What precautions to Morgues/Funeral Parlors/ect. take against Shedim in 2075.
According to Street Magic (4th edition), many bodies are cremated to prevent shedim infestation.
Is the threat not as serious?.. something that happens rarely.
There hasn't been a shedim report since Ghostwalker closed the DeeCee rift. Doesn't mean they aren't there, or can't come back, but it hasn't happened in years.
Can Shedim Possess a headless corpse?
I assume so. Never heard of it happening, but the possession (as near as I can tell) is more spiritual than anything else. When the spirit has left the body, the body becomes an unused vehicle, essentially. So without a head the shedim wouldn't be able to do anything that a person without a head could do, but they could at least animate and stumble.
Do most hospitals have magic wards in 2075?
Some do, sure. There's always the possibility for spirits and/or paracritters to try to get into a hospital. Not to mention ghouls and other infected that can perceive astrally. I can't even imagine the HIPPA rules for assessing.
Next run my players are more than likely going to be trying to get to a dead body getting an autopsy in a morgue.
Sounds good. If you're willing to play with the rules a bit, you could create a situation with a possession mage trying to find bodies for possession. Or you could have a gang getting their "green wings" in the morgue. And of course, there's always people who attempt to steal from the dead, whether it's as simple as someone pulling teeth for fillings or Tamanous pulling bodies for parts.
