Interesting but hard riddle?

My friend showed me this riddle and its hard to answer





Percy has two problems. He must be operated on for appendicitis, and at the same time he has a highly infectious disease that will infect anyone who touches his bare skin. Three surgeons must operate on him one at a time. The first is Dr. Vern, the second is Dr. Hortence, and the third is Dr. Rufus. Each surgeon must wear rubber gloves on each hand when he or she operates. Percy’s disease will contaminate the outside of any glove worn.





Percy definitely has the disease. In addition, one of the doctors may have the disease, but you do not know which one.





As the operation begins, Nellie Nurse said, “Oh, no! We only have two pairs of sterile gloves.” No more gloves are available. None can be sterilized in time. The doctors must operate immediately.





How do the doctors operate without contaminating each other? Nellie Nurse knows. Do you?

Interesting but hard riddle?
Maybe 2 of the doctors can operate one handed and share a pair of gloves?


Or, if one of the doctors is operating on him to cure the skin disease, just let him go first.





Ooh! I think maybe I have it.


OK, so the first doctor puts of both pairs of gloves. So when he's done, the inside of the outside pair is clean. So the second doctor wears the outer pair that the first doctor had on.


Then, the third doctor wears the inside pair that the first doctor wore - but inside out. The outside of that pair were never contaminated because of the second pair.





I hope that makes sense. Is that the answer???
