Yes, I'm sure, and it's not just my opinion, but consensus. Autoimmunity was doubling every couple decades, but won't again 'cause more than half the population now has eczema. Diabetes had been doubling, too. Diabetes as a rare disease existed anciently (as did asthma, more commonly) but exploded in the nineteenth century, as did seasonal allergies, starting in the cities and only later smaller towns and rural areas, to the astonishment of doctors. It was unknown before, as was MS. (Temporary loss of sight can be caused by many things, including CCI or trauma.) Lupus goes back further. (One famous case "first case of MS" a few centuries earlier was thought to be MS, but is now thought to be lupus.) I don't know of any ancient identification of seasonal allergies, and the Razi Wikipedia page doesn't give one that. It wasn't common before the nineteenth century, according to nineteenth-century doctors who watched it balloon during their lifetimes. We also have (a diminishing number) of native populations to study and atopy is very rare, MS was unknown amongst them. Similarly diabetes. Etc. My sources aren't general but journal articles, those notes aren't easily available to me. I read at least the abstracts of getting on to 500,000 journal articles over about ten years and retain notes on 100,000 articles (not all the original journal articles.)
