Cryptosporidiosis outbreak in Ohio, USA, continues to increase

Since an outbreak of a parasitic infection called cryptosporidiosis was reported in August, there has been a steady increase in people infected with this parasite in Columbus, Franklin and Delaware counties. So far, slightly more than 1,000 people have been infected through exposure to the parasite at various recreational water facilities throughout the three jurisdictions.

Advice For Travellers

Cryptosporidiosis is caused by a parasite that is found in fecally contaminated water. Swallowing contaminated water results in watery diarrhea, abdominal pain and cramping, which may be accompanied by dehydration, weight loss, fever, nausea and vomiting. Symptoms can last for two weeks. Improvement may be followed by recurrence. Infected persons can continue to spread the disease for several weeks after diarrhea subsides, so they should avoid activities involving recreational waters for at least two weeks after diarrhea subsides and practice diligent hand washing.

Travellers can minimize exposure by avoiding swallowing water when swimming in recreational waters.
