As of September 30, 1991, the World Health Organization reported that 163 countries and regions worldwide had identified AIDS cases, with over 410,000 patients. By the mid-21st century, the number of AIDS patients is expected to increase by 20 to 30 times, reaching approximately 10 million. The AIDS virus was first identified in 1983, with research teams led by Luc Montagnier at the Pasteur Institute in France and Robert Gallo at the National Cancer Institute in the United States announcing the discovery. However, the earliest known AIDS patient dates back to a British sailor in 1959. His case suggests that the AIDS virus may have existed as far back as 50 to 150 years ago. Currently, there are three main hypotheses regarding the origin of AIDS: "introduced from outer space," "transmitted from monkeys to humans," and "artificially created." These hypotheses have sparked extensive discussion and controversy, and a definitive conclusion remains elusive.
Despite significant advancements in medicine, many mysteries surrounding the origins of AIDS remain unsolved. This issue is not only a medical concern but also a historical and cultural one, deserving of deeper exploration.
