shigella, with 109 of those involving individuals who had recently traveled to Cape Verde.
In light of these developments, the UKHSA is urging people to adopt enhanced hygiene practices to curb further transmission. Proper handwashing is particularly emphasized, especially after using the restroom, changing diapers, or handling food to mitigate the risks associated with the infection.
Public health officials are actively monitoring the outbreak and are in communication with healthcare providers to ensure timely reporting of new cases. As the investigation unfolds, additional findings may lead to further recommendations for the traveling public to ensure safety while abroad.
The UKHSA emphasizes the importance of vigilance and adherence to hygiene protocols, especially as travel resumes post-pandemic. With the winter season approaching, the agency encourages travelers to remain informed and take precautions to protect themselves and others against infectious diseases.
