Cyclospora most often occurs in tropical and subtropical regions of the world including:
- South America
- Central America
- South Asia
- South East Asia
- Middle East
Most recently UK travellers to Mexico have been affected.
Symptoms usually start one to seven days after the parasite is ingested. Infection causes watery diarrhoea that can last for days to weeks, and recur. Tiredness, loss of appetite, nausea, stomach cramps, mild fever and weight loss may also occur. Infection can be more serious in those with a compromised immune system.
Visit the NHS Inform website for information about the symptoms and managing gastroenteritis.
