He says the exact role of the market remains unknown.
There was spread among people who were [there] and lived and worked and visited the Huanan market throughout December. How it was introduced and spread within the market is still unknown. We have a map and have mapped over time the spread of the virus among the earlier cases that were linked to the market. We have a picture of where the cases worked in the market.
We have genetic sequences for some of these cases … All that tells us there was a spread among people in Huanan market in December rand therefore the market probably was a setting where that kind of spread could happen easily, but it’s not the whole story. We know there was also spread among individuals who were not linked to this market. They were linked to other market … So the picture is not clear in that respect.
We are still working with the hypothesis that it could have been introduced by a person who was infected and then spread to other persons in the market. But it could also be through the introduction of a product. Among the more interesting products were frozen farmed wild animals . Some of these species are known to be susceptible to these kinds of viruses.
The virus’s path from the animal to the Huanan market could have been very convoluted and could have crossed borders, Embarek adds.
