US, WASHINGTON (ORDO NEWS) — Scientists have found that coronavirus has existed for a long time, but it began to mutate relatively recently. The infection spreads at an incredible rate. Scientists from America and Australia said that the virus appeared much earlier than it was first detected in Wuhan.
Experts believe that the virus has existed for a long time, but it mutated only some time ago. Previously, it was transmitted to people only from animals and did not spread from person to person.
Scientists still had to admit that coronavirus can mutate. However, such mutations were not found in animals. Accordingly, a mutation began to appear only after the virus entered the human body.
The doctor Francis Collins says that mutations could last for a long period of time and as a result, the coronavirus was able to not only cause dangerous complications, but also be transmitted from person to person.
It is worth noting that today the number of infected people worldwide has exceeded the figure of 700 thousand people and continues to increase. Over the past week, most patients were recorded in the United States.
