Just about to catch up with the thread, but 2 things occurred to me this morning about this "new strain".
Firstly if viruses mutate to adapt to their environment and survive (the reason they become less deadly), then could locking us all up for months with little or no contact cause this?
Secondly if this new strain is 70% more contagious☆ but can be controlled by the social distancing measures we've had all along then does that mean covid wasn't anywhere near as contagious as we told during the spring/summer this year?
☆note...no one has actually explained what 70% more contagious means yet....
