Acquired Immunodeficiency Syndrome (AIDS) cases surged globally since 1981, with rapid increases in Asia. Recommended treatments now include combination therapies with nucleoside analogues.

Area of Science:

  • Epidemiology
  • Virology
  • Public Health

Background:

  • Acquired Immunodeficiency Syndrome (AIDS) emerged in 1981, with global cases estimated at over 6 million by late 1995, though reported cases were significantly lower.
  • A concerning 20% annual worldwide increase in AIDS cases was observed, with Asia experiencing an exceptionally high growth rate exceeding 150% annually.
  • The Human Immunodeficiency Virus (HIV) exhibits significant diversity, with HIV-1 classified into two main groups (M and O) and HIV-2 having at least five subtypes, primarily found in Africa.

Purpose of the Study:

  • To provide an overview of the global AIDS epidemic's scale and growth.
  • To detail the classification and diversity of HIV-1 and HIV-2.
  • To highlight current treatment recommendations for AIDS.

Main Methods:

Related Experiment Videos

  • Epidemiological data analysis from the World Health Organization (WHO).
  • Review of HIV classification systems and subtypes.
  • Summary of recommended therapeutic interventions.

Main Results:

  • By late 1995, over 6 million AIDS cases were estimated globally, with only one-third reported.
  • Significant regional disparities in growth rates were noted, particularly the rapid increase in Asia.
  • HIV classification includes diverse subtypes within both HIV-1 and HIV-2.

Conclusions:

  • The global AIDS epidemic presented a substantial and growing public health challenge as of 1995.
  • Understanding HIV diversity is crucial for developing effective interventions.
  • Combination therapies utilizing nucleoside analogues are the recommended treatment approach.
