Cape Verde holidaymakers issued with government advisory over gastric illnesses

Increased cases of gastric illnesses linked to travel to Cape Verde have been identified by the UK Health Security Agency (UKHSA).

 

An investigation led by UKHSA, together with other public health agencies, found that of 158 confirmed Shigella cases reported since October 1, 2025 that are within this outbreak, 118 reported international travel. 

 

Of these, 112 (95%) travelled to Cape Verde, the majority to the Santa Maria and Boa Vista areas. Travel information for the remaining cases is not known. 

 

UKHSA has also identified increases in cases of Salmonella associated with travel to Cape Verde. 

 

A total of 43 cases of Salmonella from three separate clusters identified using whole genome sequencing since October 1 have been linked to travel to Cape Verde. 

 

The advisory, ahead of February half-term school holidays, followed a group legal action involving 300 British holidaymakers who fell ill on holidays to the Atlantic island state in 2022.

 

More than 1,500 British holidaymakers who have suffered gastric illness linked to holidays in Cape Verde since 2022, including the families of six Britons who have died, are being represented by Irwin Mitchell.   

 

A new UKHSA study looking at travel-associated gastrointestinal infections highlights the importance of taking simple precautions when travelling abroad. 

 

The research found factors that can increase the risk of infections like Salmonella, Shigella, Giardia and Cryptosporidium. 

 

These include using local swimming pools, local water and sanitation conditions and possible infection from some foods linked to catered hotels from buffets and excursion or day trip foods.  

 

Travellers can reduce their risk of gastrointestinal infections by taking care with food, water and basic hygiene.

 

Dr Gauri Godbole, UKHSA deputy director for gastrointestinal infections, food safety and one health, said: “February is a popular time for winter sun holidays and we want to help families make the most of their breaks by staying healthy. 

 

“Taking a few simple precautions against traveller’s diarrhoea and food poisoning can make all the difference. 

 

“The best way to avoid gastrointestinal infections, including Shigella and Salmonella, or passing them to others, is simply by washing your hands regularly and thoroughly with soap and water or alcohol gel – particularly after using the toilet, changing nappies, and before eating or preparing food. 

 

“Most episodes of traveller’s diarrhoea are short-lived, lasting for a few days. 

 

“During an episode of diarrhoea and vomiting, it is important to prevent dehydration particularly for young children, pregnant women, elderly people, and those with pre-existing illnesses as they can develop complications. 

 

“Continue to hydrate yourself with plenty of fluids and consider purchasing sachets of oral rehydration salt before travelling. If symptoms worsen or you have underlying medical conditions, please seek advice from your GP or pharmacy.”
