The UK Health Security Agency (UKHSA) reports a sharp increase in cyclospora (cyclosporiasis) infections among people returning to the UK after travel, with many cases linked to Mexico. BBC Health and other outlets cite UKHSA figures showing 67 cases reported in returning travellers between 30 April and 15 July this year, with 48 of those involving travel to Mexico. The infection is caused by a parasite that leads to diarrhoea that can be frequent and sometimes described as “explosive,” alongside symptoms such as abdominal cramping, bloating, nausea, flatulence, low-grade fever, and loss of appetite and weight loss.
UKHSA says cyclospora does not naturally occur in the UK and that there is no risk of person-to-person spread. Health authorities expect more travel-associated cases during the summer holiday period, citing increased travel to Mexico and possible linked increases from travel to other areas, including the United States.
Travel health advice focuses on reducing exposure through strict food and water hygiene, including drinking bottled water, eating thoroughly cooked food, and avoiding higher-risk items such as fresh uncooked herbs, salad, and unpeeled fruit and berries. People who develop symptoms after travel are advised to seek medical care and mention their travel history.
