Just to add to this, in the linked paper by Worobey et. al., Fig 2(B) shows something they label as "Centroid of Blue Cases". That centroid appears to be almost squarely on the location of the Wuhan Institute of Infectious Diseases.
For some reason, neither the locations of the Wuhan Institute of Infectious Diseases or the Wuhan Institute of Virology are mentioned in the linked paper.
- anigbrowl 4y agoThis is correct, but the paper does observe that these second-stage cases (mostly reported around January and February) occur in an area of high density housing with a preponderance of elderly people.
- AlanYx 4y agoAre you referring to the linked paper or something else? As far as I can tell (the writing style is not very clear IMHO), the Fig 2(B) blue cases are not second-stage cases, but rather a plot of "cases with no known link to the market". As for your second point, I don't see any discussion in the paper that this cluster "occur[s] in an area of high density housing with a preponderance of elderly people". Where are you seeing this?
- anigbrowl 4y agoOf course I'm referring to the linked paper. If you are not seeing such discussion perhaps you should read it more slowly. It's early in the Results section. The clustering of COVID-19 cases in December around the Huanan market (Fig. 1, B and C, insets) contrasts with the pattern of widely dispersed cases across Wuhan by early January through mid-February 2020 (Fig. 1, D and E), which we mapped using location data from individuals using a COVID-19 assistance app on Sina Weibo (26). Weibo-based data analyses show that, unlike early COVID-19 cases, by January and February many of the sick who sought help resided in highly populated areas of the city, and particularly in areas with a high density of older people (Fig. 1E and figs. S9 and S10).
- AlanYx 4y agoSorry, I'm not understanding how what you're quoting there relates to Fig. 2(B). That's a reference to a separate Weibo-based data analysis that has no link at all to Fig. 2(B).
- anigbrowl 4y agoIt's not my job to read the paper and look at the figures for you. Try putting the maps side by side and realizing they show the same geographic area. Fig 2B is an exemplar, as is clear from the description: 'Schematic showing how cases can be near to, but not centered on, a specific location.'
- AlanYx 4y agoI'm trying to be civil, but you keep making statements about the paper that are objectively not correct. Fig. 2(B) does not show "second stage cases (mostly reported around January and February)" as you posted earlier. The map from the Weibo analysis is not shown in the paper, so one can't "put[] the maps side by side". Moreover, it's irrelevant to claim that a Weibo analysis of second stage cases not shown in the paper is relevant to the interpretation of figures in the paper that are not limited to second stage cases.
- anigbrowl 4y agoPerhaps you should get someone else to explain it to you. You are complaining that the map from the Weibo analysis is not shown in the paper, but it is, in figures 1D & 1E. Either you have poor reading comprehension or you are just trying to confuse people.
