A Scottish woman has been hospitalized after wild swimming with friends to celebrate a birthday. After the swim she returned home, only to fall ill the next day with stomach pains and fatigue.
Shelly Sim of East Lothian contacted her doctor, who recommended she go straight to hospital, where she remained for five days with severe gastroenteritis and dehydration. After running tests, the hospital diagnosed her with cryptosporidium, a parasite that causes a diarrheal illness that you can pick up by swallowing contaminated water.
