Actually, they have evidence that circumcision does reduce the risk of a man getting HIV during normal sex (IIRC, it is a large decrease in risk). The folds of skin trap the virus apparently. As with many Jewish traditions, circumcision is a health based practice as is Kosher. In Leviticus, work practices for mold remediation were spelled out and the Rabbi acted as the consultant on mold issues.
34 When ye be come into the land of Canaan, which I give to you for a possession, and I put the plague of leprosy in a house of the land of your possession;

35 And he that owneth the house shall come and tell the priest, saying, It seemeth to me there is as it were a plague in the house:

36 Then the priest shall command that they empty the house, before the priest go into it to see the plague, that all that is in the house be not made unclean: and afterward the priest shall go in to see the house:

37 And he shall look on the plague, and, behold, if the plague be in the walls of the house with hollow strakes, greenish or reddish, which in sight are lower than the wall;

38 Then the priest shall go out of the house to the door of the house, and shut up the house seven days:

39 And the priest shall come again the seventh day, and shall look: and, behold, if the plague be spread in the walls of the house;

40 Then the priest shall command that they take away the stones in which the plague is, and they shall cast them into an unclean place without the city:

41 And he shall cause the house to be scraped within round about, and they shall pour out the dust that they scrape off without the city into an unclean place:

42 And they shall take other stones, and put them in the place of those stones; and he shall take other morter, and shall plaister the house.

Actually, kosher has NOTHING AT ALL TO DO WITH HEALTH. I can't believe that anyone believes that religious prohibitions on food from thousands of years ago were based on health principles.
The prohibition of meat w/milk ( not seething a kid in its mother's milk) was a prohibition of Egyptian religious rituals dedicated to Isis/Astarte. The kid seethed in milk was a ceremony of rebirth. Shellfish were also a part of goddess worship, consumed as aphrodisiacs prior to orgies in her honor. The pig was likewise a sacred animal in much of the pagan world, in Egypt, as well.as for the Celts.
I could go on about the foreskin and child sacrifices to the god Moloch, but I.m writing on a cellphone. It's all written about by Robert Graves and Sir James Frazier et al.
Nothing you wrote about leprosy and cleaning a house has to do with circumcision per se.
