If he was infected, so were others standing in line and that is something which can be determined.
The usual route? I got my Hep C in my teens before blood was screened. From a blood transfusion! I didn't even know I had it until I tried to give blood in 1982 & was told I had non A non B Hep. There wasn't even a C back then. You can get Hep C many ways & not just from drug use or sex.
Certain specialized risks have also been identified - such as manicures, shared toothbrushes, or straight razors in barber shops.

That's what used to be thought of Hep. B. I'd never engaged in the behaviors associated with Hep. B yet I got it. Likely in a hospital.
Uh huh. I don’t know HOW I got it. Risk factors included blood transfusion and a stint in the healthcare industry with direct patient contact [before everyone started wearing latex]....
To this day, it is appalling at how many people think only needle addicts get Hep C.
