Who says patient zero is not necessarily from Wuhan? What is the basis of this statement?

The WHO said that patient zero was not necessarily from Wuhan, but it was based on the fact that similar diseases occurred in other countries on 20 19, but at that time, it didn't explain what the reason was and there was no specific diagnosis, so it was dealt with under an unknown excuse, that's all, but it was impossible for us to go back to that time to deal with things. We don't know the exact cause at that time, so patient zero doesn't necessarily come from Wuhan, and we don't know much about it. We can only say that such things can be done slowly. Maybe not everything will have an answer, but we must try our best to find out.

In fact, there are many viruses in our life. Most viruses are in a state of peaceful coexistence for us, but if one day a virus that we don't know appears, it will really do us great harm.

For us, most people are afraid of viruses, because these seemingly insignificant lives will pose a great threat to our human body. Of course, in most cases, we may not get sick because of some viruses, but in some cases, some viruses can make us die.

Viruses coexist in our daily life. Our human body has a very powerful immune system, which can kill viruses that enter our body. But it doesn't rule out that some viruses are relatively new. We didn't have information about these viruses before, so there may be some complications, which will lead us to get sick. However, under normal circumstances, we are definitely immune to most viruses. Of course, the World Health Organization said that patient zero did not necessarily come from Wuhan, because there were such cases abroad before the outbreak of Wuhan.
