Why did an outbreak occur in Wuhan?

A reasonable explanation is that COVID-19 originated from the South China seafood market in Wuhan, and these viruses were spread from wild animals to humans. This explanation is very reasonable and accepted by many people, because SARS is like this. In 2003, SARS virus was found in civet cats, which proved that some people were infected by eating civet cats.

One of the turning points

It is the Korean epidemic that has become serious. Media reports in Japan and Taiwan Province Province pointed the source of the new coronavirus to the United States. Because the early Japanese COVID-19 patients had only been to Hawaii, they were diagnosed. Therefore, some people even suspected that there were COVID-19 patients among the flu patients in the United States at that time.

At that time, there was a critical article, that is, inferring the origin of COVID-19 through genetic testing technology. The results of this research report show that COVID-19 here belongs to grandchildren, while grandparents belong to the United States, and the COVID-19 virus in the United States has more kinds and is older.
