COVID is highly contagious. I don’t believe the new strains are any more contagious than the original.
Other than the media writing those words, their seems to be no clinical data to support a change in the level of contagiousness.
I have no knowledge of the UK’s study but how much more contagious can
it be ? Maybe it survives longer in the air or on surfaces. Maybe its halflife is extended. Maybe it can now penetrate the body through sores and abrasions, or through the ear canal. Until there is a study specifically saying HOW the references to this mutstion are somewhay meaningless.
