Our study was focused on the relation between AIDS and opportunistic diseases. We aimed at obtaining a geometrical representation for those EU countries for which there was sufficient data. A linear representation was obtained, with Portugal at one extreme, followed by the south European countries and lastly the north and central European countries. This representation was validated through an "experiment" in which the population of Luxembourg was increased first 50 times and then 100 times.
