In my short story, there is (today) technology to "bring back" the recent dead. Joanna Public dies of exposure and is found a week later in the woods a few miles outside of Portland, Oregon. Luckily Joe Doctor can 're-animate' her to her mental self fully.
This is not like a zombie movie, she's fully capable, very happy to be back albeit a little bit stiff (ha) but had to have a lot of cleaning up and there are bugs and things.
Then this starts to be common practice that can happen only a few weeks after death, and obviously not if someone was embalmed or cremated. It is for people who have died of natural causes.
In my story, I want to know what are the implications of infectious disease, from bringing people back who have been exposed to decomposition. This is not a zombie story. I must use that tag, though, because I can't think of much else to describe it. They are mentally and happily back to normal; setting aside the science to bring them back, what (existing) diseases could they spread?
