Mortalidade e letalidate da COVID-19 no Estado do Pará, Amazônia legal, Brasil

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.Introdução: o crescimento dos índices do coronavírus na região Norte evidencia as desigualdades sociais históricas da região e os problemas no acesso à cidadania. Objetivo: analisar a mortalidade e letalidade da COVID-19 no estado do Pará, Brasil. Método: trata-se de um estudo ecológico com delineamento de série temporal de dados secundários. Foram consideradas todos os casos registrados e óbitos notificados por COVID-19 no período de março de 2020 a junho de 2021, no estado do Pará, Brasil. Foi utilizado a taxa de incidência, mortalidade e letalidade. Estimou-se a variação percentual diário e seus respectivos intervalos de 95% de confiança. Resultado: o total de casos confirmados e óbitos por COVID-19 no estado do Pará foi de 552.937 e 15.469, respectivamente, no período de março de 2020 a junho de 2021. As taxas de incidência e mortalidade do período de março de 2020 a junho de 2021 foram, respectivamente, 6.407,9 e 179,3 por 100.000 habitantes e a letalidade foi 43,3. Com relação à análise de tendência diária das taxas no período de março de 2020 a junho de 2021 tanto a mortalidade quanto a incidência foram crescentes. Conclusão: constatou-se que o comportamento da tendência das taxas na primeira onda foi crescente na incidência de casos confirmados e a letalidade decrescente e, na segunda onda, as taxas de mortalidade e letalidade foram crescentes

Exposição ao nível de ruído da equipe do setor da merenda de uma escola estadual do Grande ABC / Exposure to the noise level of the teaching sector of the stunning school of Grande ABC

O ambiente escolar é pouco analisado sob o ponto de vista da Higiene Ocupacional. Nas escolas, o ruído ambiental está presente através de diversas formas, causando diversos danos. Dessa forma, estudos que busquem a promoção da saúde auditiva e a conscientização da comunidade escolar com relação ao ruído são fundamentais. O principal objetivo desse trabalho foi identificar se as funcionárias da área da merenda estavam expostas a uma dose de ruído acima do nível de ação e elucidar a qual dose elas estavam expostas. O estudo foi realizado em uma escola estadual de ensino fundamental e médio, no município de São Bernardo do Campo/ SP. Para a avaliação do nível de ruído utilizou- se o equipamento Extech modelo SL 355 devidamente calibrado, com faixa de medição entre 50 a 100 dBA modo SLOW e curva de ponderação A e fator de troca q=5. Os resultados apresentados no estudo mostram que as funcionárias da merenda estavam expostas a uma dose de ruído acima do nível de ação. Devido ao nível de ruído exposto, devem ser iniciadas ações preventivas de forma a minimizar a probabilidade do ruído ultrapassar o limite de exposição

Epidemiological perspective of the evolution of the COVID-19 pandemic in Amapá State, Northern Brazil

Introduction: COVID-19 impacted health systems worldwide; the virus quickly spread in Brazil, reaching its 27 Federative units peculiarly. The northern country region recorded the lowest number of cases and accumulated deaths from the disease. However, it is a region of sizeable territorial extension and low demographic density, marked by socioeconomic inequalities and vulnerable groups, such as indigenous tribes, riverine peoples, and quilombolas. Sociodemographic factors may contribute to the dissemination of the coronavirus in this territory; thus, studies are needed to analyze the epidemiological indicators related to the pandemic. Objective: to evaluate incidence, mortality, and case fatality of COVID-19 trends in the state of Amapá, Brazil, from March 2020 to April 2021. Methods: an ecological time-series study was conducted with publicly accessible data from the Health Department of the State of Amapá. Incidence and mortality rates per 100,000 inhabitants and percentage case fatality were calculated. Crude rates were calculated by municipalities, age, and sex, per month. The Prais-Winsten regression test was performed, and the trends of monthly rates were classified as increasing, decreasing, or flat. Results: during the study period, there were 99.936 cases and 1,468 deaths accumulated by COVID-19 in the State of Amapá, Brazil. Macapá and Santana’s cities, which have the highest demographic density and Human Development Index (HDI), had the highest number of cases and deaths. The most vulnerable population was elderly males aged 70 years or over; these individuals had the highest cumulative incidence, case fatality, and mortality rates. The second wave of the disease (October 2020 to April 2021) illustrated a more aggravating scenario, with increasing incidence and mortality rates. Conclusion: the COVID-19 pandemic in the state of Amapá, Brazil, is in increasing evolution, which illustrates that non-pharmacological prevention measures and acceleration of vaccination must be strengthened to avoid the development of future waves of the disease

Temporal analysis of COVID-19 epidemiological indicators in a low-income Brazilian context: a retrospective analysis in Paraiba State

Northeast Brazil is a region with great international tourist potential. Among the states that make up this region, Paraíba stands out due to the presence of vulnerable groups and factors that contribute to adverse outcomes of COVID-19. Therefore, the aim of this study was to analyze the epidemiological data on the incidence, mortality, and case fatality of COVID-19 in Paraíba. An ecological, population-based study was performed, with data extracted from the Brazilian Ministry of Health database. All cases and deaths from COVID-19 from March 2020 to December 2022 were included. The time series was built by applying the Prais–Winsten regression model, and the daily percent change was calculated to analyze the trends. The highest case fatality of the entire period was in April 2020 (7.8%), but in March 2021, the state broke the dismal record of 1248 deaths and the highest mortality rate (30.5 deaths per 100,000 inhabitants). Stationary mortality and case fatality were better in 2022; however, in February 2022, the mortality rate was at levels similar to the same month of the previous year. These results illustrate that COVID-19 is evolving and needs to be constantly monitored.</p
