Nursing homes have suffered in a particularly pronounced way from the effects of COVID-19 so it is very convenient to know the evolution in them of the disease and the impact of SARS-CoV2 vaccination The objective of this study was to analyze COVID-19 pandemic evolution from the start of the second wave to the end of the vaccination campaign at the nursing homes. A coordination program between Primary Care and Geriatrics and Public Health services was activated.
2,668 seniors were followed at 39 nursing homes. Data from new cases, active cases, mortality and place of treatment of COVID-19 were collected. A descriptive analysis was performed with the measurement of the absolute number of positive SARS-CoV-2 cases and the frequency distribution.
Between August 7 2020 and February 26 2021, 30 outbreaks occurred at 21 nursing homes. 300 people tested positive for SARS-CoV-2 (11% of total residents). The daily average of active cases was 27,166 were hospitalized (55%). 66 patients died (22% of those infected), 54 of them (78%) at the hospital. 1,984 PCR tests were performed. The temporary profile of new cases did not follow a distribution "in waves" as in the community. Thirty-seven days after the start of the second dose of vaccination, there were no active cases until March 1, when new cases were under study for possible vaccine leakage.
The incidence of COVID-19 at nursing homes after the first wave of the pandemic has apparently been lower. The transmission in these centers has followed a different distribution than at community. Mass vaccination has achieved the practical disappearance of the disease.
养老院受新冠疫情影响尤为严重，因此了解该疾病在养老院中的发展情况以及新冠病毒疫苗接种的影响非常有必要。本研究的目的是分析从第二波疫情开始到养老院疫苗接种活动结束期间新冠疫情的发展情况。启动了基层医疗、老年医学和公共卫生服务之间的协调项目。
对39家养老院的2668名老年人进行了随访。收集了新冠疫情的新病例、现患病例、死亡率及治疗地点的数据。采用描述性分析方法，测量新冠病毒阳性病例的绝对数量和频率分布。
2020年8月7日至2021年2月26日期间，21家养老院发生了30起疫情。300人新冠病毒检测呈阳性（占总居民数的11%）。现患病例的日均数为27例，166人住院（占55%）。66例患者死亡（占感染患者的22%），其中54例（占78%）在医院死亡。共进行了1984次聚合酶链反应检测。新病例的时间分布不像社区那样呈“波浪式”。第二剂疫苗接种开始37天后，直到3月1日都没有现患病例，当时正在研究新病例是否可能是疫苗接种后出现的情况。
第一波疫情后养老院中新冠疫情的发病率明显较低。这些机构中的传播分布与社区不同。大规模疫苗接种已使该疾病实际消失。
