Ethics approval and consent to participate
: The study was approved by the Regional committee for medical and health research ethics (REC) South East, Norway (Approval number: 2009/849) with a dispensation from consent from participants as (a) it is difficult to get consent from this patients group (migrants, drug users), (b) the data was already available in the notification system and the lab analysis was performed prior to the start of the study, (c) some samples are old why it will be very hard to trace the patients, (d) any patient contact was made between the patient and the responsible medical doctor who sent inn samples for genotyping analysis before the project started. Personal identification was only needed to link origin and route of infection to the sequence. Linkage between patient data was only made temporarily whereafter all data, and subsequently all publicly available data, was anonymised.
