I was asked for my opinion in here, so here it is. I think worrying about your mail is completely unnecessary. I still have to go to work, my kids are still going to school, not everyone has the luxury to be able to barricade themselves inside their homes. Wipe you mail down with disinfectant wipes if it concerns you, keep your hands clean...this too shall pass. Live your life.
I'm not participating in the game box train though, so what I think doesn't really matter.
