London, United Kingdom — The UK Health Security Agency (UKHSA) is currently probing a surge of shigella infections that may pose a serious public health threat. With multiple cases tied to recent travel, the investigation highlights rising concerns among health officials.
The outbreak has been traced back to Cape Verde, where six British citizens have died this year after visiting the islands. Notably, four of these fatalities occurred between August and November 2025, prompting a closer examination by health authorities.
Gauri Godbole, deputy director of gastrointestinal infections at the UKHSA, stated that investigations remain ongoing as they assess numerous shigella cases reported across the country. The majority of affected individuals had traveled to Cape Verde, particularly in regions known for tourism, such as Santa Maria and Boa Vista.
Shigella is known to trigger severe gastrointestinal symptoms, including both watery and bloody diarrhea, accompanied by stomach cramps and fever. The bacteria can spread through contaminated food or water, often linked to travel abroad. Additionally, it can also be transmitted during sexual activity.
Between October 1 and December 22, 2025, there were 137 confirmed shigella cases in the UK, with 109 of them involving individuals who had recently traveled to Cape Verde. This alarming trend has led the UKHSA to issue a public advisory urging enhanced hygiene measures to curtail the infection’s spread.
Health officials emphasize the need for rigorous handwashing practices, particularly after using restrooms, changing diapers, and before preparing meals. Such preventive measures are critical in reducing the likelihood of additional infections.
As the situation develops, the UKHSA is committed to monitoring the outbreak closely while providing the necessary guidance to the public. The agency continues to stress the importance of prompt medical attention for anyone experiencing symptoms consistent with shigella infection, especially if they have recently traveled to affected areas.
