Our HIV reporting of the past decade

< Back to special reports

A large chunk of our reporting focuses on HIV. Since the launch of Bhekisisa in 2013, we’ve covered HIV in-depth — from the impact of the virus on former president Nelson Mandela’s family to the advances in antiretroviral treatment and anti-HIV pills and injections. We’ve also looked at the impact of inequality and discrimination on the spread of HIV, the link between gender-based violence and HIV — and ways to fix it.

How rape survivors’ long-term risk of HIV infection can lead to heavier sentences for rapists

A new study shows that female rape survivors are 60% more likely to contract HIV within a year or two after their rape than women who have not been raped.

The results of a new study, that followed female rape survivors for up to three years, have finally given courts empirical evidence to use to prove that convicted rapists can — at least partly — be held responsible when women contract HIV for up to three years after their rape. 

The Rape Impact Cohort Evaluation (RICE) study found that female rape survivors between the ages of 16 and 40 were 60% more likely to contract HIV within a year or two after their rape than women who had not been raped, regardless of the HIV status of their rapist.

Reported rapes have consistently increased in South Africa between 2016/17 and 2019/2020, police statistics show. In the 2019/20 reporting year, 42 289 rapes were reported at police stations, but the actual number of incidents is almost certainly much higher — a 2012 community-based survey in Gauteng revealed that only one in 25 of women who were raped reported it to the police.

Rape survivors’ chances of getting their perperators convicted is, however, extremely low. A 2013 South African Medical Research Council (SAMRC) study found that less than one in ten rape cases opened by the police resulted in a guilty conviction. In fact, only 18.5% of such cases made it to trial and about half the time prosecutors wouldn’t prosecute a rape case referred to them if they believed it wouldn’t result in a conviction.

How the trauma of rape makes it harder to negotiate for safe sex

One of the recommendations of the RICE study, conducted by the SAMRC’s gender and health research unit, is that the long-term HIV-related “health burden associated with a rape experience” should be used “effectively in the justice processes” as aggravating evidence for sentencing. 

“Our study has shown that rape causes long-term health problems, such as an increased risk to acquire HIV for years after the rape,” says lead study author Naeemah Abrahams. “The immediate risk of infection after a rape, if the rapist was HIV-positive, is by no means the only HIV-related risk and prosecutors should be able to use the new evidence about the long-term infection risk to argue for heavier sentences for convicted rapists.”

Numerous studies have found that rape-related trauma, such as post traumatic stress disorder, anxiety, depression and self-blame can all massively compromise survivors’ ability to negotiate safer sex. If this type of trauma is left untreated, it can also lead to self-medication such as heavy drinking or drug use, which in turn, increases the chances of risky sexual behaviour. A 2007 study in the Journal of American College Health has, for instance, found that the less help an abused woman receives, the higher the likelihood that she’ll turn to alcohol to cope with her trauma and suffer further abuse.

The new evidence can help prosecutors to argue for heavier sentences for convicted rapists

But now there’s new evidence about the impact of rape on women’s long-term health, that could help prosecutors to argue for more severe sentences for convicted rapists.    

The National Prosecuting Authority’s sexual offence and community affairs unit has agreed to include the results of the RICE study in their advance training of prosecutors “to enhance their knowledge regarding the utilisation of this research in court for aggravating circumstances”, says the acting special director of public prosecutions, Pierre Smith. 

“One of the benefits of the findings of the RICE study is that it can be used to assist the court to arrive at a just sentence for a rape perpetrator,” he says. “It could, for instance, be used by the prosecution as an aggravating factor to argue that the court should impose the maximum sentence for a particular rape.”

A study on rape reveals that children are mostly raped on weekday afternoons, but adults over weekends. Our Mia Malan explains.

But such evidence, says Smith, would need to be presented to the court by an expert — as opposed to a prosecutor — as it’s based on research analysis. “That expert would need to be informed about the merits of the particular case in order to place the merits of the case in context with the findings of the study. This is essential to exclude misinterpretation or incorrect analysis findings of this particular research.” 

The RICE researchers followed just over 1 000 women from Durban — about half of them rape survivors and the other half not — for between one and three years between October 2014 and March 2020. The peer-reviewed study, which will be published in the journal AIDS in December/January, is the first to track such a large number of rape survivors for a long period — from within 20 days after their rape — and then compare their HIV status with that of a control group.  

Abrahams explains: “Not many other countries can do this type of study, because they don’t have the large numbers of both rape and HIV that we have in South Africa. That horrible situation — ironically — made this study possible.”

How the researchers found trial participants

The average age of participants in the RICE study was 23 years. This age group falls within the group of people in South Africa — teenage girls and young women between the ages of 15 and 24 — that is contracting HIV at the fastest rate by far. 

In some areas of the country, the HIV prevalence among adolescent girls and young women is up to six times higher than that of their male peers, according to UNAids. 

The RICE study researchers visited rape crisis centres to recruit rape survivor trial participants and primary healthcare clinics to enrol control group volunteers. All participants were tested for HIV at the start and then at every return visit, which was every three months in the first year and then every six months thereafter. 

The difference in HIV incidence (the rate of new infections), between the control and the rape survivor group started to show from the sixth month after enrollment; in other words, more or less six months after a rape had occurred.

Why the HIV prevention pill should be available to all teenage girls and young women

To decrease a rape survivor’s immediate chances of getting infected with HIV if the rapist was HIV-positive, South Africa started to provide post-exposure prophylaxis, or PEP, to rape survivors for free in the public sector in 2002. If people who have been raped take this 28-day long course of antiretroviral drugs within 72 hours of having been raped, the medicine dramatically reduces their likelihood of being infected. 

But the RICE study has shown that PEP isn’t enough.  

Because we now know there is a long-term risk of HIV infection, survivors also need to be prioritised for pre-exposure prophylaxis, or PrEP, the researchers argue. Studies have shown that PrEP, in the form of a daily pill, can reduce an HIV-negative person’s chances of getting infected with HIV by more than 90%, if taken correctly.  

Currently, South Africa’s PrEP guidelines don’t include rape survivors as a priority risk group to which the HIV prevention pill should be provided — but adolescent girls and young women in general are

The RICE study’s data, however, shows that the HIV incidence for both the control and rape survivor group is alarmingly high. So high, that all participants, by World Health Organisation (WHO) standards, qualify as populations at substantial risk of HIV infection that should be prioritised for PrEP

WHO guidelines recommend that PrEP should be a priority for populations with an HIV incidence of 3 per 100 person-years or higher.  

The HIV incidence of the RICE study’s survivor group was 6.6 per 100 person-years and for the control group it was 4.7 per 100 person-years. 

PrEP should therefore be a priority for all adolescent girls and young women in South Africa, says HIV researcher and clinical epidemiology professor at Columbia University, Quarraisha Abdool Karim. 

“The findings of the RICE study confirm the intertwining of the HIV and gender-based violence epidemics. Young women, especially those between 15 and 24, have a high chance of getting infected with HIV, but even more so if they had been raped.”

COVID-19 resulted in the health department falling behind with its PrEP targets

The health department, with help from the US government’s President’s Emergency Fund for Aids Relief, Pepfar, provides PrEP for free at 218 sites in South Africa, including at 39 schools, 13 universities and 11 technical and vocational education and training (TVET) colleges and 1135 public health facilities. 

Although the department exceeded its targets for PrEP distribution among adolescent girls and young women for 2019/2020, it fell behind with its goals this year (2020/21), because of the COVID-19 pandemic. By the end of August, only 17 748 out of the target of 41 105 girls and young women had been reached with the HIV prevention pill.  

“COVID-19 lockdowns limited movement and resulted in fewer people visiting public health facilities and other venues where PrEP is provided and that impacted heavily on how many people we could reach,” explains the health department’s director of HIV prevention, Thato Chidarikire. “But we’re picking up speed again — remember, this is a phased in approach, we’re only in the beginning stages of making PrEP more widely available in the public sector.”

Chidarikire says, based on the RICE study’s results, rape survivors will likely be added to the department’s PrEP guidelines as a risk group that should be prioritised for PrEP and the department will look into making the medication available at rape crisis centres. “It makes sense to invest resources into preventing HIV acquisition, because good prevention is better than treating HIV.”

Why we need long-acting forms of PrEP for teenage girls and young women

The HIV prevention pill needs to be taken once a day at more or less the same time to produce the best results. So, adherence to PrEP has often proven to be a problem to young women in studies. Researchers are therefore looking into forms of PrEP that can be taken less often.

In November, the results of the HPTN084 study, that tested whether a PrEP injection every eight weeks could prevent HIV infection in cisgender women, showed that the shot is even more effective than a daily pill.

But the jab, which contains the antiretroviral drug cabotegravir, is more expensive than a daily pill and has not yet been registered for use.

The Centre for the Aids Programme of Research in South Africa, Caprisa, where Abdool Karim is the associate scientific director, is also researching a long-acting form of PrEP for teenage girls in the form of a match-sized implant that could potentially be inserted in the upper arm once a year, but the study is still in its infancy.

Bhekisisa editor Mia Malan talks to HIV scientist Salim Abdool Karim about his research on risky relationships of young women and older men.

Ultimately, Abdool Karim says, we need to address the cause of HIV and rape: gender inequity. “Gender-based violence and HIV are not two independent epidemics, they are intertwined. Both are fuelled by gender inequity, which puts particularly young women on a very different trajectory from young men. Whether we look at gender-based violence or HIV, women are bearing the brunt.”
