I read that for some viral infections, it took multiple years to find the original source, while in other cases they found the source within months.

You read that? Or did you just think you did? Where is your source?
Perhaps you need to read a bit more.
For many viruses the source still has never been conclusively identified.
"Once pathogens start to spread by human-to-human transmission, the tracks leading back to the initial animal source grow faint and become nearly impossible to follow."
"Thus, animal sources for viruses that cause pandemics often remain shrouded in mystery. For some viruses, animal sources have been implicated after years or decades of large-scale international investigations. For other viruses, animal sources are highly suspected, but enough evidence has yet to be produced to pinpoint an exact species or range of species."
It would still be there in those wild animal populations, or antibody evidence that it was once there. So it's a matter of time.
"At best, this type of evidence is nondefinitive"and at worst, it leads us in the wrong direction in the hunt. Antibody responses to viruses are notoriously cross-reactive: the serological assays will react in the same way to related viruses, both known and as yet unrecognized. "
Read just a bit more and you will see the article is correct. The source may never be found. Especially without China's cooperation.
