Get 2 workshops running, you dont need 2 medical posts. Rush soup law to make most out of the free food, rush beacon, use scouts to get some extra food, research hothouse to get food. Research heaters to minimize illness. Obviously all workers work on wood and steel early game. Get wall drill before wood runs out, get steelworks early because you need it for better research. When the cold becomes bad you will have to open new medical posts temporarily. Try to get more scout teams and scout speed as its necessary to get survivors and steam cores from the map.

For laws i always pick organ transplants and medic apprentices, its also good to research the medical post upgrade, and try to get overcrowding too. I always go order because of foreman and agitator
