Each year malaria claims 1 million lives; tuberculosis 3 million; diarrheoal disease 4 million. Most of these deaths are among the vulnerable (the very young or the aged). The annual death rate from AIDS is around 100,000 in 1993 and is expected to be 400,000 by the year 2000.
By the early 1990s amongst urban populations with a high prevalence of HIV in sub-Saharan Africa, adult mortality has risen and child mortality rates reverted to 1980 levels. In some African cities, eight hospital beds in 10 were occupied by AIDS patients. Asian nations could see a similar reversal of demographic gains by the end of the year 2000.
