Pendant la troisième vague de la pandémie de COVID-19 à la fin de l’année 2020, des cas groupés sont apparus fréquemment dans les établissements de soins pour personnes âgées (ACF), ce qui a mis la pression sur le domaine médical au Japon. Sur la base de cette expérience, l’Université de Kyoto et la ville de Kyoto ont collaboré pour promouvoir une stratégie de prévention du COVID-19 à l’échelle de la ville afin de prévenir la propagation du COVID-19 dans les ACF. L’objectif de cette étude était de clarifier l’effet de la stratégie de prévention parmi les ACFs de la ville de Kyoto pendant les troisième et cinquième vagues de la pandémie.
Background During the third wave of the COVID-19 pandemic at the end of 2020, clusters occurred frequently in aged-care facilities (ACFs), which put pressure on the medical field in Japan. Based on this experience, Kyoto University and Kyoto City collaborated to promote a citywide COVID-19 prevention strategy to prevent the spread of COVID-19 within ACFs. The aim of this study was to clarify the effect of the prevention strategy among ACFs in Kyoto City during the third and fifth waves of the pandemic. Methods During the study period, the following measures were adopted as the prevention strategy in all ACFs: (1) active polymerase chain reaction (PCR) mass testing and facility-wide testing when a single case was identified, (2) implementation of strategies to prevent transmission within a facility, and (3) vaccination program for ACFs. Results Of the 1,144 facilities subjected to the mass testing, 71.0% participated in the whole program including active PCR testing. The remainder participated in the rest of the programs. The prevalence of ACF-related COVID-19 cases among total COVID-19 cases in Kyoto City decreased from 7.9% in the third wave to 4.1% in the fourth wave and 2.1% in the fifth wave. The incidence of clusters and proportion of severe elderly cases also decreased during the study period. Conclusions A city-wide multidisciplinary effort including PCR mass testing and a vaccination program in cooperation with a university and local administrative office successfully reduced the clusters and transmission in ACFs in Kyoto City, Japan.
