We will never know how they got it. There is even a possibility that someone who hates them deliberately infected them...we will never know.

Would a mask have really helped? Don't Know!
Did they get it on their hands and touch their face? Don't know!
Did someone deliberately infect them? Don't know!

What we do know is that masks are a double edged sword and that we should socially distance, wash hands and not touch our faces.

I have seen cashiers pick their noses through the disposable blue masks and then handle change and grocery items.

I have not seen any guidance on how often to wash homemade cloth masks or how often to change disposable masks.

It hardly helps to tell someone to use a mask when there are so many ways that they could fail or go wrong.

I have seen all the complaining about people not wearing masks at campaign rallies but I have not seen ANY statistics about how many maskless rally goers got infected within days of going to the rallies.

Where is the science data on this and how did the Trumps really get the infection?

I wear masks when I leave home and get out of the car but their is no way that I can know if the mask has the virus on it and have not seen any science on this.
