Ah, yes. We certainly hope this type of decision gets to be the norm. Notice that the doctor uses the liver transplant info as a timeline indicator for how long the Vet was infected. This is becoming more accepted by VA now with Metavir or Child’s ratings of your biopsy. This may become the yardstick for proving the age of the infection.

In a November 2009 statement, an IME indicated that, the  Veteran served in the military, during three time periods  between 1955 and 1976, and received numerous vaccinations, at  least some by air-gun injection; that he was diagnosed with  hepatitis C in 1995; and that, prior to that time, he denied  any behaviors, exposures, or risks that would transmit  hepatitis C.

Therefore, the exact date of hepatitis C infection is  impossible to determine, although acquisition of the  infection in the 1950s or 1960s would fit with the history of  progression to end-stage liver disease in the 2000s.  The IME  added that the transmission of hepatitis B via air-gun  injections has been well documented in the medical  literature.  Transmission of hepatitis C has not been, never  been, clearly documented to be related to use of such  devices, although the VA’s own Medical Service stated in 2004  that transmission of hepatitis C in this way was  “biologically plausible.”  The IME agrees with this  statement.  Therefore given the information available to him,  the IME believes that “it is highly likely that the  [V]eteran acquired [h]epatitis C between the 1950’s and  1970’s, encompassing the time of his military service, and  given the absence of any other know[n] risk exposures or  events it is as likely as not that this exposure was due to  the use of jet gun injections.”

Pretty straight forward, huh?
