At present, it has entered the epidemic period of respiratory infectious diseases, facing the risk of superimposed infection of influenza, mycoplasma and novel coronavirus. The elderly living in pension institutions are susceptible to respiratory infectious diseases in autumn and winter because of their low autoimmunity. At the same time, the elderly living in pension institutions are prone to cross-transmission and cluster epidemics. In order to do a good job in the provention and control of respiratory infectious diseases in old-age institutions in autumn and winter, the Beijing CDC has formulated special disinfection guidelines.
With regard to the principle of disinfection, the old-age institutions mainly focus on ventilation, cleanliness and hygiene, supplemented by preventive disinfection, focusing on disinfection objects including desktops, door handles, handrails, faucets, bed sheets, bedding, etc. Once patients with respiratory infectious diseases occur, ventilation should be strengthened, and the surface of environmental objects that may be contaminated should be strictly disinfected.
Indoor air is mainly ventilated by opening windows to maintain indoor air circulation. According to weather conditions, ventilation should be conducted 2 to 3 times a day, not less than 30 minutes each time. The elderly should pay attention to keeping warm when opening windows for ventilation. When ventilation conditions are poor, mechanical ventilation or circulating air disinfection machine can be used for air disinfection. If there are patients with respiratory infectious diseases, ventilation should be strengthened, and ultraviolet lamps and air disinfection machines can also be used to disinfect the air. Ultraviolet lamps should not be used under human conditions.
The surfaces of frequently touched environmental objects such as desktop, countertop, door handle, handrail, faucet, fitness and entertainment equipment can be wiped and disinfected with 500mg/L chlorine-containing disinfectant or other disinfectants that can be used for surface disinfection. Small items such as mobile phones, mice, keyboards, elevator buttons and emergency call buttons can be wiped and disinfected with 75% alcohol wipes. If there are patients with respiratory infectious diseases, 1000mg/L chlorine-containing disinfectant can be used to disinfect the surface that may be contaminated.
Towels, clothes, bed sheets, quilt covers and other fabrics are mainly cleaned, and can also be soaked and disinfected with 250mg/L chlorine-containing disinfectant or other disinfectants that can be used for fabric disinfection. Soak the fabric completely in the disinfectant solution for 15 minutes, and then wash it as usual. It can also be sterilized by circulating steam or boiling for 15 minutes. If patients with respiratory infectious diseases occur, they can be disinfected by soaking in 500 mg/L chlorine-containing disinfectant.
The guidelines also specifically remind a number of matters needing attention, suggesting scientific and moderate disinfection, standardized use in accordance with the disinfection product instructions, to avoid excessive disinfection. Disinfectants are irritating to some extent, so personal protection should be paid attention to during preparation and use, and masks and gloves should be worn. When carrying out disinfection, it should be carried out in the absence of people, and then enter the room after ventilation. Chlorine containing disinfectant has certain corrosiveness, pay attention to wiping with clean water to remove residues after disinfection, so as to prevent damage to the disinfected articles.
