Are we dealing with a mutated strain of Covid-19?

#Malaysia has detected a mutated strain of the novel #coronavirus, called D614G, which is "10 times" more infectious, the country's Health Ministry Director-General said. The mutation is also the predominant one found in Europe and the US. pic.twitter.com/BeS4SHWezD

This makes too much sense.  I remember when this thing first started they talked about at least two strains of this thing and predicted that we would see many mutations.

Additionally if I remember correctly New York got hit with the "deadly" form of the disease while other countries were dealing with the minor form.

With this mutation we could be looking at round 2 (or is it 3) of this thing.

Question.  In an average year about 1/2 a million people die from medical mistakes.  Is it too much to ask just to swing the economy open full bore and to seek herd immunity?
