That is something all the Health Organizations are saying doesn't happen.
I suspect this virus always burned out in the jungle because folks died off pretty quickly and didn't travel much.
But turn it loose in a modern city/airports and all bets are off.
It DOES transmit quite easily and quickly. And the gestation period allows for wide dispersal.
CDC and WHO wouldn't lie to us, would they? lol
“Close proximity” is what is really scary.
Mass transit, schools, office buildings, even grocery stores. No way to do any of this with unknown carriers in and about these areas.
The idea of everyone sheltering in place for 30 days would totally stop it, but that idea is also totally unworkable.
