Dr Olwen Williams of St Asaph reveals the ground-breaking research that has uncovered the birthplace of the virus on S4C The HIV/AIDS virus has claimed more lives than any other virus – over 40 million people throughout the world over the last 30 years. But where did the virus come from and how did it spread so quickly?In a special S4C documentary AIDS: Cyfrinach y Congo (Aids: The Secret of the Congo) the sexual diseases advisor, Dr Olwen Williams of St Asaph reveals the ground-breaking research that has uncovered the birthplace of the virus.The programme follows a team of international scientists as they track down the roots of the virus in the Democratic Republic of Congo and Cameroon in Central Africa.Dr Williams said, “When I began my career in the 1980s nobody knew what was causing this new illness. We all thought AIDS was an illness of homosexual men. People with the disease were stigmatised very quickly and the stigma continues today.”Dr Dirk Teuwen, a medical researcher from Belgium, leads the team of international scientists who are leading the way in the research.He said: "We knew that Kinshasa, capital of the Congo, was the epicentre of HIV1. Kinshasa was the starting point but where did the virus have its roots?"By the 80s Kinshasa was being swamped by the virus and the programme reveals that there was a link between the Congo’s internal conflicts of the 60s and the story of AIDS and its source.There is a close connection between AIDS and another virus infecting some creaturesIt also reveals that people were being infected with the virus long before the first cases were seen in the countries of the west.In a hospital in Mbanza-Ngungu, a town in western Congo, the crew of researchers discover old samples from dead bodies in a store.There they find three positive AIDS samples dating back to the 60s. This leads the team to conclude that there were a very large number of cases of AIDS in the Congo in the 60s without anyone realising it.RELATED: Parents demand public apology after son's tragic deathBut where was the virus before it reached the Congo? Virologist, Professor Beatrice Hahn of Philadelphia explains the close connection between AIDS and another virus infecting some creatures. Professor Hahn said: “In rural parts of Africa people eat monkeys and chimpanzees as part of their diet without knowing the animals are dying from their own type of HIV, very much like the human virus.”Dr Teuwen travels more than a thousand miles from Kinshasa to the west of Cameroon. After a long and difficult programme of research, the team discover several strains of a type of HIV in chimpanzees’’ excrement.The virus dates back to more than a century agoDr Teuwen concludes that AIDS had spread to Kinshasa from Cameroon, the birthplace of the virus for differing reasons including the valuable timber business between Cameroon and the rest of the world, new transportation systems, a network of rivers and people’s sexual practices. He also concludes that the virus dates back to more than a century ago.Among other contributors to the programme is Professor Peter Piot, former United Nations Director of Aids, one of those responsible for discovering Ebola.He said: “We wasted so much time in dealing with HIV and recognising it as a problem. In the 80s at the beginning of the epidemic had we had a massive effort by the global community, even in the absence of drugs, we could have saved millions of lives.”
