“…Other researchers demonstrated that the studied health indicators presented similar serial correlation parameters in other Brazilian states 15,16 . Some years of mortality, lethality and incidence indicators did not show statistical significance during the analysis of the temporal trend, however the values presented are important for planning at the state level to propose measures to reduce or stabilize the number of cases and deaths.…”

Introduction: the progression of SARS-CoV-2 highlighted the Americas region for the number of COVID-19 cases and deaths. In Brazil, the Southeast region was one of the most affected, especially the state of Rio de Janeiro, due to its cosmopolitan characteristics. Objective: to analyze temporal variations in the incidence, mortality and lethality of COVID-19 in the state of Rio de Janeiro from January 2020 to December 2022. Methods: ecological time-series study with publicly available data on COVID-19 cases and deaths. Crude incidence, mortality, and fatality rates, and estimates of percent daily change (DPC) were analyzed using Prais-Winsten linear regression. With calculation of crude rates were performed using Microsoft Excel 2019, and DPC estimates were performed using STATA MP 17.0 software. Results: 2.5 million cases and 76 thousand COVID-19 deaths were confirmed in the state of Rio de Janeiro from 2020 to 2022, with lethality declining from 4.89% to 0.60%. The highest lethality occurred in May 2020 (11.59%), October 2021 (9.13%) and March 2022 (6.78%), showing a stationary trend. In 2020, incidence and mortality rates peaked in December (797.76 per 100,000 inhabitants) and May (43.96 per 100,000 inhabitants), respectively, followed by subsequent declines. Incidence trend was increasing in 2020 and stationary in 2022, while mortality decreased in 2021 and 2022 after stability in 2020. Conclusion: The incidence of COVID-19 peaked in 2020 and subsequently declined, suggesting partial transmission control. Mortality stabilized after 2020, indicating evolution in health care. Lethality showed a stationary trend, indicating an improvement in hospital capacity. The divergent behavior of the epidemiological indicators reflected the complex dynamics of the pandemic in the analyzed state. There were 790 thousand deaths from COVID-19 in the State of Rio de Janeiro in the period from 2020 to 2022.

“…An uncontrolled dissemination is observed, a behavior that was related to the pandemic response model 18 . And it can be justified by access to health care, socioeconomic and demographic conditions, and factors intrinsic to the population, such as age, lifestyle, comorbidities, among others 15 .…”

“…The state of Acre presents a complex scenario influenced by multiple variables affecting the pandemic and the spread of COVID-19 [ 7 , 50 ], leading to numerous challenges impacting incidence, mortality, and lethality rates. Among its 22 municipalities, 14 are categorized as rural [ 11 ], where rivers serve as crucial transportation routes for people and goods, and in some areas, they represent the only form of access.…”

The north region of Brazil is characterized by significant vulnerabilities, notably surpassing national poverty indicators. These disparities exacerbated the impact of respiratory illnesses on the healthcare system during the COVID-19 pandemic, particularly in areas with limited healthcare resources, inadequate infrastructure, and barriers to healthcare access. The crisis was further influenced by multiple lineages that emerged as significant virus variants associated with increased transmissibility. Within this context, our ecological study focused on analyzing the epidemiological evolution of COVID-19 in the state of Acre. We constructed time-series trends in incidence, lethality, and mortality from March 2020 to December 2022 using the Prais–Winsten regression model. Our findings revealed that in 2020, there was an increasing trend in incidence, while mortality and lethality continued to decrease (p < 0.05). In the following year, both incidence and mortality decreased, while lethality increased at a rate of 1.02% per day. By the end of 2022, trends remained stationary across all rates. These results underscore the importance of ongoing surveillance and adaptive public health measures to bolster the resilience of healthcare systems in remote and vulnerable regions. Indeed, continuous monitoring of the most predominant SARS-CoV-2 lineages and their dynamics is imperative. Such proactive actions are essential for addressing emerging challenges and ensuring effective responses to adverse situations.

“…The seven states in the North region collectively accounted for 11.9% of the country's total COVID-19 cases. Among these, the municipalities with the highest number of new cases were Manaus/AM (2,026), Belém/PA (1,686), and Boa Vista/RR (1,328). In July 2020, Pará held the fourth position with one of the highest COVID-19 case counts nationally.…”

Introduction: COVID-19 unfolded differently in Pará and Rio Grande do Sul, Brazil, owing to distinct socioeconomic contexts. From 2020 to 2022, both states implemented diverse measures against the virus SARS-CoV-2, including vaccination and variant monitoring, tailored to their specific challenges. Understanding regional impacts on COVID-19 indicators is crucial for designing effective control strategies. Objective: to analyze the incidence, mortality, and lethality of COVID-19 in Pará and Rio Grande do Sul and the trends of these indicators from 2020 to 2022. Methods: ecological study with time series from public and official data available in the Health Secretariat of Pará and Rio Grande do Sul, including all cases and deaths by COVID-19 from February 2020 to December 2022. Lethality, mortality, and incidence rates were calculated. Prais-Winsten regression analysis was used, and trends were classified as stationary, increasing, or decreasing. Significant differences were considered when the p-value is <0.05. Results: when examining the lethality rates between the states of Para and Rio Grande do Sul, an observable trend emerged during the analyzed period. It became evident that the total lethality rate consistently remained higher in Para. Noteworthy peaks in lethality were mainly observed during the months of April 2020, May 2020, and March 2021. The incidence rates showed increasing trends during 2020, both in Pará with a daily percentage change (DPC) of 1.69% (p <0.05) and in Rio Grande do Sul with a DPC of 1.70% (p<0.05). In 2021, the incidence was decreasing (p <0.05) in both states, with a DPC of 0.60% in Pará and 0.64% in Rio Grande do Sul and continued this trend in Pará in 2022 (DPC of -0.50% p <0.05), becoming stationary in Rio Grande do Sul, with a non-significant p-value (p> 0.05). Conclusion: the positive impact of the vaccination program is reflected in the evolution of the pandemic. During the study period Rio Grande do Sul and Para exhibited a stationary incidence trend, emphasizing the need for continued monitoring of cases and morbidity across various age and demographic groups.
