My school was worried about me going to Africa and putting myself at risk, but the truth is, it could as easily happen here. In Montreal we don’t, for example, use the self-sheathing syringes he cites as a great improvement, we use the old-fashioned and appreciably cheaper sort that they also use in the UK.
In Malawi, we had the other type. Due to the perception of the risk, no doubt. I liked them.
