Agree on replacement.
I was aging a game and by the late Prehistoric era I ended up with like 23 health and 7 unhealthy. I think buildings that have to do with fertility, skin puncturing, or lots of people in the same area and meat need some unhealthy.
Childbirth Hut
Fertility dance
Slaughter house
Butchery
Blood Dance
Bloodhuntress hut
Branding hut
Childcare hut (kids next to each other spread disease fast)
Harem
Tattoo hut
Piercings hut
Graveyard
We can give those buildings a +2 Disease and 1 unhealthy.
I think the Flammability of fire dance needs to be reduced to make it more attractive.
1. Childbirth Hut is only +1

so I am going to say we should leave that the way it is.
2. Fertility Dance should not have it nor do I think it should have the +2

. Instead give it Cities Require +2% less

. to grow. To simulate having babies.
3. Slaughter house is technically still more sanitary than just buttering it on the ground. So I would say no

to but also no to

. They cancel out.
4. Blood Dance already gives disease. I think that is more than enough penalty for its limited benefits.
5. Bloodhuntress hut I suppose, but then the

will cancel out the food bonus.
6. Branding hut - But you said this was to cauterize wounds so it has +1

. That;'s about the only things going for that building.
7. Childcare hut well you have it give -2 disease. Having a

would be counter productive. Perhaps instead ...
Childcare Hut
- +2

- +2 Education (primitive teaching)
- -2 Crime (keeping from getting in trouble)
Note the disease is just removed since they are healthier than being out on their own but also get sick faster from being around others.
8. I can see it for the Harem. How about gives +1

and +5 disease. Note that the brothel has +5 disease so its equal disease spreading and then the +1

from not screening them for STDs like a brothel would do.
9/10. Tattoo hut and Piercings hut already give +1
11. Graveyard should not give

because its putting people in a place away from people to decompose. Thus it reduces disease and gives

. And its so expensive that its worth it.
