In the interest of fairness, HIV has not been officially confirmed, his agent has only said he faces "medical problems" and tests showed "abnormal blood values".
Per the agent (Tekin Birinci) -
‘Eboue signed for a club and, as a normal procedure, we took him for a medical to check him out.’
‘They found abnormal blood values so they didn’t issue the licence and we took the decision to send him to England to have medical check-ups there.’
‘It’s wrong to say at this point he has HIV. Turkish news reports are wrong. I made it [Eboue’s situation] clear two days ago. Even if it will be true it shouldn’t be published like that.’
Regardless I do wholeheartedly agree with your sentiment and if true it definitely is upsetting.
However HIV when caught early can be very manageable and if a prominent figure such as this can help raise awareness perhaps it can help others get the help they need.
