For contagious viruses?
Has there ever been a study that proves person-to-person transmission of viruses?
In the entire history of the published medical research, there is not one so-called pathogenic disease-causing virus that has ever been found in one bodily fluid of one person. Not HIV, Ebola, Zika and SARS-CoV-2. Do you disagree with that? Present a paper proving such and explain the process fully. You’d be the first in all of mankind to do so.

WHO is not a source. Never was and never will be. They are repeatedly exposed swindlers and you gonna fuck yourself out if you even try to pose that bastards as some kind of source.
For current topic source is a successfully replicated by several independent researches scientific paper with a complete description of a process of direct detection of presumable pathogen in human body fluids.
There are no any papers that describe direct detection of a virus in human body fluids. Everything we have is something with very questionable intermediate steps of "replicating" presumable virus in test-tube, when a body fluid first added to live cells in deadly solution, and when cells die for any reason, the soup from their remnants studied for virus presence, and not a body fluid, or using PCR "tests" that by definition can't be used to detect anything, because PCR is manufacturing technology and not a detecting technology. PCR process give correct and intended result only if you unambiguously provide a sample to replicate. In any other case, including the case when you are not shure if such sample present, PCR result is completely undefined and in no case could be used for anything at all.
