Your idea that the quarantine area isn’t large enough seems right. However, it seems to me that the idea that it can only be transmitted from contact with bodily fluids is blown away. Six days outside the host on a surface such as the ground sounds very long for a virus, doesn’t it?
“Six days outside the host on a surface such as the ground sounds very long for a virus, doesn’t it?”
Yeah, that’s why I don’t like the “it can only be transmitted by bodily fluid” statement. In 6 days the body that deposited it won’t be around and it won’t be fluid. If true surface contact transmission could be a nightmare in cities.
