Study shows how D614G variant gains upper hand over original SARS-CoV-2 virus

Study shows how D614G variant gains upper hand over original SARS-CoV-2 virus Prior to the emergence of new mutants of the coronavirus, such as the British variant B.1.1.7, the SARS-CoV-2 variant named D614G had already mutated from the original SARS-CoV-2 pathogen that triggered the pandemic. D614G has rapidly spread to become the most abundant variant worldwide and this D614G mutation remains in all the new emerging variants. An international team including researchers from Bern has now been able to demonstrate in both the laboratory and in animal models why the D614G variant was able to gain the upper hand over the original SARS-CoV-2 virus.

WHO team in China: Searching for coronavirus′ birthplace | Science| In-depth reporting on science and technology | DW

What are zoonoses? One of those researchers, wildlife veterinarian and microbiologist Fabian Leendertz, who helped trace the initial Ebola infection back to bats that lived in a hollow tree where children played, joins the WHO team on its mission in China. Leendertz s research helped experts understand how the disease had spread and the risk posed by close contact with these animals.  While identifying that first case was important in curbing Ebola, the detective work was made much easier because of how lethal and unique Ebola is, says Martin Beer, a professor of virology at the Federal Research Institute for Animal Health in Germany.
