HIV and AIDS Ambassador, Joyce Dzidzor Mensah, will appear before Ghana AIDS Commission Board later Wednesday following her controversial claim she has never contracted the virus.

When Ms Dzidzor appears before the Commission this morning, she will be probed about details of her controversial revelations.

Director of the Ghana AIDS Commission, Angela El-Adas, says Ms Mensah's invitation is crucial to understanding her new stance on her HIV status.

Joyce Dzidzor Mensah, last Monday shocked the nation by declaring that contrary to popular belief, she is not HIV positive.

She says she has been lying for the past four years about her HIV status despite educating people on the disease and campaigning against HIV/AIDS stigmatisation.

The Ghana AIDS Commission however insists Ms Mensah tested HIV positive in 2007.

"Many of our media partners have been trying to attribute all kinds of reasons for what is happening now. Even some of our [donor] partners have done that", Dr El-Adas said.

She said the outcome of today's encounter with Ms Mensah will determine the way forward on the matter.
