I saw this on Twitter and wondered - Given that ME may have environmental triggers has anyone mapped where people with ME lived when they started being ill ( i know that this will be difficult for gradual onset) My interest is piqued as most of the mums i know are either rural ( potential pesticides) or in old industrial heartlands. Does anyone feel this is worth an MEA survey?
If you mean the type of environment ( rural, semi-rural, urban industrial, city centre, suburban...) rather than actual geographical location, you could experiment to see how feasible it is by setting up a poll on this forum.
To be meaningful you would have to correct for population density, otherwise I just see it being a map of population density.
ME and CFS show up all over the world in similar prevalance, if there are any key environmental factors (besides infections), they seem ubiquitous.
We know that ME happens in epidemics and clusters and organophosphate poisoning in rural areas gives a syndrome similar to ME. Glandular fever is ubiquitous though most people never get ME from it. I don't think a map would tell us anything more.
Years ago, someone had an online map somewhere that people with ME/CFS could add themselves to. I don't remember who or where.
