He's jumping the gun - again. I see no suggestion of 'strong support' H-H transmission. Were that the case, we'd be several transmission generations down the road at this stage with more confirmed cases. Granted, lab testing/reporting time is always slower than anyone would like & if anyone contracted this novel strain without feelng a need to seek medical attention, a lot of potential cases are being missed.
That being said, I often wonder how many novel strains enjoy a quick run with mild illness, then peter out. Impossible to tell.
If you're in your head, you're behind enemy lines.
