The ND Department of Health has stated that the HCV isolated from infected persons is genetically related and epidemiologically linked to the nursing home. The data coming from the investigation is minimal at this point, and I haven't seen anything reported on what they think the source is.
If you have questions, please use the comments section below!
HCV is typically transmitted by blood contact via transfusion or shared needle/sharps exposure. There have been past cases of HCV or HBV, hospital-acquired infections (iatrogenic) relating to glucose point of care testing, dialysis centers, or medication contamination by drug-abusing health care workers.
I will definitely be watching this outbreak closely. Hopefully a source can be determined.
