What is over disinfection?
Experts from the Center for Disease Control and Prevention explained that this refers to repeated disinfection in places that are seldom contaminated by pathogens and are not necessary for disinfection, or to insist on using certain ineffective disinfection methods. The most important feature is "not necessary."
"Disinfection is an important means to cut off the transmission route and control the epidemic of infectious diseases, but it should not be excessive."
With the increase of citizens’ awareness of epidemic prevention, excessive disinfection has recently appeared in some places.
