(CNN) - The mysterious castaway who turned up in the Marshall Islands last week has been released from a hospital.
Jose Salvador Alvarenga had been re-admitted Thursday amid concerns his health was deteriorating.
Doctors reported that he was severely dehydrated, deficient in vitamins and suffering from swollen legs.
Alvarenga's tale of surviving 13 months adrift in the Pacific Ocean has prompted fascination and skepticism.
He left the hospital Friday and is now staying at a hotel in Majuro, the capital of the island chain.
