Gays in general will be wiped out. Gay Hollywood and entertainment will be gone. Gay politicians will be gone. (There is one politician in particular that I suspect has HIV. If he has it, I hope he gets TBOS.) Gay marriage will be forgotten.
The elderly will be wiped out.
The ghettos will be essentially depopulated. The poor will otherwise suffer huge percentages of deaths because they live in congested areas and many of the poor already have bad health.
Children will be hit hard because they tend to be congregated in places like Government schools.
There will be so much overall loss of life that birth control pills and condoms will cease to be free for single females. Society will direct a volcanic wrath on them and tell them to find a man, marry him, stay at home, and produce many children. Single women will no longer be welcome in the work place, and society will be yelling at men and telling them to go back to work. Any single woman who has an abortion will be looked at like she has leprosy. Feminism will be gone.
The death rates differ by ethnicity ~ some groups are more readily wiped out than are others. I've never read much about age group differentials ~ although there is one for pneumonia ~ which might be what you are thinking about.
I suspect it will have an imprint rather like that of hanta virus. The young adults will die first simply because more of them are out socializing ~ at work, at play, and wherever. The very young, and the elderly will be hit less often. You'll end up with a civilization bracketed by the old and the young ~ and only those societies heavily mechanized, automated, computerized, roboticized and using the latest in modern work methods will survive as civilizations. The rest will collapse into the dustheaps of history ~ much as they did back in the mid 1400s to 1600s in the Americas.
We would also see a scream to close the border. So many TB cases are illegal immigrants coming across the border to work, and they can spread the disease to the already ill in hospitals, the elderly in nursing homes and very young in childcare facilities. The parents of infected young children and parents will be less likely to use such facilities in the future, or to permit the hiring of illegal immigrants in the future.
