Hospital infections occur from complex interactions between the host,the pathogen,and the environment.A large number of investigations have confirmed that the environmental surfaces close to patients(such as bedside tables and bed railings)are contaminated by microorganisms of epidemiological significance such as VRE and MRSA,which can survive on various environmental surfaces in hospitals.Therefore,effective surface cleaning and disinfection is the key step to reduce cross-contamination and control hospital infection.
Skin disinfection refers to killing or removing pathogenic microorganisms on human skin and meets disinfection requirements.Mucosal disinfection refers to the process of killing or eliminating pathogenic microorganisms in oral,nasal,vaginal and external genitals,and meets the disinfection requirements.At present,the commonly used complete skin disinfectants include iodine,guanidine,alcohols,quaternary ammonium salts and their compound preparations.Common disinfectants for mucous membranes include povidone iodine,chlorhexidine gluconate,chlorhexidine acetate,etc.
