Seven facts about the origin of the new coronavirus

Despite the vast amount of research on the new coronavirus known as SARS-CoV-2, little is known about its origin. Indeed, the source of the virus is hotly debated, some theories indicate natural origin, and others claim that the virus was accidentally leaked from the laboratory.

Here’s what we know about the origin of SARS-CoV-2:

The virus was first reported in Wuhan, China.

In late December 2019, health officials issued the first warning about a pneumonia outbreak in Wuhan, China. These cases turn out to be the first reported cases of COVID-19 in the world. By early January 2020, researchers had identified a new coronavirus behind the case. Live science previously reported.. The virus was then officially named SARS-CoV-2.

It is closely related to the bat coronavirus, but the source of the animal is unknown.

The closest known one associated with SARS-CoV-2 is the coronavirus first identified in the horseshoe-shaped bat in Yunnan, China in 2013. Known as RaTG13, the virus shares 96% of its genome with SARS-CoV-2. However, RaTG13 has a specific sequence, and it was not possible to jump directly from bats to humans.
