Nowadays, there are some public places where low-immunity people gather, such as special wards of hospitals, kindergartens, primary schools, and the like. People do not pay attention to the object surface disinfection work in the public places for a long time, and diseases transmitted by contact can be given opportunity. Take Intensive Care Unit (ICU) as an example; in hospitals today, ICU patients are in an environment of multiple drug resistant bacterial infections. ICU medical personnel work load is big, personnel are not enough relatively, mobility is big etc. factor very easily causes hospital surface object to receive virus infection, and clinical microorganism ecological environment is complicated and easily exceeds standard, and important pathogenic microorganism can survive considerable time on clinical environment object surface, wherein although nursing staff's aseptic concept is stronger, can carry out aseptic operation betterly, but sanitary personnel lack such general knowledge more, and the cleaning to the doorknob is not enough, has consequently caused certain hidden danger.

Evidence has been observed showing that environmental object surfaces play a significant role in the spread of nosocomial infectious pathogens during a nosocomial infection outbreak. Tests show that the disinfectant used on the surface of an object has the possibility of completely blocking hospital infection, and the deep continuous disinfection can reduce the load level of pathogenic microorganisms, block the spread of the pathogenic microorganisms and be beneficial to controlling the outbreak and epidemic of the hospital infection. This therefore also indicates that door handle sterilization is of some significance.

Most hospitals select a traditional disinfectant for disinfection, but bacteria have three drug resistance mechanisms of self drug resistance, inductive drug resistance and acquired drug resistance to the disinfectant, and the use of a large amount of the disinfectant can cause the sensitivity of the bacteria to the disinfectant to be reduced, and the reduction speed is continuously increased. The experiment also shows that: disinfectant-resistant bacteria are present at higher levels in hospitals than in nature.
