Actually we don’t know from the report that the bloke with the pressure washer didn’t pour bleach or some other strong chemical that would have had a virucidal effect on the vomit before using the pressure washer. I hope to God he did and waited long enough for it to take effect before proceeding.
As the dude’s shirt said, You only live once.
The EPA outlawed using bleach to clean public areas like parking lots as it's toxic to insects and plants, and could be washed into ground water. It's just way too dangerous to use.
They're in street clothes, their pants legs are soaked and there's no evidence of anything but a pressure washer connected to a water hose. Well, other than the Mt. Dew bottle sitting on the ground where it could get sprayed.
Those two were exposed to ebola if it survived in the vomit on the sidewalk, no way around it.
