Didn't realize horses could get hepatitis. Huh! In humans at least, it is very contagious.Back in the day docs had an autoclave for sterilization.... all instruments went in including needles... NO ONE uses them any more... I remember watching the stable manager use the same needle on eight horses rinsing it out with Alcohol... Giving immunizations.
The mare I had that was taken back by her original owner died of Hepatitis... I didnt put two and two together till twenty five years later.
