Overview of the SARS-CoV-2 genotypes circulating in Latin America during 2021 (preprint)

Latin America is one of the regions in which the COVID-19 pandemic has had a stronger impact, with more than 72 million reported infections and 1.6 million deaths until June 2022. Since this region is ecologically diverse and is affected by enormous social inequalities, efforts to identify genomic patterns of the circulating SARS-CoV-2 genotypes are necessary for the suitable management of the pandemic. To contribute to the genomic surveillance of the SARS-CoV-2 in Latin America, we extended the number of SARS-CoV-2 genomes available from the region by sequencing and analyzing the viral genome from COVID-19 patients from seven countries (Argentina, Brazil, Costa Rica, Colombia, Mexico, Bolivia and Peru). Subsequently, we analyzed the genomes circulating mainly during 2021 including records from GISAID database from Latin America. A total of 1534 genome sequences were generated from seven countries, demonstrating the laboratory and bioinformatics capabilities for genomic surveillance of pathogens that have been developed locally. For Latin America, patterns regarding several variants associated with multiple re-introductions, a relatively low percentage of sequenced samples, as well as an increment in the mutation frequency since the beginning of the pandemic, are in line with worldwide data. Besides, some variants of concern (VOC) and variants of interest (VOI) such as Gamma, Mu and Lambda, and at least 83 other lineages have predominated locally with a country-specific enrichments. This work has contributed to the understanding of the dynamics of the pandemic in Latin America as part of the local and international efforts to achieve timely genomic surveillance of SARS-CoV-2.

Strengthening mental health responses to COVID-19 in the Americas: A health policy analysis and recommendations.

The COVID-19 pandemic is having a major impact on the mental health of populations in the Americas. Studies show high rates of depression and anxiety, among other psychological symptoms, particularly among women, young people, those with pre-existing mental health conditions, health workers, and persons living in vulnerable conditions. Mental health systems and services have also been severely disrupted. A lack of financial and human resource investments in mental health services, limited implementation of the decentralized community-based care approach and policies to address the mental health gap prior to the pandemic, have all contributed to the current crisis. Countries must urgently strengthen their mental health responses to COVID-19 by taking actions to scale up mental health and psychosocial support services for all, reach marginalized and at-risk populations, and build back better mental health systems and services for the future.
