I forget who wrote an article on this situation but I read it a month or so ago. The hypothesis is this:
They will push the *idea* of the marburg virus to explain all the blood clots, heart issues and breathing problems (due to microscopic blood clotting) that people will experience from a) jabs, and b) the 5G effects (which will worsen the jab's effects).
The actual marburg virus, similar to ebola, is super contagious and deadly, but (like all very deadly diseases), it kills so fast that it does not spread far and wide because its hosts don't live long enough to spread it. That's the only advantage of super deadly diseases - they don't last long. The other thing will blood diseases is they can't be spread unless you come in contact with the blood. So even if one has the marburg virus and they are standing next to you, unless they bleed on you (or maybe saliva), you won't be infected (and even then, the blood/saliva would have to get in your mouth or in your body through a skin wound). The idea of a global marburg virus is impossible with human transmission. But people will believe it because it's on CNN...
