I'm trying to find the name of a Choose Your Own Adventure book I recall reading when I was a kid (this was in the late '90s).
The protagonist is an adventurer, and you join a team of doctors/scientists who are shrunk in size to be able to enter a human body. You enter the body of a medical scientist who is in some kind of coma after an explosion (I think) in his lab. He had discovered the cure to a disease that is ravaging the planet, and you and your compatriots need to enter his body to repair the damage so he can wake up and tell you the cure to the disease. You and the others travel inside the body in some kind of microscopic craft/capsules that you can control. I think the craft are camouflaged to look like normal cells in the human body.
Along the way it turns out that one of the other scientists is a traitor who did the sabotage that caused the explosion.
Thanks for your help!
