The answer to this is older, but it's not a proven fact even though schools teach it as if it were. It is still just a theory if you think about it with how much the earth moves, areas of rock could be complete upside down and no one would know, it would be like history in reverse.

aalyn [17]

Answer:

No

Explanation:

The short answer is no, but the more complex one is that it depends on the virus. In the case of *****-19, the answer is no, as many people have recovered from  it.
