ABSTRACT

Objective: To analyze the impacts of the COVID-19 pandemic on Brazilian nurses' life, health and work. Methods: This is research with a qualitative and social-historical approach, guided by the New History framework. The study had 22 participants, with a prevalence of females. Data collection took place in December 2020, through semi-structured interviews, in a virtual environment, using an electronic instrument created in Google Forms and processed via email. The analysis was conducted using the oral history methodology, with data transcription, transcreation and categorization. Results: The pandemic had an impact on the personal, professional and educational dimensions of nurses. In the personal dimension, there were changes in the routine of life, fear of contamination, physical and mental exhaustion. In professional assistance, there was a work overload, shortage of personnel and material, a high number of contaminations and deaths of team members due to COVID-19. In professional training, adaptations to remote learning were necessary. Given the uniqueness and lethality of coronavirus, specialized nursing knowledge was essential in promoting confidence in the reception and care of patients in the community. Conclusion: The study valued Brazilian nurses' narratives about coping with the COVID-19 pandemic and expanded the discussion on labor deficiencies experienced by nurses and their aggravation in the pandemic context. The situation presented is worrisome and demands a critical look from those involved in the health and human care management process, aiming at adequate and safe working conditions for nursing professionals, with protection of workers' health and life.

ABSTRACT

The emergence and global dissemination of Severe Acute Respiratory Syndrome virus 2 (SARS-CoV-2) variants of concern (VOCs) have been described as the main factor driving the Coronavirus Disease 2019 pandemic. In Brazil, the Gamma variant dominated the epidemiological scenario during the first period of 2021. Many Brazilian regions detected the Delta variant after its first description and documented its spread. To monitor the introduction and spread of VOC Delta, we performed Polymerase Chain Reaction (PCR) genotyping and genome sequencing in ten regional sentinel units from June to October 2021 in the State of Minas Gerais (MG). We documented the introduction and spread of Delta, comprising 70 per cent of the cases 8 weeks later. Comparing the viral loads of the Gamma and Delta dominance periods, we provide additional evidence that the latter is more transmissible. The spread and dominance of Delta did not culminate in the increase in cases and deaths, suggesting that the vaccination may have restrained the epidemic growth. Analysis of 224 novel Delta genomes revealed that Rio de Janeiro state was the primary source for disseminating this variant in the state of MG. We present the establishment of Delta, providing evidence of its enhanced transmissibility and showing that this variant shift did not aggravate the epidemiological scenario in a high immunity setting.

ABSTRACT

The high numbers of COVID-19 cases and deaths in Brazil have made Latin America an epicentre of the pandemic. SARS-CoV-2 established sustained transmission in Brazil early in the pandemic, but important gaps remain in our understanding of virus transmission dynamics at a national scale. We use 17,135 near-complete genomes sampled from 27 Brazilian states and bordering country Paraguay. From March to November 2020, we detected co-circulation of multiple viral lineages that were linked to multiple importations (predominantly from Europe). After November 2020, we detected large, local transmission clusters within the country. In the absence of effective restriction measures, the epidemic progressed, and in January 2021 there was emergence and onward spread, both within and abroad, of variants of concern and variants under monitoring, including Gamma (P.1) and Zeta (P.2). We also characterized a genomic overview of the epidemic in Paraguay and detected evidence of importation of SARS-CoV-2 ancestor lineages and variants of concern from Brazil. Our findings show that genomic surveillance in Brazil enabled assessment of the real-time spread of emerging SARS-CoV-2 variants.

ABSTRACT

Brazil has experienced some of the highest numbers of COVID-19 cases and deaths globally and from May 2021 made Latin America a pandemic epicenter. Although SARS-CoV-2 established sustained transmission in Brazil early in the pandemic, important gaps remain in our understanding of virus transmission dynamics at the national scale. Here, we describe the genomic epidemiology of SARS-CoV-2 using near-full genomes sampled from 27 Brazilian states and a bordering country - Paraguay. We show that the early stage of the pandemic in Brazil was characterised by the co-circulation of multiple viral lineages, linked to multiple importations predominantly from Europe, and subsequently characterized by large local transmission clusters. As the epidemic progressed under an absence of effective restriction measures, there was a local emergence and onward international spread of Variants of Concern (VOC) and Variants Under Monitoring (VUM), including Gamma (P.1) and Zeta (P.2). In addition, we provide a preliminary genomic overview of the epidemic in Paraguay, showing evidence of importation from Brazil. These data reinforce the usefulness and need for the implementation of widespread genomic surveillance in South America as a toolkit for pandemic monitoring that provides a means to follow the real-time spread of emerging SARS-CoV-2 variants with possible implications for public health and immunization strategies.

ABSTRACT

This article aimed to discuss the emblem of remote emergency education, understanding the challenges and potentialities of its inclusion in the school processes of the Brazilian basic education network during the Covid-19 pandemic, from journalistic and documentary material, from march to october 2020. Methodologically, we adopted exploratory qualitative research. The constituent method is documentary analysis from the perspective of categorical analysis. A database was built divided in two axes: a) Documents from normative institutions and b) Journalistic materials of public information available on the internet. The treatment of contents was analyzed by Atlas Ti software version 8.4.2. The results show the different contributions and functional operations of Distance Education and Emergency Remote Learning during the pandemic. It is perceived in the country that the impacts of implementing Emergency Remote Education in different school contexts reveal contradictions and vulnerabilities of access and technological education.
