От знакомого рисерчера-вирусолога с востока:
As young adults we are pretty safe. Mainly the elderly are at risk and those with respiratory diseases. So the lesson is: tell your grandparents to wear masks, wash your hands, dont cough into them (use your clothes or elbow), drink plenty of fluids and wear a face mask when out in public
Is there a big difference between using the blue facemasks and n95 respirators in preventing infection for a virus like this? - n95 are more powerful but either one should do the trick.
