Makes it easier to track those with "questionable" tweets since they have to be live flagged in a DB somewhere.
Add to that, POTUS uses an iPhone. Are they now front-running his tweets. Is this part of the McChrystal Disinfo campaign?
Sounds like the bat virus was modified to allow host cell entry.
IOW, bat virus won't bind and enter into a cell easily, so that portion of the virus was replaced by one that attaches and enters easily. Modified.
Just my guess.
In the beginning there were rumors of lab techs selling test animals to the markets. So it could be test animals that were sold had the modified bat viruses that could enter human cells.
I think that's a red herring, though. I think the virus was distributed intentionally and was targeted. There may also be a known treatment/prophylactic given to the couriers.
