I was surprised to hear how many audio effects there are :D Pretty cool concept although there's not much to do right now. I flipped the light switch a couple of times and got 40 contaminated objects from that. Then I touched some stuff on my way to see them turn green. I ate food to get a virus. I washed my hands, did some work on the computer and went to sleep.
It would be really cool if you were given some tasks like preparing meals, having to work x amount of time one day or something else that pushes the player to actually try different things.
