アメリカ疫病予防管理センター「アメリカ人よ！家では靴を脱げ」　まさかのテイクオフシューズ（靴を脱げ）運動開始

Medical workers on the front lines of the coronavirus should be sure to clean their shoes.

In a new study published in one of the Centers for Disease Control and Prevention’s journals,
Emerging Infectious Diseases, researchers tested air and surface samples at a hospital
in Wuhan, China, where the coronavirus outbreak initiated. The researchers found that about half
of health-care professionals working in intensive care units carried the coronavirus
on the soles of their shoes. Further, the report showed that there was a 100% positive rate
from the floor of the pharmacy, where only health-care workers traveled, not infected patients.
