You completely ignored human error aspect. Before the blood donation centers used one time use equipment, donors were getting infected with something nasty every now and then. You can sure as hell expect people to commonly forget to properly sanitize those syringes.

Sterilization is* the most strictly controlled process in any hospital. Nobody can just "forget" to sterilize or pick up a used syringe thinking it's sterile.

* Or at least it should be. It seems that Pakistan is different.

As aviation has shown—where human error has been studied for decades—reducing mistakes is difficult and expensive because it requires multiple layers of quality assurance. In countries where labor is costly, especially in healthcare, it has got to actually be cheaper to use single-use equipment, with the added benefit of reducing the risk of infection through that route to zero.
