Coping with the Krieger Strain, How to deal with it, who you can contact Options

[kryton]

I've got some players who have been doing some work for Tamenous. My campaign takes place in 2065 after the Crash in Boston. Basically Right after the nuke goes off. (When the players saw the blimp acting funny they hit the floor.)
In trying to survive after the big one hit Boston, they did a favor for a local underground king pin as mentioned in Target UCAS. In doing that job they were given some injectable "meds" tainted with the "Krieger Strain" slowly turning them into ghouls. The campaign has been enjoyable as they have noticed slow and gradual "changes". One player had a fake ID and went to Mass Generals Clinic to get tested, which came back positive. (They immediately tried to trace the call and the players location when calling him back with the results.)

So I'm deciding what they can do as they don't want to be Ghouls. There isn't an "official cure" for becoming a ghoul but there might be antiviral drugs that "slow the progression" similar to AZT and Aids in the middle to late 1980's.
I figure two things:

A. The drugs are very expensive and they make a good leash for they're masters to control them with. (Having them might be illegal as being a Ghoul is illegal, probably the drugs are just hard to get hold of and are thus difficult to get.)

B. Maybe there's some sort of artifact that might have the power to heal. I'm thinking a Cure Disease spell just won't cut it as this is a retro-viral infection and not a straight pathogen. That could make for a fun side plot in my "campaign".

C. A bullet to the brain will always cure the disease, but it does have a nasty "side effect" that's a bit extreme. (The players who are not infected are thinking about offing them and trying to turn the corpses in for a reward.)

I'm just curious to know what folks think about this? How would you handle this type of "change" that the Players are going through?
