SARS-CoV-2 transmission dynamics in Belarus in 2020 revealed by genomic and incidence data analysis

Abstract: Background Non-pharmaceutical interventions (NPIs) have been implemented worldwide to curb COVID-19 spread. Belarus is a rare case of a country with a relatively modern healthcare system, where highly limited NPIs have been enacted. Thus, investigation of Belarusian COVID-19 dynamics is essential for the local and global assessment of the impact of NPI strategies. Methods We integrate genomic epidemiology and surveillance methods to investigate the… Show more

“…However, despite the prevalence of Omicron in New Zealand, we did not detect any infections originating from the community to the rest of the world (only from the community to the border). This contrasts with a recent study in Brazil which estimated around one export event to the rest of the world for every 10 introductions 36 , as well as studies performed in Colombia 14 , Jordan 33 , Rwanda 37 , Belarus 39 and Europe 40 . This discrepancy is perhaps due to the small population size of New Zealand at a global scale (five million people), and comparatively low global sequencing rates.…”

“…Therefore, this work fills this knowledge gap for Belarus by studying the excess overall mortality and related characteristics such as the related Google Trends search queries 28 during the epidemic period. This also complements the limited available knowledge about the Belarusian COVID-19 burden 25,29 . The limitations of such an excess mortality approach are that the exact (clinical) causes of each death are not reported for Belarus.…”

“…By integrating a phylogenetic and phylogeographic analyses to infer lineage importations with a longitudinal assessment of importation dynamics, we provide an analytical framework for exploring the connections between environmental factors, such as holiday and nonpharmaceutical intervention at a population level to lineage dissemination. The effectiveness measure that we introduce allows us to systematically compare and quantify links between NPis and importations [7,11]. Through the design of this effectiveness measure, which assesses temporally local changes in the decline of lineage importations, potential longer-term effects on lineage importations, such as a seasonality, do not affect the results.…”
