Care homes and COVID-19 in Hong Kong: how the lessons from SARS were used to good effect

Abstract In Hong Kong, about 15% of older people (aged 80 and above) live in care homes, one of the highest proportions in the world. During the spread of severe acute respiratory syndrome in 2003, the crude fatality rate for older people in care homes that were infected was 72%. After taking the advice of a team of international experts, the Hong Kong Government implemented comprehensive preventive measures to cope with the future epidemics. This commentary evaluates the effectiveness of these measures in coping with both influenza outbreaks and COVID-19 and suggests the lessons learnt are relevant to both developed and less developed countries? Lockdown in care homes is very effective under two conditions. Healthcare workers must wear surgical masks in the care home. Hospitals must adopt a strict policy to prevent virus transmission by discharged patients. Care homes situated within high-rise residential towers are particularly vulnerable to COVID-19 transmission; their residents can more easily be infected by asymptomatic carriers from the community. Airborne virus can also be transmitted more swiftly in care homes with open-plan layouts. Lockdown had been shown to significantly reduce influenza outbreaks in care homes. On the other hand, lockdown causes loneliness to residents. Care homes allow residents to move freely within the care home though with the risk of spreading the virus by resident who is an asymptomatic carrier. Finally, lockdown may cause family members to have guilty feelings. Family members can only make video call or window visit to residents.
