The primary way to become hep positive it through becoming reinfected an entirely new infection. This would happen for those who continue with risk taking practices like using IV drugs and sharing needles.
Having previously treated and cured hep c does not afford any future immunity.
A true late relapse long after successful treatment with the new DAA’s is while not unheard of is exceedingly rare.
One indication of either a true relapse or an entirely new infection would be a return to having elevated liver enzymes with no other known cause for this to occur.
The reason I ask is that I have fatty liver and they have done a lot of blood test and fiborscan and they said it all was normal but now just got a letter for Quantasure and the letter said HCV Infection B19. 20 very scare
I did find B19.20 is a diagnostic code used in medical billing it means “Unspecified viral hepatitis C without hepatic coma.“
Still no idea what this means in context of your situation without seeing your labs slip
