- Wash your hands thoroughly
- Don’t touch your eyes, nose or mouth with unwashed hands
- Avoid sick people
Ok, that’s nice, but how do you do the latter, how much care should you exercise. Well, in the US, it’s not the norm, but in Asia, everyone pretty much wears a mask because although there might be a false sense of security, it does prevent you from some aerosols and keeps you from rubbing your eyes, nose or mouth.
Given that the thing is so contagious, we are “abundance of caution people”, so we do wear a mask and are very aware of what is clean or not. So YMMV, but if you have one, don’t get carried away and used properly it can’t hurt.
As the WHO says:
- If you are healthy only wear it if you suspect someone has Covid. In the US, with such limited testing, well that’s just about everyone you see.
- Wear a mask if you are yourself coughing or sneezing
- If you wear a mask, then you still have to wash every time you go to a sanitary zone (eg your home).
- It should be obvious but put it on after you wash your hands.
- When you take it off, take it off from the back. That is, wash your hands, then remove from the “clean” inside.
We also have some other precautions, like they do in Singapore, when you come to your home, have a “dirty area” where you do this. We also shed our clothes there (which is why everyone in Asia has a cheap raincoat on all the time and glasses to cover your eyes).
