“That’s a big number, 13, with no link.”
But twice as many cases (28) in the initial group are linked to the market.

Also "no epidemiological link was found between the first patient [on Dec. 1] and later cases." https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30183-5/fulltext#seccestitle170 … Also, the next group pops up the following week (Dec. 10) and involves the market, a pattern which continues until the market closes...pic.twitter.com/xPnAKzUQZj

Also the same analysis that says the most recent common ancestor of the new coronavirus was from early December 2019, also posits that the virus may have jumped from animals to humans multiple times http://virological.org/t/preliminary-phylogenetic-analysis-of-11-ncov2019-genomes-2020-01-19/329 …pic.twitter.com/H5kVcN7tz0

"The "small clusters" described would all be part of the same spillover event and so infected with similar CoV variants, not multiple independent zoonotic introductions". This is correct. We believe this is a plausible scenario - and one of the other three scenarios from article
