For more than a year, the coronavirus has been causing many problems on Earth, and there is still no clear explanation of the first case of coronary heart disease and even the date of the first outbreak. New research by researchers at the University of California shows that the uninvited guest has been working since September of last year, months before seeing the first outbreak in Wuhan, China.
Epidemiological research and simulations it shows It is likely that the corona virus first infected a person in early September of last year and has spread rapidly since then. Molecular simulations suggest that the virus was initially undetectable and could spread rapidly.
One of the questions that always occupies the minds of researchers is when did the corona virus come and how long can it survive?
To answer these questions, it is important to know how the virus spreads, the genetic diversity of the virus, and the first cases.
After identifying the first case of the coronavirus, Chinese authorities quickly took precautionary measures, and the lives of the Wuhan people went out of their way. As of April this year, quarantine conditions were tight, but the corona virus was able to spread to more than 100 other countries.
SARS-CoV-2 is said to be a common virus between humans and animals and is thought to have been transmitted from animal to human. So far, many attempts have been made to identify the first case of coronary heart disease in humans.
According to this study, the corona virus did not have much prevalence after its appearance in October to November 4th. 13 days later, the number of patients reached 4 and 9 people became ill by the 10th of Azar.
