You first start by devising an experiment that proves contagiousness, which is absolutely trivial and easy to do. You just start by recording the fact that the disease can be transmitted from person to person.

Are you aware that all such trivial and easy experiments during the Spanish flu and later during the polio epidemic failed? They had symptomatic patients in close contact and sneezing multiple times in healthy subjects' faces (who weren't exposed to the disease prior to that) and couldn't get a single person sick. They tried injecting them with mucous and even that failed. Those experiments proved said diseases are not contagious, meaning the contagious pathogen hypothesis goes down the drain. So what now?

From 1933 to present day, virologists have been unable to present any experimental study proving that influenza spreads through normal contact between people. All attempts were met with failure.
