>>14237779Since much of the spread of TB to the US comes from other countries, immigrant groups/ethnicities are also more vulnerable, so there's huge overrepresentation in Asians, some in Latinos and a bit for black people. I'd wager most of the African-American cases are actually African immigrants/recent travelers because for such a low number of total cases and the massive amount of TB spread in Africa that seems most likely.
>>14237915Jews have a shit ton of religious rules regarding cleaning hands, avoiding dirty things like bodies, etc. that explain much of their disease resistance during the Middle Ages, notably the black death. These days there's more urban than rural cases, the former just get better care overall, particularly in the developing world.
