Paul Brand said this quote

“ I have sometimes wondered why Jesus so frequently touched the people he healed, many of whom must have been unattractive, obviously diseased, unsanitary, smelly. With his power, he easily could have waved a magic wand. In fact, a wand would have reached more people than a touch. He could have divided the crowd into affinity groups and organized his miracles--paralyzed people over there, feverish people here, people with leprosy there--raising his hands to heal each group efficiently, en masse. But he chose not to. Jesus' mission was not chiefly a crusade against disease (if so, why did he leave so many unhealed in the world and tell followers to hush up details of healings?), but rather a ministry to individual people, some of whom happened to have a disease. He wanted those people, one by one, to feel his love and warmth and his full identification with them. Jesus knew he could not readily demonstrate love to a crowd, for love usually involves touching. ”
