HIV patient testing falls in SA after US aid cuts, data shows

Testing and monitoring of HIV patients across SA have fallen since the US cut aid that funded health workers and clinics, with pregnant women, infants and youth the most affected, previously unpublished government data shows.
SA has the world's highest burden of HIV, with about 8-million people, or one in five adults, living with the virus. The US was funding 17% of the country's HIV budget until President Donald Trump slashed aid earlier this year.
Data from the National Health Laboratory Service, a government entity, showed viral load testing fell by up to 21% among key groups in the past two months, which four HIV experts said appeared to be due to the loss of US funding.
Viral load testing measures how much virus is in the blood of people living with HIV who are on antiretroviral treatment. It is normally done at least once a year.
It checks whether the treatment is working and whether the virus is sufficiently suppressed to prevent it spreading to others.
With less testing, fewer people who may transmit the virus will be identified. Missing a test can also indicate a patient has dropped out of the system and may be missing treatment.
It is specially important for pregnant women who may be at risk of transmitting HIV through childbirth, and for infants who need to be diagnosed and treated early to survive.
Trump froze many foreign aid programmes early in his presidency, before reinstating some lifesaving assistance, including parts of the US President's Emergency Plan for Aids Relief (Pepfar), its global HIV initiative. But SA was also specifically targeted, with an executive order cutting all funding to the country in February.
SA did not rely on US funding for its HIV drugs, but about 15,000 health workers' salaries were paid by Pepfar, which previously gave SA more than $400m (R7.2bn) a year. Most of the funding has been withdrawn, though it is unclear exactly how much.
The health workers did HIV testing and counselling in districts with a high prevalence of HIV, and followed up when patients missed a check-up or dropped off treatment, which is common.
The Pepfar funding also supported NGO-run clinics which have closed. The government has urged HIV patients who did check-ups at the clinics to go to public health centres instead, but public health centres often have long lines and staff can be unwelcoming to certain groups such as sex workers and gay men.
According to the data seen by Reuters, the number of viral load tests conducted for people aged 15 to 24 fell by 17.2% in April compared to April last year, after dropping 7.8% year-on-year in March. Total population testing was down 11.4% in April.
Maternal viral load testing was down 21.3% in April after falling by 9.1% in March, and early infant diagnostic testing was down 19.9% in April after falling by 12.4% in March, the same data showed.
The percentage of people who were virally suppressed among those tested also fell nationwide by 3.4% in March and 0.2% in April, with steeper declines for young adults, a further sign patients may have had their treatment interrupted, the data showed.
The data has not been made public.
'These are shocking figures, with profound implications for maternal and child health across the country,' said Francois Venter, executive director of the Ezintsha Research Centre in Johannesburg.
Given a summary of the data, Foster Mohale, a spokesperson for the department of health, said more analysis was needed and SA had challenges with patient retention and viral load testing before the aid cuts.
HIV experts have said for months the health ministry was downplaying the impact of the funding loss, and a drop in testing figures might be an early warning sign, followed by a rise in new cases and deaths.
The US state department did not immediately respond to a request for comment.
'This data demonstrates what previous models have shown regarding the impact of Pepfar/USAID cuts on pregnant women and their infants,' said Dvora Joseph Davey, an epidemiologist working on maternal and infant HIV at the University of Cape Town.
She said the impact was clear at five public health clinics where she works in Cape Town, which since the US aid cuts have been under-staffed, with fewer nurses to draw blood needed for viral load tests.
HIV experts said diagnostic testing was also likely affected by the funding cuts, though that data was not available.
The counsellors who used to do rapid diagnostic HIV tests are also gone, and pregnant women are no longer being put on preventive HIV drugs (PrEP) because the counsellors are the ones who used to offer that, Davey said.
In the Johannesburg township of Diepsloot, HIV activist and community leader Sophy Moatshe said it was hard to get HIV patients to seek care because of the stigma, and without health workers reaching out when they miss an appointment, many fall through the cracks.
'These people, they don't want to go to the clinic,' she said outside a community centre.
'If there is nobody to check them, they're going to die.'
The long-term future of HIV-related US assistance remains uncertain in SA and globally, as Trump pursues cuts to the international aid budget in line with his 'America First' agenda.
The cuts have also hit research, including HIV vaccine trials.
Mohale said the government was speaking to prospective local and international donors about covering funding gaps, but declined to give details.
Davey said the data on testing in April, however, was 'a good indication of what's going to happen in the future'.

When lies Trump truth — debunking the migrant myth in South Africa's healthcare crisis
Blaming migrants for South Africa's ailing healthcare system is a dangerous and politically convenient fiction. Despite mounting evidence to the contrary, this narrative persists, deflecting attention from the real source of collapse: State failure. There is no question that South Africa's public health system is in crisis. Healthcare professionals, policy analysts and political parties highlight systemic dysfunction, characterised by chronic underfunding, collapsing infrastructure, staff shortages and weak governance. ActionSA itself has admitted that Gauteng's health crisis stems from ' inadequate project management, lack of accountability and consequence management, coupled with a lack of skilled personnel and inefficient supply chain processes '. Few would dispute that the state, across all spheres, has failed to deliver quality, accessible healthcare to all. Yet, the claims that foreign nationals are 'overburdening' hospitals or 'abusing' the system continue to dominate the discourse. So widespread is this scapegoating that it has taken on the illusion of truth. But there is no credible evidence to support such claims. On the contrary, multiple studies, including government-commissioned reports, show that many migrants – especially those who are undocumented – actively avoid healthcare facilities due to fear of arrest, discrimination and outright denial of care. When they do seek help, many pay out of pocket, often at higher rates than South African citizens. Scapegoating is not a solution. It's a distraction – and not a new one. There is a deep irony in a nation forged through the struggle against racial oppression now deploying the same exclusionary logic against 'outsiders'. The parallels with Trump-era politics are disturbing. Just as the US president weaponised the myth of white victimhood to slash aid to South Africa and promote a whites-only refugee policy, local politicians have embraced the same playbook – fear-driven, fact-free and designed to divide. Figures like Gayton McKenzie and Herman Mashaba, and movements such as Operation Dudula have built platforms on xenophobic conspiracy theories, and revived colonial-era stereotypes. Their messages, amplified through social media, reach millions, spreading fear and misinformation. Trump would be proud. We may not be exporting white refugees, but we are certainly importing white nationalist logic. 'How can we improve access to quality healthcare?' asks ActionSA. Well, take a look: they don't know. Their solution? ActionSA asserts: ' No South African can enter another country legally without providing proof of medical insurance.' This statement isn't just factually flawed, it reveals a fundamental misunderstanding of both international mobility and health equity. Many South Africans can and do travel without medical insurance, and many countries do not require it for entry. But more importantly, health access should not be framed as a zero-sum, transactional privilege – it is a human right Debunking the 'healthcare rescue' myth South Africa's healthcare system is not collapsing under the weight of so-called medical tourism. It is crumbling under decades of budget cuts, poor planning and political neglect. The South African Human Rights Commission has warned that denying foreign nationals access will not alleviate pressure on the system. The government's own data shows that migrants constitute just 4% of South Africa's population. They are not responsible for drug shortages, collapsing infrastructure or staff vacancies. Yet, the fearmongering has deeply distorted public perception. The Human Sciences Research Council's South African Social Attitudes Survey found that most South Africans believe there are more than 25 million foreign nationals in the country, with more than 20 million assumed to be 'illegal'. This is not just incorrect, it is the result of sustained political misinformation. Until evidence replaces ideology, this 'alternative truth' will continue to thrive – and 'trump' truth. Scapegoating isn't policy, structural reform is South Africa's crises – whether in healthcare, housing or public safety – are not demographic pressures. They are the result of structural failures. Blaming the marginalised is easier than confronting the uncomfortable truths about misgovernance. In provinces like the Eastern Cape per capita health spending has declined even as patient numbers continue to grow. Experts have consistently pointed to institutional neglect, not migrants, as the root cause. The Life Esidimeni tragedy, in which 144 mental health patients died due to state negligence, had nothing to do with foreign nationals. And yet the migrant 'burden' myth endures – because it serves a purpose: it redirects public anger away from those in power and towards those with the least power. We must hold all political rhetoric to the same standard. Just as we rightly demand evidence when Trump claims white victimhood, we must also demand it when Mashaba, McKenzie or Dudula blame migrants for systemic failures. We cannot selectively suspend our commitment to truth. The real crisis is not migration. It is misgovernance. And the sooner we name it, the sooner we can begin to rebuild what has been broken.

WHO recommends Gilead's twice-yearly injection lenacapavir for HIV prevention
The World Health Organisation (WHO) on Monday recommended Gilead's lenacapavir, a twice-yearly injection, as a tool to prevent HIV infection. The recommendation, issued at the International Aids Conference in Kigali, Rwanda, comes nearly a month after the US health regulator approved the drug, giving patients new hope of interrupting virus transmission. The twice-yearly injectable offers a long-acting alternative to daily oral pills and other shorter-acting options, reshaping the response to the disease especially among those who face challenges with daily adherence, stigma or access to healthcare. 'While an HIV vaccine remains elusive, lenacapavir is the next best thing,' said WHO director-general Tedros Adhanom Ghebreyesus. The WHO's recommendations come at a critical moment as HIV prevention efforts stagnate with 1.3-million new HIV infections in 2024 as funding challenges and stigma about the disease persist.
