More cholera discovered in Swedish waters
Swedes are being warned that there is cholera in lakes in many parts of the country, as well as in sea-water along the coast.
Three people were found to have caught the disease last week after bathing in the south of the country.
Since then, university researchers have discovered the water-borne disease in several other areas.
According to the newspaper Dagens Nyheter, people are being advised not to swim if they have open sores, even in fresh water.
The risk of being affected by the bacteria is said to be low, but the warm weather has made it higher.
