Leprosy

 Before the Covid pandemic, people would often try to understand the horrors of the fourteenth-century Black Death by saying it must have been like AIDS.  Actually, no.  Even though AIDS has, over the last 35 years or so, killed a lot more people than have been killed (so far) by Covid, it's not particularly like the Black Death (on which see more here).

The actual Black Death (first outbreak in medieval Europe in 1347) was very infectious and transformed society abruptly, with people going from infection to death in a very short time, whereas AIDS is not very infectious, requiring contact of bodily fluids, and, now that the medical profession has worked out treatments, not a death sentence.  (Well, life is a death sentence, but we're not going into that right now.)

Actually the Black Death was more like Covid-19, in its abrupt appearance, rapid spread, and impact on all of society.  But we're not going to have a third of our population dead in a few years, as in the fourteenth century, and there actually are treatments and vaccines, which they did not have then.  (Note:  there were no "Black Death Deniers" in 1347.)

AIDS is more like leprosy, in that it infected a fairly small proportion of the population, and those infected were avoided both as (potential) spreaders of infection and as people considered morally as well as physically compromised.

But let's talk about leprosy itself.  The disease appears in the Bible, called "unclean" in the Old Testament.  In the New Testament Jesus cleansed lepers.  Now it's not entirely clear if all these people in ancient times actually had what we now call leprosy, or if some might have had some other skin disease, but DNA tests have shown the bacterial disease we now call leprosy has been around for thousands of years.  It is also now called Hansen's disease, after the Norwegian doctor Hansen, who in the late nineteenth century first identified the bacterium that causes it.

As a bacterial disease, it can be cured with modern antibiotics, but there was no cure before the mid-twentieth century, and it is still fairly prevalent in some parts of the world, especially India.  The disease attacks the skin and the nerves, so that the infected person may not notice they have wounds, leading to loss of digits especially.  Someone with discolored skin, missing fingers, and maybe shuffling along half blind was frightening.  (Leprosy often infects the eyes.)

Medieval people both feared and pitied lepers.  Although leprosy was (and is) hard to catch, medieval people didn't want to take chances.  Thus lepers were isolated and were supposed to avoid the general population, ringing a bell if they had to go somewhere, to warn people to get out of their way.  The "unclean" of the Bible gave lepers a moral and social stigma, so they were not just frightening but despicable.  The disease has always spread more easily among those living very close together, especially the poor, and encampments of outcasts were "unclean" in the full sense of the word.

But medieval people also pitied lepers and wanted to be Christ-like and, if not actually cleanse them (heal them completely), at least help them.  Just as many hospitals were established in the twelfth and thirteenth centuries, hundreds of leper-houses were set up, essentially sanitariums where lepers would live isolated but properly taken care of.  These were called Lazarus houses, due to the belief that Lazarus, who Jesus brings back from the dead in the Bible, had died of leprosy.  (The Bible doesn't actually say he was a leper, but it's a good story.)

Fun fact:  The abbey of Fontevraud had a leper-house associated with it in the twelfth century, called appropriately St.-Lazare.  It has been remodeled into a luxury hotel.  I bet the Americans who stay there have no idea.  The Paris train station St.-Lazare is located on the site of a medieval leper house.

Leprosy reached the Pacific islands in the nineteenth century.  A leper colony was established on the island of Molokai in the Hawaiian islands, on a lava beach at the bottom of steep cliffs.  Lepers were rowed to nearby, pushed overboard and told to swim to shore.  A Catholic priest, Damien De Veuster, took care of them until he finally caught leprosy himself and died.  He has now been canonized as Saint Damien.  The lepers were there until the later twentieth century, when they were finally cured, though some stayed on at the colony, which had been their home for so long.  The Molokai tourist bureau offered tourists a chance to ride a donkey down the very steep cliff to visit the lepers.  (And they wonder why their island has no high-rise hotels.)
