Archeogenetics

Archeogenetics Archaeogenetics is a field of study that combines archaeology and genetics to investigate the evolutionary and demographic history of human populations.  Archeology Archaeology is the scientific study of human history and prehistory through the excavation and analysis of artifacts, structures, and other physical remains. It is a multi-disciplinary field, and archaeologists collaborate with specialists from many other areas, including geologists, biologists, climatologists, and historians, to build a comprehensive understanding of the past. Genetics Genetics is the study of heredity and variation in living organisms. It encompasses the fields of molecular biology, biochemistry, and statistics. It is concerned with the structure and function of genes, how genes are passed from one generation to the next, and how genetic variations lead to differences in traits and characteristics among individuals. Genetics plays a crucial role in many aspects of biology, from the regulati

Genomic Tracking of SARS-CoV-2 Variants in Myanmar

 In December 2019, the COVID-19 disease started in Wuhan, China. The WHO declared a pandemic on 12 March 2020, and the disease started in Myanmar on 23 March 2020. In December 2020, different variants were brought worldwide, threatening global health. To counter those threats, Myanmar started the COVID-19 variant surveillance program in late 2020. Whole genome sequencing was done six times between January 2021 and March 2022. Among them, 83 samples with a PCR threshold cycle of less than 25 were chosen. Then, we used MiSeq FGx for sequencing and Illumina DRAGEN COVIDSeq pipeline, command line interface, GISAID, and MEGA version 7 for data analysis. In January 2021, no variant was detected. The second run, during the rise of cases in June 2021, showed Alpha, Delta, and Kappa variants. The third and the fourth runs in August and December showed only a Delta variant. Omicron and Delta variants were detected during the fifth run in January 2022. The sixth run in March 2022 showed only Omic
