Denialism undermines AIDS prevention in sub-Saharan Africa

Conflicting Views in Narratives on HIV Transmission via Medical Care

Molecular studies suggest that HIV arose in Africa between 1880 and 1940. During this period, there were campaigns by European colonial governments that involved unsterile injections of large numbers of Africans. That, along with other unsafe therapeutic interventions, may have propelled the evolution of HIV from SIV. Since subtype B in Africa may have been concentrated in white African homosexuals, it is possible that Westerners rather than Haitians introduced the virus to the New World. Amplification of HIV subtype B took place in Haiti, where transmission was facilitated by hazardous medical procedures including plasmapheresis. Representations in the media, however, largely ignore Western contributions to the spread of AIDS. This article focuses on the value of alternative narratives in fostering a balanced view that is less stigmatizing on developing nations.

An AIDS-denialist online community on a Russian social networking service: patterns of interactions with newcomers and rhetorical strategies of persuasion

BACKGROUND

The rise of social media proved to be a fertile ground for the expansion of the acquired immune deficiency syndrome (AIDS)-denialist movement (in the form of online communities). While there is substantial literature devoted to disproving AIDS-denialist views, there is a lack of studies exploring AIDS-denialists online communities that interact with an external environment.

OBJECTIVE

We explored three research areas: (1) reasons for newcomers to come to an AIDS-denialist community, (2) the patterns of interactions of the community with the newcomers, and (3) rhetorical strategies that denialists use for persuasion in the veracity of their views.

METHODS

We studied the largest AIDS-denialist community on one of the most popular social networking services in Russia. We used netnography as a method for collecting data for qualitative analysis and observed the community for 9 months (at least 2-3 times a week). While doing netnography, we periodically downloaded community discussions. In total, we downloaded 4821 posts and comments for analysis. Grounded theory approach was used for data analysis.

RESULTS

Most users came to the community for the following reasons: their stories did not fit the unitary picture of AIDS disease progression translated by popular medical discourse, health problems, concern about HIV-positive tests, and desire to dissuade community members from false AIDS beliefs. On the basis of strength in AIDS-denialist beliefs, we constructed a typology of the newcomers consisting of three ideal-typical groups: (1) convinced: those who already had become denialists before coming to the group, (2) doubters: those who were undecided about the truth of either human immunodeficiency virus (HIV) science theory or AIDS-denialist theory, and (3) orthodox: those who openly held HIV science views. Reception of a newcomer mainly depended on the newcomer's belief status. Reception was very warm for the convinced, cold or slightly hostile for the doubters, and extremely hostile or derisive for the orthodox. We identified seven main rhetorical strategies of persuasion used by the denialists on the "undecided".

CONCLUSIONS

Contrary to the widespread public health depiction of AIDS denialists as totally irrational, our study suggests that some of those who become AIDS denialists have sufficiently reasonable grounds to suspect that "something is wrong" with scientific theory, because their personal experience contradicts the unitary picture of AIDS disease progression. Odd and inexplicable practices of some AIDS centers only fuel these people's suspicions. We can conclude that public health practitioners' practices may play a role in generating AIDS-denialist sentiments. In interactions with the newcomers, the experienced community members highlighted the importance of personal autonomy and freedom of choice in decision making consistent with the consumerist ideology of health care. The study findings suggest that health care workers should change a one-size-fits-all mode of counseling for a more complex and patient-tailored approach, allowing for diversity of disease progression scenarios and scientific uncertainty.

Sexually transmitted infections and male circumcision: a systematic review and meta-analysis

The claim that circumcision reduces the risk of sexually transmitted infections has been repeated so frequently that many believe it is true. A systematic review and meta-analyses were performed on studies of genital discharge syndrome versus genital ulcerative disease, genital discharge syndrome, nonspecific urethritis, gonorrhea, chlamydia, genital ulcerative disease, chancroid, syphilis, herpes simplex virus, human papillomavirus, and contracting a sexually transmitted infection of any type. Chlamydia, gonorrhea, genital herpes, and human papillomavirus are not significantly impacted by circumcision. Syphilis showed mixed results with studies of prevalence suggesting intact men were at great risk and studies of incidence suggesting the opposite. Intact men appear to be of greater risk for genital ulcerative disease while at lower risk for genital discharge syndrome, nonspecific urethritis, genital warts, and the overall risk of any sexually transmitted infection. In studies of general populations, there is no clear or consistent positive impact of circumcision on the risk of individual sexually transmitted infections. Consequently, the prevention of sexually transmitted infections cannot rationally be interpreted as a benefit of circumcision, and any policy of circumcision for the general population to prevent sexually transmitted infections is not supported by the evidence in the medical literature.

AIDS epidemiology in Africa: a changing of the guard

With recent implementation of studies specifically designed to empirically assess the contribution of both sexual and blood-borne exposures to local HIV transmission in sub-Saharan Africa, and with the arrival of a new generation of investigators, a picture of HIV transmission routes of improved validity is emerging. Seven years ago the International Journal of STD & AIDS (IJSA) began actively encouraging reexamination of the prevailing view that penile-vaginal sex was driving African HIV epidemics, welcoming debate via manuscript submission and presentation of fresh scientific evidence. Although the IJSA-published dissenting views have largely been ignored, dismissed or fiercely resisted by established HIV researchers and allied health agencies, new approaches may yet elicit more rational, evidence-based responses. Several such contributions appear in IJSA's present theme issue on aspects of HIV epidemiology in Africa. The focus on recent empiric data, rather than on modelling or speculation, no longer leaves reasonable doubt that sexual behaviours are insufficient to explain 'Why Africa?' It is fitting that this progress was encouraged, from beginning to end, by long-time, and now departing IJSA Editor-in-Chief, Dr Wallace Dinsmore.

Political determinants of variable aetiology resonance: explaining the African AIDS epidemics

Notwithstanding the massive social and economic disruptions caused by HIV/AIDS in many sub-Saharan countries, the epidemic does not pose a serious political threat to African governments. Based on an analysis of today's dominant aetiologic framing of HIV/AIDS in sub-Saharan Africa, this paper argues that the behaviour-centred explanatory approach contributes to the political domestication of the epidemic. The behavioural aetiology suffers from a double reductionism: It concentrates on sexual transmission only and, within sexual transmission, it focuses exclusively on the immediate cause of transmission (unprotected sex), omitting that biological co-factors increase populations' vulnerability to infection. By overlooking these non-behaviour-related determinants of sexual HIV transmission, this explanatory approach implicitly blames individual behaviours for the spread of the virus. Conversely, the likely underestimation (if not the outright denial) of iatrogenic HIV transmission exonerates governments and donor agencies. The variable political resonance of different explanatory approaches is not random and the translation of the available bio-medical and epidemiological evidence into prevention measures is politically mediated.

Injection drug use, unsafe medical injections, and HIV in Africa: a systematic review

The reuse of injecting equipment in clinical settings is well documented in Africa and appears to play a substantial role in generalized HIV epidemics. The U.S. and the WHO have begun to support large scale injection safety interventions, increased professional education and training programs, and the development and wider dissemination of infection control guidelines. Several African governments have also taken steps to control injecting equipment, including banning syringes that can be reused.However injection drug use (IDU), of heroin and stimulants, is a growing risk factor for acquiring HIV in the region. IDU is increasingly common among young adults in sub-Saharan Africa and is associated with high risk sex, thus linking IDU to the already well established and concentrated generalized HIV epidemics in the region. Demand reduction programs based on effective substance use education and drug treatment services are very limited, and imprisonment is more common than access to drug treatment services.Drug policies are still very punitive and there is widespread misunderstanding of and hostility to harm reduction programs e.g. needle exchange programs are almost non-existent in the region. Among injection drug users and among drug treatment patients in Africa, knowledge that needle sharing and syringe reuse transmit HIV is still very limited, in contrast with the more successfully instilled knowledge that HIV is transmitted sexually. These new injection risks will take on increased epidemiological significance over the coming decade and will require much more attention by African nations to the range of effective harm reduction tools now available in Europe, Asia, and North America.
