手洗い励行

2. If you are in a social situation where you should remove your gloves, perhaps to shake hands or dine, do not touch your face or eyes, no matter how much something itches. Keep your hands away from contact with your face. And before you put your gloves back on, wash your hands thoroughly with soap and warm water, scrubbing the fingers. Put your gloves on.

顔に手を付けないこと、そして、手洗いをよくすることだな。
