21/04/20 16:20 from TWEETS BY MIKENOV from mikenova (1 sites) we provide direct evidence that the SARS-CoV-2 has acquired mutations capable of substantially changing its pathogenicity.

This graphic shows the deadly strain that hit Europe (in blue) and the mild strain that mostly hit the US such as Seattle (in orange) ________________________________________________________________ https://tweetsandnews.blogspot.com/2020/04/why-is-covid-19-mild-for-some-deadly.html ________________________________________________________________ Viral strain SARS-CoV-2, which causes COVID-19, is a single-stranded RNA virus that has the ability to mutate quickly. Over time, and as it spreads around the world, it will develop genetically distinct strains. Some of these strains may spread more easily, or cause more severe disease. However, to date there is no evidence that the SARS-CoV-2 viruses circulating now are clinically very different from each other or that their minor genetic differences explain the range of symptom severity patients are experiencing. ________________________________________________ M.N.: Hypothetically, if this virus was genetically manipula
