Sharp rise in cyclospora infections linked to Mexico travel

• Cyclospora infection cases have increased sharply among travellers with recent Mexico travel history; clinicians should maintain heightened diagnostic awareness and take travel history when investigating persistent diarrhoea with cyclosporiasis features
• Patient education on strict food and water hygiene precautions—including avoiding uncooked produce, untreated water, and eating only at established establishments—is essential for travellers to endemic areas
• Early recognition and treatment with trimethoprim-sulfamethoxazole is important, as cyclospora causes prolonged diarrhoea; standard antidiarrhoeal agents should be avoided due to risk of prolonged infection
