There are 2 comments on BU Updates COVID-19 Dashboard Based on Total People Tested

  1. Glad that this is finally starting to be presented in terms of numbers of unique individuals rather than only in terms of numbers of tests. However, could we PLEASE see the raw numbers for totals of (1) unique individuals tested and (2) unique individuals who have tested positive — both for the last 7 days and CUMULATIVELY?

  2. The cumulative data from July 27 is still not displayed with the right denominator! That is where the data most needs to be displayed in this way, as I previously explained on my blog. The percentage of positive tests there should keep going up (as the number of people tested stays roughly constant while the number of positive results steadily increases), but instead it misleadingly keeps going down (as many people get negative results again and again).

    Using the number of people tested this week, according to the data provided, I calculate that the positive rate for people tested since July 27 is 0.58% (rather than 0.08%). That would mean that 1 in every 172 people in the BU community has tested positive since July 27. No doubt 0.58% is a little too high because some people got tested in previous weeks but didn’t get tested during the last week. Suppose the correct number is 0.4%. That would still mean the 0.08% presently displayed is out by a factor of 5!
