Here are my main takeaways from that experience for ordinary people on the ground:
1. Wash your hands frequently.
2. Don’t go to the office when you are sick. Don’t send your kids to school or day care when they are ill, either.

Notice I didn’t say anything about masks…
[O]utdoors, infections don’t spread well through the air. Those photos of people walking down streets in China wearing masks are dramatic but uninformed. And remember if a mask has, perchance, intercepted viruses that would have otherwise ended up in your body, then the mask is contaminated. So, in theory, to be protected maybe you should use a new one for each outing.
