Article Synopsis
- Asymptomatic individuals contribute significantly to COVID-19 transmission, prompting this study to investigate the prevalence and factors affecting transmission in Araguaína, Amazon.
- The research, conducted in February 2021, found an active infection rate of 6.2% and a prevalence of 13.5% among a statistically representative sample of 497 participants, with notable under-reporting of cases.
- Results indicated that working from home reduced infection risk and specific symptoms were correlated with positive tests, emphasizing the need for enhanced vaccination strategies and effective management tools to curb COVID-19 spread in the region.
Tocantins is a state in the cross-section between the Central-West, North and Northeast regions of Brazilian territory; it is a gathering point for travelers and transportation from the whole country. In this study, 9493 genome sequences, including 241 local SARS-CoV-2 samples (collected from 21 December 2020, to 16 December 2021, and sequenced in the MinION platform) were analyzed with the following aims: (i) identify the relative prevalence of SARS-CoV-2 lineages in the state of Tocantins; (ii) analyze them phylogenetically against global SARS-CoV-2 sequences; and (iii) hypothesize the viral dispersal routes of the two most abundant lineages found in our study using phylogenetic and phylogeographic approaches. The performed analysis demonstrated that the majority of the strains sequenced during the period belong to the Gamma P.

Countries with inadequate infrastructure experience difficulties in expanding their qPCR testing capacity.
