医院感染多数为病原体通过手直接或间接接触性传播所导致,有研究证明经医务人员的手传播细菌而造成医院感染约占30%[1]。大量的科学研究已经表明,借手传播造成医院感染远比空气传染更具有危险性。大量的流行病学调查也表明[2,3],正确的洗手是预防和控制病原体传播,进而降低医院 Nosocomial infections are mostly caused by the direct or indirect contact of pathogens with sexually transmitted pathogens. Studies have shown that nosocomial infections account for about 30% of the total number of nosocomial infections transmitted by medical staff. A great deal of scientific research has shown that it is far more dangerous to transmit a nosocomial infection by air than airborne. A large number of epidemiological investigations have also shown that [2,3] the correct hand washing is to prevent and control the spread of pathogens, which in turn reduces the hospital
