During epidemics of novel coronavirus pneumonia, different guidelines have relatively clear recommendations on disinfection measures for novel coronavirus, and generally recommend inactivation of novel coronavirus by 56°C for 30 minutes. If disinfectants are used, 75% alcohol can be used, and chlorine-containing disinfectants such as 84 disinfectant and peracetic acid can be used. However, disinfectants containing chlorhexidine have no effect on the new coronavirus and are not recommended. Therefore, it is important to choose the recommended disinfectants when disinfecting at home. For healthy families, there is no need to over-disinfect the living room. Ventilation, hand washing and disinfection of surfaces in contact with the outside world are sufficient. Source: Dr. Yurai
