You do know that hackers can put information in too?
In reality it dosen't matter where the coronavirus came from. Its how we deal with it.
Imagine that you can touch something invisible to your senses and die from it.... gives you a new point to ponder in life.
Think about why there are emergency measures/procedures to follow. Its all mostly based on past experiences and how to do procedures better.
Lessons will be learned from all of this; and procedures made to cope with future outbreaks.
Like anything else people will forget in time.... their procedures will become lax.... some time passes, and boom it happens again.....
