The Perth Leisure Pool was closed on 9 August as a precaution after eight children were taken ill.

Tayside Health Board had said there was no cause for alarm as cryptosporidiosis was usually a "very mild illness".

Cryptosporidium can cause severe diarrhoea, sickness, stomach cramps and a slight fever.

Water supply

The parasite sparked an alert in Glasgow and Clydebank following concerns about the levels in the water supply.

More than 150,000 people served by one reservoir were told to boil their water during the outbreak.

However, the outbreak in Perthshire was not linked to the public water supply and was believed to have originated as a result of faecal contamination.

The pool is run by Perth and Kinross Leisure on behalf of Perth and Kinross Council.
