I can understand the desire to reduce needle-sticks to healthcare workers and the reuse of needles which cause infections, but even those with disposable spacers/cartridge may not be as risk-free as single dose, single-use syringes.
I’m going to include these slides in my DHs claim for HCV because they’re authoritative, short and to the point.
“Risk of transmission” is stronger language than the Fast Letter’s term, “plausible.” They have evidence that they do transmit bloodborne pathogens. Also note that MUNJIs were sterilized nightly, not after each arm-to-arm injection.
