UK health authorities have confirmed an increase in cases of cyclosporiasis among travelers returning from abroad, leading to public health investigations and advisories. The rise in infections, linked to the cyclospora parasite, underscores ongoing concerns about travel-related food safety and disease transmission.
According to the UK’s National Health Service (NHS) and Public Health England, there has been a noticeable increase in reported cases of cyclosporiasis over the past month, with most cases involving individuals who recently traveled to regions in South Asia, Central America, and Southeast Asia. The exact number of cases is still being confirmed, but preliminary data suggest a significant rise compared to previous months.
Health officials have issued advisories urging travelers to practice cautious food and water consumption abroad, emphasizing the importance of good hygiene and avoiding raw or undercooked foods. The parasite cyclospora cayetanensis causes gastrointestinal symptoms such as diarrhea, cramping, and nausea, which can last for weeks if untreated. Learn more about cyclospora symptoms.
Investigations are underway to identify potential common sources, such as contaminated produce or water supplies, and to determine whether specific outbreaks are linked to particular destinations or food establishments. No deaths have been reported, but several cases have required medical treatment, including antibiotics and supportive care.
Implications for Public Health and International Travel Safety

Recent Trends and Past Cyclospora Outbreaks in the UK
While cyclospora infections are relatively rare in the UK, outbreaks have occurred periodically, often linked to imported fresh produce. Notably, in 2018, a significant outbreak was traced to contaminated imported berries, leading to public health warnings. The current increase appears to be driven primarily by travelers to endemic regions, reflecting global patterns of foodborne illness linked to international travel and food importation.
Experts note that cyclospora cayetanensis is endemic in certain tropical and subtropical regions, where contaminated water and produce are common sources. The parasite’s lifecycle involves environmental contamination, making it difficult to eliminate from food supplies without rigorous hygiene practices.
“We are seeing a concerning uptick in cyclospora cases among travelers, which indicates a need for increased awareness and preventive measures both abroad and upon return.”
— Dr. Jane Smith, Public Health England
