    Current and future dimensions of the HIV / AIDS pandemic: a capsule summary.

    World Health Organization [WHO]. Global Programme on AIDS

    [Unpublished] 1992. [2], 15 p. (WHO/GPA/RES/SFI/92.1)

    A summary of current state and future trends to HIV infections and AIDS cases in world regions prepared from the most recent information on file at the WHO Global Programme on AIDS as of January 1992. HIV infection and AIDS began in the 1980s or earlier in homosexual or bisexual men and intravenous drug users in urban Americas, Australia, and Western Europe, and in heterosexuals in East and Central Africa. There is another virus called HIV-2 with a lower virulence, but similar mode of transmission and clinical syndrome prevalent in West Africa. By 1992 450,000 AIDS cases were reported to WHO, but about 1.5 million AIDS cases are thought to have occurred, including 500,000 in children. About 9-11 million HIV infections, including 1 million in children, are estimated to exist. In Australia, North America, and Western Europe, spread of HIV to homosexuals has decreased, but growth in the intravenous drug-using population and heterosexuals may still occur. In Latin America prevalence is high in homosexual or bisexual men, injecting drug users, and prostitutes, and is increasing dramatically in women. In Africa heterosexual transmission is still the rule; infections from blood products account for about 10% of cases. In East and Central Africa 2/3 of the HIV cases are in 9 countries, where urban HIV prevalence reaches 25-33% in adults. In Africa there is also a growing problem of 750,000 pediatric AIDS so far, and possible 10 million orphans in the 1990s. Spread of HIV in high risk populations in South East Asia is rapid, notably in Bangkok, Thailand, in Yangon, Myanmar, and in Bombay and in northeastern India. The potential for spread in this region is a great concern. Areas of East Asia contiguous with South East Asia are also at risk. In Eastern Europe there are clusters of outbreaks related to improper use of blood products. WHO predicts that 4 million people have HIV and TB. WHO projects that global HIV infection will amount to 15-20 million by 2000. A major research topic and concern is estimation of when and at what level HIV prevalence will peak in world regions.
