I told Mom that. People stopped seeing him because it doesn't work, and he may have assumed they recovered. He gave an anecdote about someone in their mid-20s who was a high-level table tennis player. He got ME, saw him, eventually completely recovered and returned to playing ping-pong even better than before, and went to the Olympics. I presume he was one of the 5% who recover naturally.
Professional tennis players in the past got EBV and recovered, some haven't returned to previous health and had to retire.
