for most of us who live in the urban areas it would be hard to see much of a difference as in improvement of people´s standard of living ..but the rural and underdeveloped areas will tell you.
I am from Natal....well i was born there and the way of life back then was slow and very lacking in terms of health facilies...
I went back recently and there is an infrastructure now in place catering for health and Aids education ectc etc...
To answer your question i think the govement is putting considerable amout of effort....i belive they have done a remmarkable job in building awareness and i think awareness is a major step in conquering this diesces..
other than that i am not too sure..and i do think the gvt can do enough
too many lives have been lost already all the govement can do is try and save the remaining lives..
