The Grand Rapids doctor who went viral for showing us all how to safely handle our groceries is back with more safety tips... this time with mail, package and deliveries.

Dr. Jeff VanWingen says that COVID-19 can live on cardboard for up to 24 hours so when opening a package, empty the contents without touching them. Then take the box back outside to throw in the trash. And you already know the next step... wash your hands!

Try and wait a day before getting your mail, otherwise, set it aside for later.

Dr. Jeff even shows you what to do when you get a pizza delivered.

Something to keep in mind is he's demonstrating "worst-case" scenarios, so you can take all these extra steps if you want to be super cautious.
