Maybe he is infected, but if he is then he's taking his sweet time to turn. Zoe re-attached the arm and probably put some of that magic medical juice on it or something but that's just speculation at this point. All RE protagonists take tons of damage from things that would kill anyone of us. They try to do the same thing to Clancy in the Banned Footage dlc.

Then why would the family want him to eat the infected food? That is how they infect people, with the food (and probably exposure to Eveline over time according to some notes).

Not every pharmaceutical item has to have an evil purpose. I mean like it only makes sense that something like this would exsist in the Resident Evil universe considering everything else. Besides even if what they claimed was true, it wouldn't make sense why he would even pour on something to help him heal faster if the virus already heals wounds nearly instantly. I don't know if the the two people above me are right about their claims but Ethan uses these items before even encountering any of the family members or Molded enemies and it says the same thing.

If you go into your inventory and select the first aid med, it will tell you that in the description.
