Maybe the ‘highly transmissible' is not applicable in hot weather.
A very good point. I am sure that there are others left wondering right now how you can have a person infected with the B117 variant, living in close contact with three others and who went on what can only be described as a comprehensive jaunt around a good portion of the Perth metropolitan area over a period of several days and did not pass the contagion on to another single person.
As I said yesterday. This is perverse.
