Ya, that is noted in the post. Otherwise, it would be hard to imagine how HIV gene sequences would get in the mix. Unless perhaps there was a monkey involved...which seems less likely than this coming out of a lab
For an analogy, let's imagine that the genome of the virus were a short esay, and the whole genes were sentences. It is like claiming plagirism, because two persons use the word "banana" and the word "apple" in another sentence and then they used "co???ion" and "in???ing" in another two sentences.
COVID-19 is bonding to T-cells and killing them, in a way that is similar to HIV but not exactly the same
The important part is in Table 1. If you take a look at the coincidences, the first two are equal but very short. The third one has a hole and it has a few differences
