Abordaje epidemiológico en establecimiento de estancia prolongada de adultos mayores con antecedente de brote de COVID-19.
2021
INTRODUCTION: During the coronavirus disease pandemic (COVID-19), elderly people in long-term care facilities and their health workers constitute a vulnerable subpopulation with a high risk of hospitalization and death. The objective is to describe the epidemiological approach carried out in a long-term care facility for older adults under active surveillance, in the Mar del Plata-Batan urban area, on December 2020. METHODS: The approach strategy combined the indication to isolate suspected cases, perform RT-PCR and detection of IgG antibodies. RESULTS: 4 detectable results were obtained by RT-PCR for SARS-CoV-2 corresponding to health workers; only one had a history of RT-PCR detection during the initial outbreak that occurred 95 days previously; results in residents were undetectable. There were 40 cases with IgG type antibodies (63.5%); 12 (30%) had no history of detection by RT-PCR in any of the outbreaks. DISCUSSION: Findings indicate that having had a first outbreak episode at the facility conferred immunity on people who had no clinical signs of the disease, possibly preventing the second outbreak from spreading among residents.
