After originating in Wuhan, China in late 2019, the latest form of coronavirus, SARS-CoV-2, and its third pandemic of the last 17 years, has spread COVID-19 across the globe. Some countries claim fewer cases, like China, while some can't know figures, like Brazil, but one thing is clear; the half the world that interacts with China even indirectly has it, and it has mutated along the way. The California version which came from Asia is different than the New York version that came from Europe.
Fortunately, none of the mutations have increased transmissibility, according to
a new paper which looked at virus genomes from over 46,000 people with COVID-19 from 99 countries.
