Still no signs of parasite in water
Authorities are still hunting to find out what's caused more than two thousand people to report suffering stomach problems in the northern Swedish city of Skellefteå this month.
Twenty-four people there have so far been confirmed to have been infected by the stomach bug, Cryptosporidium. That's the parasite that contaminated Östersund's water supply for some three months this winter.
While water treatment plant tests have so far come back negative, the Swedish Institute for Communicable Disease Control says it's very likely that the drinking water is what's spreading the bug. Residents are still advised to boil tap water before drinking it.
