Guidance on couples HIV testing and counselling, including antiretroviral therapy for treatment and prevention in serodiscordant couples

New WHO guidelines recommend offering HIV testing and counselling to couples, wherever HIV testing and counselling is available, including in antenatal clinics. For couples where only one partner is HIV positive, the guidelines recommend offering antiretroviral therapy to the HIV positive partner, regardless of his/her own immune status (CD4 count), to reduce the likelihood of HIV transmission to the HIV negative partner.
