RESUMO
The impact of the pandemic of the new coronavirus infection Covid-19 and the introduction of self-isolation on the quality of life of the older generation 65+ were analyzed, with an assessment of herd immunity among the study participants. The study protocol included 192 people who are employees of the Irkutsk Scientific Center, including 94 people of the older age group 65+. All participants were divided by us conditionally into four age groups. The age of the examined patients ranged from 21 to 88 years. At the first stage, the results of filling out the EQ-5D-3L took part with an assessment of the health profile, reflecting three levels of problems in five components. On average, the EQ-VAS quality of life indicator decreased a year after the pandemic compared to the data obtained after a month-long period of self-isolation. According to the respondents, it was the presence of disturbing information and the level of emotional tension in society that became decisive in answering the questions of the questionnaires. When assessing population immunity to the SARS-CoV-2 virus, a positive trend was revealed during the study period of 2021-2022, mainly due to vaccination activities, the number of ill participants in the study tended to decrease. As a result, population immunity to the SARS-CoV-2 virus was 77% in 2021 and 87% in 2022. In 2021, the maximum seroprevalence level was detected among the age group 60-80 years old (83.5%), and in 2022 - in the group 40-60 years (93%).
