Three small children from Oslo, Akershus and Østfold are in hospital with a serious kidney disease following an E. coli infection.

Oslo University Hospital (Oslo Universitetssykehus) authorities confirm two have developed the potentially fatal Haemolytic-uremic syndrome (H.U.S.), which can also give acute kidney failure and change blood chemistry.

The Institute of Public Health (Folkehelseinstituttet/FHI) says the third child, admitted to Ullevål Hospital, has also developed H.U.S. Medical staff at both hospitals are refusing to give details about their conditions.

The Foreigner reports that no further details were available at this time.
