You are misinformed. Hepatitus C can be transferred (and was) by any invasive medical procedure like tehe Dentist or a Tatoo Parlor or medical surgery - before they used Autoclaving for sterilization.
Nothing kills the Hepatitus virus (or AIDS or Ebola) except Autoclaving which is like pressure canning, but has been adapted to sterilize metal equipment and tools.
It was found that the drill handsets Dentists used harbored viruses, though all their bits and attachments were 'sterilized'. Only AFTER the handsets and tools were Autoclaved after each use was it possible to not transmit previous patient's viruses.
And by the way, very good news is that Hyperbaric Oxygen Therapy puts Hepatitus in remission. It takes 24-35 essions but it regenerates the liver by angiogenesis, which is the creation of new cappilaries & arteries.
