Sounds like the old assumptions about transmission and safety need a little revision, or two.
If you can catch it from a taxi ride, then the old “very close and personal contact” rubric is not operable.
Well, I am thinking that they mean someone getting into one of these taxis and sitting where an infected person has been is going to be touching surfaces where that person many have left sweat or blood or the products of a cough or a sneeze.
