Outbreak News Today reports UK health officials are seeing an increase in the parasitic infection, cyclosporiasis, in travelers returning from Mexico, according to Travel Health Pro report.

The cluster has been seen since June and many of the travelers stayed in Riviera Maya, the same place where some 80 travelers contracted Cyclospora last summer.

Cyclospora has been implicated in numerous outbreaks with contaminated fruits and vegetables being the common culprits (raspberries, basil and lettuce all washed with contaminated water), especially those imported from developing nations.

All fruits and vegetables should be thoroughly washed before eating though this does not guarantee safety. Cyclospora is resistant to chlorination.

Treatment is usually successful after a course of the antibiotic Septra.
