I find in the UK, people pick up stuff on "Full View" look at it, and either put it back or put it down somewhere different, hoping someone else will replace it in its correct place or enclosure.
Humans have some strange things going on, or maybe its us that are to regimented in our thinking.
We now spray 100% disenfectant on everything with an outer cover on it and cardboard holding tins together, and multi buys together, which get dumped as soon as they come home, as its clear everybody has been touching everything and thats how it will get into your house. Safety First especially when it comes to where people congregate and touch everything including postal deliveries!!
Thanks for the update
