Prince contracted HIV in mid-90s but condition developed into AIDS six months ago, anonymous sources have claimed.
A source, who was not identified by the Enquirer, said: 'Doctors told Prince his blood count was unusually low and that his body temperature had dropped dangerously below the normal 98.6 degrees to 94 degrees.
'He was totally iron-deficient, very weak and often disoriented. He rarely ate and when he did, it all came right back up.
'His face was yellowish, the skin on his neck was hanging off and the tips of fingers were a brownish-yellow.'
