What did Raffaello Sanzio die of?

Raffaello's premature death on Good Friday (April 6, 1520) (possibly his 37th birthday), was caused by a night of excessive sex with Luti, after which he fell into a fever and, not telling his doctors that this was its cause, was given the wrong cure, which killed him.
He never told his doctor the truth about what caused him to be sick and therefore was given the wrong cure for his disease which cost him his life 15 days later.
