She drove to work and parked as close as she could to the hospital entrance. In the car, she put on a surgical mask as they have to have a mask on when they enter the hospital. Because of the windchill factor, she had to put on a hat that covered her ears, and she put a scarf over her mask for extra coverage of her nose and rest of her face so that not much of her face would be exposed. She said she kept two new/clean masks in her bag so that she could change out her mask as soon as she could when she got inside because the masks freeze on the outside and then are not effective - they stay moist on the inside due to your breath that stays warm on the inside of the mask, but the outside freezes when it gets wet, although the scarf wrapped around her head helped. Also, with the cold air, often people get a runny nose, the whole thing is quite unpleasant, and you have to change masks quickly as soon as you can. Once it gets wet like this, the mask will not stop viral droplets from escaping or from entering.
That's pretty much it. Today is her birthday, and she is glad to be home where it's warm and cozy and no masks required.
