New regulations concerning EHEC/VTEC

New regulations concerning EHEC/VTEC Hemolytic Uremic Syndrome (HUS) is the most severe complication to an infection with EHEC (enterohemorrhagic E. coli), also called VTEC (verocytotoxin-producing E. coli). Risk of severe complications such as HUS is an important reason why the Swedish Communicable Diseases Act (Smittskyddslag. 2004:168) includes infection with EHEC. With very few exceptions, only EHEC with the stx2 gene is associated with HUS. According to the law, persons working with unpackaged foods, infants or severely immunocompromised patients, and children attending preschool can be suspended awaiting negative test results for EHEC. Symptom free carriers of EHEC-infection only harbouring the stx1 gene and without an epidemiological association to HUS need not be suspended from work or preschool.
