YouTuber Tim Truth was the first to compile an in-depth video of the incoming video evidence from all around the world. He has a decent track record with objective reporting and couldn't ignore the creepy facts.
The seemingly synthetic worms react to heat and water (more precisely, pH is coined).
Water or moist activates them as we can see how one worm absorbs water and starts moving afterwards (at 2m00s).
The micro worms resemble the phenomenon of Morgellon fibers found in patients suffering from Morgellons disease. Independent scientists studied the fibers more than a decade ago. The micro worms in the masks seem to be Morgellons 2.0.
A hypothesis. The worms are micro robots for tagging and tracing humans or other purposes.
Hot breath lures them out of the textile until they "stand up" facing the source of warmth.
Then, on inhaling, they go airborne and travel up the nose or nose cavity. Perhaps they are programmed to migrate to the brain.
