Could HAART treatment strategy reduce HIV?

A new strategy to battle HIV might reduce the epidemic of HIV/AIDS. Dr. Julio Montaner, of the B.C. Centre for Excellence, suggests using HAART as treatment for HIV could lower the number of cases around the world. HAART reduces viral loads of HIV in the patient's blood until it is undetectable, and as a result they become less infectious. A patient going on HAART soon after testing positive to HIV lessens the transmission of the virus. Montaner adds, "It's time that we start talking about it, and the Center would like to lead that discussion because if that is the case between better prevention and strengthening of our treatment programs we may be able to, at least in the short term, control the spread of HIV." Convincing people who have already tested positive to HIV is a very heavy task. Why would you want to take medications when you are not sick? Is this one more way of prevention? Or is it suggesting something else?
