Elderly people are susceptible to this new strain of coronavirus pneumonia because of their weaker resistance, so it is extremely important that they are protected and disinfected on a daily basis. Since the respiratory tract of the elderly is more sensitive and fragile, if there are no patients at home, it is sufficient to do a good job of daily protection. If disinfection is necessary, choose products that are less irritating to the respiratory tract, such as 75% alcohol pads or alcohol, and choose povidone-iodine and other chlorine-containing disinfectants to disinfect hands and skin. If the elderly suffer from asthma, chlorine-containing disinfectants may have an impact on them and need to be carefully selected. In addition, it is important to wash hands regularly, wear masks, exercise moderately, and keep the living environment clean and indoor air circulating. Source: Dr. Yurai
