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

Learners studying English for Specific Purposes (ESP) at University regard writing academic papers as a complex process since they have to consider issues about academic writing conventions as well as ethics. This current research examines university students' perceptions of ESP academic writing within the context of the online learning which emerged due to Covid-19 and, therefore, through the Information and Communication Technologies (ICT) and, particularly, utilizing the Flipped Learning approach as an active learning strategy to enhance ESP academic written competence. To be more specific, we examined how students, in tertiary education, perceived ESP academic writing skills within the field of Business English. The participants are 28 students doing the Degree in Administration and Business Management in a Spanish polytechnic. A mixed method research has been conducted for this current paper since both quantitative as well as qualitative methods were utilized for data collection. Regarding this study, both a questionnaire and a focus group interview were utilized to analyse the data. The outcomes proved that students' perceptions towards academic ESP written competence, using Business English, within the Flipped Learning approach was positive. The major results showed students' awareness of their needs and ESP written requirements. This research concludes with some future research suggestions.

ABSTRACT

With the first confirmed cases of COVID-19 in March 2020, a long and strict lockdown was implemented in Argentina, as a means of avoiding health services collapse. Measures were taken early in order to strengthen the health system before the potential spread of the virus. Mandatory isolation measures impacted on the energy system: they modified energy demand and production patterns, and caused reasons for uncertainty among investors and project stakeholders. Nevertheless, profound changes caused by the pandemic, pave the way for the adoption of sustainable solutions with the potential to improve people's quality of life. This paper aims to explore the effects of the COVID-19 lockdown on the Argentinian energy sector and on the course of the transition. By means of secondary sources, such as public reports and national statistics, and semi-structured interviews, changes in the energy sector are analysed as well as local-scale alternatives for the post-pandemic. Community-led energy initiatives and the possibility of implementing sustainable practices, could contribute to reducing uncertainty and valorizing local resources and capabilities.
