Cyclospora is a common parasite found in parts of:
- Central and South America
- south and southeast Asia
- the Middle East
- Africa
You cannot catch it from close contact with someone who has it.
How to avoid cyclospora while travelling
If you're travelling to an area where cyclospora is found, there are things you can do to reduce the chances of getting it.
Symptoms of cyclospora
Not everyone with cyclospora gets symptoms. If you do get symptoms, they usually start about a week after getting infected.
Symptoms of cyclospora include:
- diarrhoea
- loss of appetite and weight loss
- stomach cramps
- bloating and farting
- tiredness
- feeling sick
- muscle aches
- high temperature (fever)
Urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if you have diarrhoea and you have recently travelled abroad and:
- you have diarrhoea that is severe and has lasted for more than 3 days
- you have bloody diarrhoea or bleeding from your bottom
- you have a high temperature (fever)
- you are dehydrated
- you have a weakened immune system or other condition
You can call 111 or get help from 111 online.
If you're still abroad, get medical advice where you are as soon as possible.
Treatment for cyclospora
Cyclospora usually gets better on its own within a few days or weeks. People with a weakened immune system may be at higher risk of more severe symptoms. Make sure you have lots of fluids to avoid dehydration.
Sometimes you may be asked to provide a sample of poo (stool sample) so it can be checked for cyclospora.
If your symptoms are severe or do not go away, you may need antibiotics.
