I had vague recollections of Giardia and Cryptosporidia, but I was not able to recall any specific signs and symptoms beyond generic gastrointestinal complaints.

Water-associated health complaints may occur despite the fact that the microbiologic quality of the bathing water complies with European Union (EU) Directive 76/160/EEC (1976), which sets limits for fecal indicator bacteria and is primarily aimed at protecting the bather against gastrointestinal complaints and acute febrile respiratory illness, but not against eye, skin, and ear complaints.

One can underwrite garden-variety histories of arthritis, headache, fainting and gastrointestinal complaints via sound teleunderwriting, but it would be correspondingly daft to do likewise with malignant melanoma and coronary artery bypass surgery.
