As many as eight different strains of the coronavirus are currently navigating the globe, scientists say.
While similar in makeup, the various strains of the SARS-CoV-2 virus have mutated as it’s been passed from country-to-country, according to researchers. However, unlike most forms of evolution, health officials say the strains don’t appear to grow more deadly as they mutate. As a result, no strain is more lethal than the others, says Charles Chiu, a professor of medicine and infectious disease at the University of California.
While the discovery of eight different strains might not sound like good news, it has proven that quarantining people works in curbing the spread of the virus. Scientists say there were more than eight strains, but some have died off in areas that practiced shelter-in-place measures.
