AB OBJECTIVE: To estimate the possible impact of changes in sexual
behaviour, increased access to STD treatment and effective blood
screening on future HIV incidence in developing countries. METHODS:
Available behavioural data and a Monte-Carlo simulation model
(SIMULAIDS) were used to estimate the number of new HIV infections that
could be averted if certain behaviour changes were induced and
sustained. Based on previous cost estimates of prevention interventions,
the cost-effectiveness of global preventive efforts was assessed.
RESULTS: According to GPA's projections, a total of 19.5 million new
adult HIV infections would occur in developing countries between 1992
and 2000. If the changes as defined above take place in all regions
starting in 1993 and are maintained thereafter due to continuous
prevention efforts, an estimated 10 million HIV infections could be
averted by the year 2000, which represents a 57% reduction in new
infections. About 4.2 million could be averted in Africa, 4.8 million in
Asia and 1 million in Latin-America. Cost per DHLY saved would be $50 to
$100. CONCLUSION: This is the first attempt to estimate the impact a
worldwide AIDS prevention effort would have on future HIV infections,
showing that a dramatic decrease in the spread of HIV could be achieved.
The cost of implementing preventive interventions in all developing
countries is high ($1.3 to $2.5 billion), but the cost per DHLY gained
is reasonable.
