Publicity The Key To Battling A.I.D.S. (Press, 4 September 1989)

In a commentary on the HIV/AIDS crisis in New Zealand, Dr Tessa Turnbull from the Royal New Zealand College of General Practitioners highlights the significant presence of HIV, the virus responsible for AIDS, within the country. While research is underway to find a cure, and international symposiums are facilitating the sharing of knowledge, Turnbull notes that considerable government funding has focused on public education campaigns. The predominant message has been to promote safe sex practices, such as condom use, alongside implementing a needle exchange scheme to reduce the transmission risks associated with drug use. This public health approach also includes improvements to blood transfusion safety through rigorous HIV antibody testing and discouraging high-risk individuals from donating blood. Despite this awareness, Turnbull emphasises that the majority of AIDs cases currently observed could only represent a fraction of future incidences due to the lengthy incubation period from HIV infection to AIDS, which is estimated to be at least seven years. This leads to critical questions about the allocation of resources and whether funds are being used effectively, especially in the context of ordinary heterosexual individuals in developed nations. Turnbull observes that information gleaned from overseas studies demonstrates rapid spread of HIV/AIDS in heterosexual urban populations of central and eastern Africa, where societal conditions differ drastically from those in New Zealand. Factors contributing to this include multiple sexual partners, a prevalence of prostitution, high rates of other sexually transmitted infections that facilitate HIV transmission, and various chronic infections that can weaken immune systems. A recent European study showed that the likelihood of AIDS transmission from infected males to their female partners increases significantly if the female has a history of sexually transmitted infections or if the male has advanced AIDS. The risk level also escalates with the practice of anal intercourse. Interestingly, the study found that having repeated sexual contact does not necessarily increase transmission rates as long as no risk factors are present. In New Zealand, drug addiction and the sharing of needles are considered high-risk activities, as is homosexual activity without adequate protective measures. The prevalence of sexually transmitted diseases in New Zealand also poses an elevated risk for HIV/AIDS, underscoring the need for widespread public education about these factors. The case of an infected prostitute in Sydney has further amplified concerns regarding indiscriminate sexual behaviour, making it evident that managing such risks is a complex issue. While the risk in a single heterosexual encounter is deemed low, Turnbull affirms that the threat of AIDS is real, necessitating the implementation of control measures and increased public awareness of risk factors. She concludes that ongoing research and education will be vital in addressing and managing this public health concern as knowledge about HIV/AIDS continues to evolve.
