Abstract
A year after the World Health Organisation (WHO) declared COVID-19 as a pandemic, much has been learned regarding SARS-CoV-2 epidemiology, vaccine production, and disease treatment. Whole-genome sequencing (WGS) has played a significant role in contributing to our understanding of the epidemiology and biology of this virus. In this paper, we investigate the use of SARS-CoV-2 WGS in Southeast and East Asia and the impact of technological development, access to resources, and demography of individual countries on its uptake. Using Oxford Nanopore Technology (ONT), Nottingham-Indonesia Collaboration for Clinical Research and Training (NICCRAT) initiative has facilitated collaboration between the University of Nottingham and a team in Research Centre for Biotechnology, Indonesian Institute of Sciences (Lembaga Ilmu Pengetahuan Indonesia/LIPI) to carry out a small number of SARS-CoV-2 WGS in Indonesia. The ONT offers sequencing advantages that fit within the Indonesian context. Analyses of SARS-CoV-2 genomes deposited on GISAID from Southeast and East Asian countries reveal the importance of collecting clinical and demographic metadata and the importance of open access and data sharing. Lineage and phylogenetic analyses per 1 June 2021 found that: 1) B.1.466.2 variants were the most predominant in Indonesia, with mutations in the spike protein including D614G at 100%, N439K at 99.1%, and P681R at 69.7% frequency, 2) The variants of concern (VoCs) B.1.1.7 (Alpha), B.1.351 (Beta), and B.1.617.2 (Delta) were first detected in Indonesia in January 2021, 3) B.1.470 was first detected in Indonesia and spread to the neighbouring regions, and 4) The highest rate of virus transmissions between Indonesia and the rest of the world appears to be through interactions with Singapore and Japan, two neighbouring countries with a high degree of access and travels to and from Indonesia.Keywords
