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

What became serious was the Korean epidemic. Japanese and Taiwan Province media reports pointed out that COVID-19 virus originated in the United States. Because the early Japanese COVID-19 patients only went to Hawaii, the result was diagnosed. Therefore, some people even suspected that there were some COVID-19 patients among the American flu patients at that time.

At that time, there was another 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 COVID-19 virus in the United States has more kinds and is older.
