I suspect there's something about viruses "they" are keeping hidden, something about the mechanics of how they work. I think they've indoctrinated the masses with false concepts of how it works. Chicken pox, herpes, warts, influenza and the like are definitely a thing that's contagious and are diseases not from microbes like bacteria, fungi, etc...
It looks to me like virus particles are produced by shredded cellular debris, they're not an independent entity at all. This idea that virus are like miniature microbes is fallacious, a natural/normal cellular mechanism (kept somewhat hushed up) is being hijacked.
I think once the viral process is understood it becomes a problem for the vaccine industry and their claims. So we've got a trillion dollar industry fighting on the side of some kind of weapon to keep everybody in the dark, keep them from ever having the knowledge to fight back.
Cellular debris is a secondary effect from a more primary cause such as chemical exposure and destructive energetic/electromagnetic sources (5G, HAARP, Monsanto-Bayer, chemtrails, smog). These weapons they make, I think they work as "combo" hits with the truth being the first hit. The Kung Flu, is probably the most scientifically accurate label so-far.
