经历了三年疫情，竟然还有去别人家爬梯要不要脱鞋的讨论？

二十几年前，刚来美国的时候，看见过一篇调查，美国人90%饭前不洗手，50%便后不洗手。
三年疫情，这个比例下降了一半多。全世界死了几百上千万，美国也死了上百万，多数人家都提升了抑菌消毒的等级，洗手液遍布各处。
连手都每天消毒几次，何况鞋？每天穿着室外的鞋到处走，鞋底的泥沙灰尘可以携带大量致病菌和病毒，你回家不换鞋？你好意思去别人家不脱鞋，到处走？你还好意思穿着室外鞋在人家地毯上到处走？
即使是地砖或者木地板，室外鞋底带着的泥沙灰尘照样到处留痕，也就是病菌病毒给人家地板上到处留。相比于地毯，只不过接触面积少一些，留的少点罢了。
这都神马人啊？不可思议。 ———————————— 另：对我主帖负责，查了一下，鞋底带菌42万unit，并且主要是大肠杆菌；鞋内仅带菌不到3千unit。
Charles Gerba, microbiologist, and professor at the University of Arizona, there is an average of over 421,000 units of bacteria on the outside of our shoes, also known as the soles of shoes. In addition to this, there are over 2,887 units of bacteria on the inside of our shoes.
“Bacteria, including E. coli, is found on the majority of shoes," says Cindy Gellner, MD, a pediatrician at University of Utah Health. "Your shoes come in contact with bacteria from restroom floors and the outdoors. Unless you remove your shoes or clean them, you can transfer the bacteria indoors.
