With thousands of people travelling between China and the United States, there is no real way to prevent exposure. If this virus were to actually mutate and become more virulent and communicable, almost nothing can be done to prevent a catastrophe.
My understanding, as of yesterday, the notification is that it is already mutating
as per the Chinese official coordinating study of the virus.
The problem with viri is that they mutate easily,
in that they have RNA, and lack DNA.
So, in their development, there is less genetic changing necessary in order to mutate.
Therein lies the problem with virus , they change and mutate rapidly,
thereby frustrating pharmacology .
