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

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.

The Prevalence and Genetic Characterization of Strains of Isolated from Tick Vectors in Belarus (2012-2019).

sensu lato (s.l.) is the most common pathogen of medical significance transmitted by ticks of the family Ixodidae in Belarus.

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

Since the emergence of COVID-19, a series of non-pharmaceutical interventions (NPIs) has been implemented by governments and public health authorities world-wide to control and curb the ongoing pandemic spread. From that perspective, Belarus is one of a few countries with a relatively modern healthcare system, where much narrower NPIs have been put in place. Given the uniqueness of this Belarusian experience, the understanding its COVID-19 epidemiological dynamics is essential not only for the local assessment, but also for a better insight into the impact of different NPI strategies globally.

The Prevalence of Different Human Pathogenic Microorganisms Transmitted by Tick Vectors in Belarus.

Pathogens transmitted by ticks cause several important diseases in humans, including Lyme disease, the incidence of which has been increasing in Belarus. Between April and October 2017, a total of 504 questing Ixodid ticks (77% and 23% ) were collected from six regions and city of Minsk, in Belarus. All ticks were analyzed by RT-PCR amplification for the presence of , tick-borne encephalitis virus (TBEV), , and .

[Detection and antigenic characteristics of the recombinant nucleocapsid proteins of Lassa and Marburg viruses].

Two plasmid vectors, which allow the recombinant polypeptides of Lassa and Marburg viruses to be expressed in prokaryotic cells E. coli strain BL21 (DE3), were produced. The two recombinant polypeptides are able to bind specific antibodies.
