Public items in public places are generally disgusted by people, and they think that many people have the possibility of cross-infection of bacteria, but most people will not refuse to use hand sanitizer to absorb them, and use a dryer to dry them after washing. Dry it, and feel that these items either have disinfection and sterilization effects themselves, and no bacteria will be stored in them, or think that they are non-contact items, and there is no possibility of poor infection of bacteria if everyone does not touch them.
Is this really the case? Some people have sampled and checked relatively hygienic toilets such as airports and hotels. The results are surprising. The bacteria in some toilets have exceeded 600 times the standard, and the dryers will inhale the environment because they need to inhale and then blow them out. A large amount of bacteria are sprayed on the hands, and it is better not to wash after washing.
Actually, there are many misunderstandings about bacterial content in life. For example, there are more bacteria on mobile phones than in urine, the odor in the mouth is no less than that of a big man’s feet, and the air in the hospital No matter how to disinfect, bacteria are flying all over the sky. Doctors catch more colds than normal people every year. Sometimes they do blood tests related to tuberculosis, and the positive degree is higher than that of some tuberculosis patients.
So what else looks clean but is really dirty? Let’s all discuss.
