Further on medical transmission
I think medical procedures are indeed implicated in many cases of hep b or c. The more I think about this, the more I remember various readings, such as the hundreds of Egyptian dialysis patients who came down with hcv, or a study i stumbled upon (from latvia) that examined in-hospital transmission among children, and said, in part: "Hospital-acquired hepatitis B (HBV) and C virus (HCV) infections continue to occur despite increased awareness of this problem among the medical community. One hundred six patients were infected in a haematology oncology ward for children, over the time period 1996 to 2000."
And so on. In other words, where it's been looked for, it's been found. So, I think that the reassuring words we've heard on medical procdures NOT being the vector of viral spread may be true in large part, especially nowadays as health care workers are trained and re-trained, but the exceptions are apparently more than a few, and they are important. And, for every year we look back in recent history, I'll bet procedures were less and less absolutely safe.
With all the mysterious "no risk factor" cases out there in the US population, maybe our medical brethren should not be so quick to excuse their own industry, and therefore, their colleagues and themselves from the causation chain.
My opinion only. (of course)
