Developing methodical approaches to managing risks of airborne infections with aerosol contagion

A promising way to prevent spread of airborne infections with aerosol contagion and to reduce risks of healthcare-associated infections (HAI) is to preserve clean air inside premises (including medical organizations) via performing activities aimed at disinfecting air, ventilation and air-conditioning systems and via switching to up-to-date ecologically friendly disinfectants and their rotation. Epidemiological hazards for patients and medical personnel in medical organizations are caused by pathogenic and opportunistic pathogenic microorganisms that can be found in the air inside premises and on various surfaces; such micro-organisms are bacteria in their vegetative form (including tuberculosis agents), viruses, fungi that cause candidosis and dermato-phytes, mold fungi, spore bacteria. Aerosol disinfection is a well proven technique for treating the air inside premises in order to disinfect it and to reduce risks of infections spread; this technique involves transforming a disinfectant into a fine-disperse state with a specialized spraying device so that an aerosol is introduced into the air inside a premise. To work out efficient air disinfection regimes that involve application of relevant equipment and disinfectants, it is necessary to apply such techniques and conditions that would secure the most efficient application of aerosol disinfection in practical conditions. The authors have outlined basic organizational and methodical approaches to an objective assessment of how efficient and how safe aerosol disinfection technique is when it is applied in different premises, including medical organizations.
