“…In the mental health aspect of our study, the means were considered as having good QOLin both states, which demonstrates that this population is enduring the moment of social isolation in their homes. Possible psychiatric problems intensify with psychological wear, thus increasing the suicide rate [35][36][37] .…”

Introduction: COVID-19 is a highly transmissible virus that is causing very serious problems in the health of the world, generating major political and financial problems. There are numerous risk factors related to this disease, ranging from morbidities to social and family issues. Objective: to evaluate the effects of the social isolation generated by Covid-19 on the quality of life in the population of two Brazilian cities. Methods: cross-sectional study. The research was carried out in two different cities of the Brazilian confederation. One in Santo André, São Paulo and the other in Rio Branco, Acre, both in Brazil. This is a survey with an online platform, using the drive’s Google Forms tool to assess the population’s quality of life through the SF-36 protocol. The selection was carried out randomly in both groups (Acre and São Paulo), having respectively 109 and 62 participants in this first moment. Results: regarding gender, women are in greater numbers participating in the city of Santo André, São Paulo than in Rio Branco, Acre, both in Brazil, with (80.6% and 48.6%), respectively. Likewise, in relation to the age group Santo André has an average age younger than in Rio Branco. When we compared the dimensions between the two states, performing a Mann-Whitney statistical analysis, statistical differences appeared in three dimensions, which were functional capacity, pain, and vitality, with better quality of life in these three domains for the city of Rio Branco. Conclusion: the city of Rio Branco, Acre, Brazil, has a positive score when compared to the city of Santo André, São Paulo, Brazil, in most of the domains analyzed.

Introduction: the growth of coronavirus indices in the North region highlights the region’s historical social inequalities and the problems in accessing citizenship. Objective: to analyze the mortality and lethality of COVID-19 in the state of Pará, Brazil. Methods: this is an ecological study with a time series design of secondary data. All registered cases and deaths reported by COVID-19 in the period from March 2020 to June 2021, in the state of Pará, Brazil, were considered. The incidence and mortality and lethality rates were used. The daily percentage variation and their respective 95% confidence intervals were estimated. Results: the total number of confirmed cases and deaths from COVID-19 in the state of Pará was 552,937 and 15,469, respectively, from March 2020 to June 2021. Incidence and mortality rates from March 2020 to June 2021 were, respectively, 6,407.9 and 179.3 per 100,000 inhabitants and the lethality was 43.3. Regarding the analysis of the daily trend of rates in the period from March 2020 to June 2021, both mortality and incidence increased. Conclusion: it was found that the behavior of the trend of rates in the first wave was increasing in the incidence of confirmed cases and the lethality decreasing, and in the second wave, the mortality and lethality rates were increasing.

Introduction: coronavirus 2019 Disease (COVID-19) was quickly declared a pandemic, and Brazil is facing the most significant health and hospital crisis in its history. From March to June 2021 represented 50.8% of all deaths in the State of Espirito Santo. Objective: to analyze the lethality and mortality by COVID-19 in the State of Espirito Santo from March 2020 to June 2021. Methods: an ecological study was carried out, using a time series of public and official data available on the Health Department of the State of Espirito Santo, Brazil. Were considered information about cases and deaths (from March 2020 to June 2021) of COVID-19. Percentage case-fatality and mortality and incidence rates per 100,000 population were calculated. Time-series analyses were performed using the Prais-Winsten regression model, estimating the Daily Percent Change (DPC), and the trends were classified as flat, increasing, or decreasing. Significant differences were considered when p<0.05. Results: 524,496 confirmed cases of COVID-19 as of June 30, 2021, and 11,516 progressed to death. The presence of cardiovascular diseases represents more than half of confirmed comorbidities (54.37%) in patients with COVID-19, followed by diabetes (19.95%) and obesity (9.34%). Men had higher mortality and lethality, especially in older age groups, but the incidence was higher among women. A characteristic profile of two waves was observed; the first wave was extended from March to October 2020 and the second complete wave from November 2020 to June 2021. During the second wave, high peaks of incidence, lethality, and mortality were recorded. At the end of the second wave, the incidence rate remained with increasing trends (p < 0.05), with a DPC of 2.06%. Conclusion: the peak concentration of cases, deaths, and indicators of lethality, mortality evidenced even after one year of pandemic, characterizes the severity of the COVID-19 pandemic, still in entire evolution in the State Espirito Santo and Brazil.
