New coronavirus revelation changes what we know about the outbreak’s origins

• A recent study that analyzed thousands of genetic sequences of the novel coronavirus concluded the pathogen may have jumped from animals to humans as early as October 2019.
• One report says the first COVID-19 case in China may have been discovered as early as November 17th.
• Separate discoveries from Italy, France, and the US all suggest COVID-19 was spreading weeks or even months earlier than was initially believed.

A peer-reviewed study looking at the genetics of the novel coronavirus published earlier this week said the virus has been spreading worldwide since late December, which would be much earlier than initially believed. However, the virus hasn’t circulated long enough to infect a significant amount of the population, which would get communities closer to acquiring herd immunity. The concept refers to having enough people in a community develop immunity to a pathogen via infection or vaccine so that outbreaks aren’t possible.

The study supports separate discoveries that say COVID-19 was spreading in several countries in Europe and in the US well before the first official cases were documented. More interestingly, it offers a timeframe for the virus’s jump to humans, saying SARS-CoV-2 could have infected the first people as early as October 2019.
