The World Health Organization (WHO) estimates that the world total of AIDS cases will reach 300,000 by the end of 1988 and 500,000 to 3 million over the next 5 years. AIDS is of special concern to developing countries with their limited, stressed health care systems and the other serious health problems of their populations. Also, AIDS usually strikes the young and productive adults that the economies of these countries can least afford to lose. The Surgeon General of the Public Health Service has challenged the United Nations to make the world's blood supply safe by 1991. Private and public sector leaders could come together, apply the technology and resources available in industrialized countries, and achieve a victory in this facet of the AIDS pandemic. The WHO's global strategy has led to the establishment of national AIDS committees in 151 countries and the preparation of 70 short-term (6-12 months) plans and 25 medium-term (3-5 years) plans for national AIDS control programs.
