I walked ito my news agency on New Year's Eve, where the owner, engaged in conversation with a customer, coughed her lungs out. No covering of mouth. I was there for maybe a minute, sick the next day for a whole week.
I suggested to my husband that he sleep in another room, but he felt he'd be alright.
So with wads of tissues I went to bed, and if ever I coughed i covered my mouth and went to the bathroom
He didn't catch it, thankfully. Basic hygiene goes a long way to protecting each other.
Staying at home? Even better.
