Jesus did. He lives today in all God's Children, "walking through the cities of the plague (Dylan)." As Scripture says, "to the pure all things are pure," and the grand truth is that when lepers begged to be touched by Christ and He reached out his hand, embracing them with all His will, the lepers were healed, while He remained immune to their infection. Awesome, Holy God.
Thank you for you insihgts. If Jesus could doesn’t mean we can. Leprosy is not very contageous unlike its first cousin tuberculosis. You could live for years among lepers and never catch the disease. But what is called leprosy in the Bible is not Hansen’s Disease (true leprosy) but more like psoriasis or similar (non-contageous) dermatological condition. True leprosy was unknown in the Middle east during Jesus’ times.
