Covid spread to entire world in just 1 month in Apr 2020…
Yet Delta has taken 16 months to do the same thing, despite being twice as communicable than that Apr 2020 variant. Hmm… Wow.
This tells me that the spread in April 2020 was observation effect.
Prior spread, 100%.
I'll modify this to 4 months vs. 14 months, just to ensure apples-to-apples… but the argument still stands. Add to this a 4 month spread during the most extreme mitigation measures.
