No, you generally cannot get Hepatitis A twice because a past infection creates lifelong immunity, but in very rare cases, a temporary "relapsing" hepatitis A can occur, where symptoms reappear after a period of improvement, though full recovery with lifelong protection usually follows. You can't get reinfected with the same virus, but sometimes the liver inflammation can seem to come back for a few months before resolving completely.Can I kiss someone with hepatitis A?

The virus spreads via fecal-oral route through contaminated food, water, or person-to-person contact.Which hepatitis is not curable?
