According to wiki the fellow has had to publicly state neither he nor his church offers and alternative to convention medical pracicise for AIDS/HIV:
SCOAN remains controversial both in Nigeria and abroad, claiming regular occurrences of divine miracles. Several hundred Nigerians and international visitors come to the SCOAN each week to register for the prayer lines where the visitors are prayed over by T.B. Joshua and the "Wise Men". SCOAN has published numerous videos claiming to document the healing of incurable disabilities and illnesses such as spinal cord injuries, HIV/AIDs[2][3][4] and cancer.[5] Notable sportspersons who claim to have been healed of sporting injuries at the SCOAN include South African rugby players Jaco van der Westhuizen[17] and Jaco du Preeze, and Nigerian footballer Joseph Yobo.[18] In November 2011, Pastors from the church were caught on camera claiming to have healed people with HIV/AIDS and recommending that they stop taking life-saving antiretroviral medications.[6] Following the publication of this report, T.B. Joshua stated shortly thereafter that he fully supports medical science and the standard treatment of HIV/AIDS.[citation needed]
Spiritual healing at The SCOAN has been mentioned by Time magazine.[19] Since June 2010, five "Wise Men" have joined in ministering to people at The SCOAN, purportedly able to prophesy, heal and deliver in the same vein as T.B. Joshua.[20] The church has branches in Ghana,[21][22][23] the United Kingdom,[24] South Africa,[25][self-published source] and Greece.[26]
