Weekly new cases per capita is merely a function of number of tests performed by authorities, and furthermore the false positive rate of those tests too. Percent positivity of those tests is a somewhat more accurate indication, but those figures rarely see headlines because they are less sensationalist. For example, UK test positivity rates are less than 1&amp;#x2F;10th what they were at the peak.</text><parent_chain><item><author>AlanSE</author><text>It&amp;#x27;s the same virus no matter where you are in the world.

We don&amp;#x27;t know that there&amp;#x27;s any difference, currently, between what variants are dominant in different parts of the world.  But, we sure don&amp;#x27;t know they&amp;#x27;re the same, either.</text><parent_chain><item><author>AlanSE</author><text>It&amp;#x27;s the same virus no matter where you are in the world.
