A.I.D.S., Africa, And Heterosexuals (Press, 11 February 1986)

On 11 February 1986, “The Economist” published an in-depth examination of the spread of acquired immune deficiency syndrome (A.I.D.S.), tracing its origins and transmission patterns, particularly in Africa. The article suggests that A.I.D.S. likely began in Africa, emerging predominantly as a heterosexual disease, and is now spreading from a core area located between eastern Zaire and western Uganda, where infection rates may stand at one in ten. The situation in Rwanda seems particularly dire, with alarming data collected by Belgian scientists indicating that approximately 18 per cent of hospital workers and 17.5 per cent of young adults in Kigali have antibodies for the virus. Furthermore, 10 per cent of blood donors in Rwanda are infected, and the scientists suspect that heterosexual contact, especially with prostitutes, is the primary means of transmission. Investigations revealed that societal norms, such as a high age of first marriage and sexual abstinence after childbirth, might push men towards prostitution, thus increasing the risk of infection. Records from Nairobi indicated a worrying increase in the number of infected prostitutes, suggesting a growing crisis. However, the article notes other views regarding the spread of A.I.D.S., proposing that conditions like gonorrhea and syphilis could exacerbate transmission through physical lesions. There’s also a discussion on the reuse of hypodermic needles among sex workers, which could contribute to the spread, but the correlation between needle use and infection appears less pronounced than that of sexual behaviour. The narrative shifts towards the understanding of A.I.D.S.'s transmission dynamics. The number of sexual partners one might have plays a crucial role in the potential growth of an epidemic. Dr Douglas Feldman from New York University reported that modern practices among prostitutes, such as insisting on condom use, could help mitigate the spread. However, his studies in Rwanda revealed a concerning gap in knowledge about the virus, as many were unaware of the main method of its transmission. The article also deliberates on the origins of the A.I.D.S. virus, postulating that it may have evolved from a similar virus found in particular monkeys, given the genetic similarities. Although early blood samples from Africa suggest traces of the disease predating the widespread outbreak, it remains uncertain if A.I.D.S. was a rare presence before 1978 or if it sporadically arose from animal sources. Current research supports the notion that many Africans might be reacting to a benign version of the virus from monkeys rather than the harmful human version, which raises questions about the dynamics of immunity in the population. Ultimately, the article presents a landscape where A.I.D.S. could serve as a predictor of future health challenges in urban settings globally, suggesting an urgent need for increased awareness and effective public health campaigns, specifically around the use of condoms to curb transmission rates and combat the disease's spread.
