Angular could be another way to describe it, indeed lol.
Concerning the article: It would be nice to know whether this age- and gender-related pattern also occurred in the other outbreaks.
I tried to look for more info on this but found very little, the sources from the rest of Europe mostly described the symptoms, and focused little on the epidemiology, though I did notice that in other countries it spread through a larger number of cities than in England, and in less industrialised ones, so it's safe to assume that the age and gender-related spread pattern probably was the same, but it most likely did not affect the higher class as much.
That does put a tiny dent in the hantavirus theory as an explanation for the outbreaks, but hey, maybe mice were less picky and/or more numerous in mainland Europe.
