An inventory would greatly increase the longevity of gameplay, and additional items are always a good thing.
I got the Handsanitizer and Lysol already working in a more complete version. They would have been here but the collisions were acting up and I wanted to make 100% sure NPCs were not spawning inside buildings and stuff before all else. I feel the final death state for the NPCs is crucial before adding the sanitizer and lysol because I do not want to make it to easy either so I figured NPCs can run around sick for a period of time then "die" at which point if you touch them you are dead no matter what.
