Prevention of health care-associated infection is an important issue for healthcare facilities and the World Health Organization. Correlations exist between the cleanliness of hospital environments and health care-associated infections. Therefore, cleaning and disinfecting the environment to reduce pathogens is highly important. Conventional manual cleaning could not effectively disinfect the repeatedly polluted hospital environment. Dry mist or vapor cleaning in which disinfectant H2O2 is sprayed to create small particles that could reach to all surfaces is an emerging method of cleaning to eradicate environmental pathogens effectively and has now been more emphasized. The automated disinfection program using small-particle H2O2 is far more effective for cleaning the environment, especially the drug-resistant bacteria such as methicillin-resistant Staphylococcus aureus and Clostridium difficile, than manual cleaning. Compared with other toxic, environmentally hazardous cleaning agents, H2O2 provides an alternative and can effectively clean and sterilize closed environments such as isolation wards, clean rooms, equipment, and other places contaminated with pathogenic microorganisms. The application of H2O2 dry mist or vapor could be further expanded to include other environmental cleaning and disinfection. |
