NCBI database and Covid-19

Recommended Posts

I read that on January 10, 2020,  after isolating the virus from patients, Chinese scientists posted its genetic sequence online .

But it was not listed on NCBI until 18-JUL-2020.
Severe acute respiratory syndrome coronavirus 2 isolate Wuhan-Hu-1, complete genome
https://www.ncbi.nlm.nih.gov/nuccore/1798174254

Why did it take so long to post in NCBI?
Where did the Chinese originally post it?

Also, is this the correct forum to post this kind of question?

Well, I am certain you are wrong. I have looked at the sequence days after it was published mid-January (well, and the rest of the community even earlier). I suspect you might have looked at the revision dates rather than the original posting date (I remember that there were a few bases being corrected after more sequencing, but I might be misremembering). 

There are also many more sequences out there and perhaps updates to RefSeqs. But either way, your premise is clearly wrong.

Edit: I quickly checked the entry: the date in the header of Genbank entries signifies the date of last modification, not the date of submission and I think that is what you looked at. It is the right sequence, though, but you can look at the history and see where it was originally posted. IIRC it was originally submitted early January and I think it was available about a week after.

Double edit: apparently lack of sleep significantly reduces my already poor spelling abilities. I should call it a day at some point.

Yes, great, thanks. I found the original.
Wuhan seafood market pneumonia virus isolate Wuhan-Hu-1, complete genome
https://www.ncbi.nlm.nih.gov/nuccore/NC_045512.1    (13-JAN-2020)

I have 2 more questions: 
1) You say "can look at the history and see where it was originally posted."
Do you mean the seafood link above or the original Chinese post?
2) Where/how can I find the link for the new UK variant?

If you go through the headers there is a line somewhere indicating the original submission, as well as another line stating whether the sequence has been updated at some point.

If you are interested about variants, I think the GISAID database is more helpful (https://www.gisaid.org/).
