Increase of Cyclospora cayetanensis cases in the UK linked to travel to Mexico

United Kingdom

The UK Health Security Agency (UKHSA) is reporting an increase in cases of the Cyclospora cayetanensis parasite in individuals returning from Mexico. To date, 74 people in England, Wales and Scotland have reported falling ill from the infection. During the period of 12 May to 14 August 2023, both men and women were affected, with women comprising 52 percent of the cases. The median age of those affected was 44 years. Of the individuals who provided travel details, the majority revealed they stayed in numerous hotels within the Riviera Maya and Cancún regions, and consumed various foods and drinks as part of all-inclusive holiday packages.

It is worth noting that cyclosporiasis outbreaks among UK travelers returning from Mexico have been a recurring issue since 2015, with the exceptions of 2020 and 2021 during the COVID-19 pandemic. However, the annual incidences of the infection have differed, with 79 cases in 2015, 359 in 2016, 82 in 2017, 61 in 2018, 67 in 2019, and 36 in 2022.

Cyclospora, a protozoan parasite, is spread through the consumption of contaminated food or drink. Symptoms can present as frequent, watery diarrhea, abdominal cramping, bloating, nausea, flatulence, low-grade fever, loss of appetite and weight. While infections are usually mild and self-limiting, complications can arise in immunocompromised individuals, and instances of severe or prolonged infections may necessitate treatment with antibiotics.

As a cautionary measure, visitors to Mexico are urged to practice good food and water hygiene, regardless of the quality of their accommodation. Ideally, they should only consume food that has been freshly prepared, thoroughly cooked, and served piping hot. Some items, like fresh uncooked berries and herbs, unpeeled fruit, and salad items, are best avoided due to the difficulty in sterilizing them effectively.

In case you are experiencing Cyclospora symptoms, it is important to report it. It can help to detect & resolve outbreaks early and prevent others from being harmed, and it enables better surveillance. If symptoms persist, seek medical care.
