Rather, it highlights why food and water hygiene matters, particularly when travelling in areas where Cyclospora is more common. When travelling, particularly in regions where food and water-borne infections are more common, freshly cooked food and safe drinking water remain sensible precautions. If diarrhoea continues, particularly after returning from Mexico or another area where Cyclospora occurs, tell your GP about your travel history and ask whether specific testing for Cyclospora is appropriate. If you come home from holiday and develop persistent, watery diarrhoea, particularly if it lasts longer than expected or keeps coming back, don’t just assume it is something you ate. For most people Cyclospora will be an unpleasant interruption to the summer rather than a serious illness.
