Unfortunately even if we could get everyone to be tested, not everyone can take the meds. I had to take a profilact dose after an accidental needle stick when I was a student nurse. The starps box was next to the light switch, and whomever collected the patients blood did not make sure the needle was actually inside the box. That medication made me feel like I was dying, and that was only for a couple of weeks. Newer better meds have come out, but there are always those people that can't take those meds.
