Rio de Janeiro, Brazil — Proof is rising that the individuals most affected by HIV are additionally probably the most weak to the consequences of local weather change.
Local weather change is reshaping well being programs and lives throughout the globe, however its affect on the HIV response has acquired far much less consideration than it deserves. Floods, droughts and displacement are fragmenting testing, counselling and prevention programmes, and damaging the infrastructure that retains individuals in care. In areas comparable to sub-Saharan Africa, the place poverty and structural inequality already drive a disproportionate share of the worldwide HIV burden, these shocks danger pushing probably the most weak additional behind.
Though local weather change doesn’t alter how HIV behaves within the physique, it’s more and more influencing who turns into contaminated with HIV, who stays in care and, finally, who survives. As excessive climate occasions grow to be extra frequent and extreme, well being consultants warn that many years of progress towards HIV could possibly be undermined until local weather resilience turns into central to HIV programming.
For Abireham Misganaw, the World Local weather and Well being Technical Lead at Pathfinder Worldwide, the convergence of the local weather disaster and the HIV epidemic is not a future concern; it’s already unfolding throughout lots of the world’s most weak communities.

“Local weather change is more and more disrupting the HIV response by damaging well being programs, displacing communities, worsening meals insecurity, and making it more durable for individuals to succeed in companies,” he mentioned. “Proof reveals that excessive climate occasions can have an effect on the complete HIV care continuum, together with testing, linkage to therapy, viral suppression and prevention companies.
Misganaw mentioned that climate-related disasters harm well being services, disrupt transport networks, displace communities and worsen meals insecurity, making it more and more troublesome for individuals dwelling with HIV to entry important companies. Missed clinic appointments, interrupted therapy and decreased entry to prevention programmes can rapidly reverse hard-won beneficial properties in HIV management.
Pathfinder has noticed these dangers firsthand in Mozambique, mentioned Misganaw, the place a succession of cyclones – Idai and Kenneth in 2019, Gombe in 2022, and Freddy in 2023 – broken well being services and disrupted group outreach and HIV service supply in a number of provinces. The organisation labored alongside native well being authorities to revive companies by strengthening group well being employee networks, integrating HIV care into major healthcare and enhancing follow-up for weak populations.
He mentioned these experiences reveal why local weather resilience ought to not be seen as a separate environmental difficulty however should now be constructed into HIV applications.
Damaged therapy
Excessive climate can be exposing long-standing weaknesses in well being programs, significantly medication provide chains. Floods, droughts and different excessive climate occasions do not simply shut clinics. They interrupt antiretroviral remedy by damaging services, blocking transport routes, displacing sufferers and employees, and disrupting the availability chains that hold medicines flowing.
“The implications embody therapy interruption, poor adherence, disengagement from care, elevated viral load, and a better danger of AIDS-related sickness and dying,” mentioned Dr Joram Sunguti Luke, a medical physician and public well being skilled who works in HIV and AIDS & Sexual and Reproductive Well being and Rights (SRHR), and is Senior Technical Advisor at Pathfinder Worldwide.
“These shocks additionally make it more durable to succeed in individuals with prevention, counselling, and follow-up companies on the very second they could want them most,” he mentioned.
In keeping with Dr Sunguti, Pathfinder affords a strategic mixture of behavioural, biomedical, and structural HIV prevention interventions tailor-made to native contexts and the wants of various populations. These populations embody adolescent ladies and younger ladies, high-risk boys and younger males, key populations, individuals in HIV serodiscordant relationships, and people inside jail settings. Group-based approaches, together with cell clinics, peer navigators, group ART teams and residential supply of medicines, can considerably scale back therapy interruptions throughout local weather emergencies.
Local weather change can be exposing the fragility of drugs provide chains that thousands and thousands of individuals dwelling with HIV rely upon.
Dr Sunguti mentioned that local weather change highlights the significance of climate-smart provide chains able to sustaining medication availability throughout floods, excessive warmth and infrastructure failures. “The largest provide chain weaknesses are weak forecasting and quantification, restricted buffer shares, fragmented procurement programs, poor last-mile supply, insufficient storage, and low resilience to move and energy disruptions that have an effect on the chilly chain,” he mentioned.
Local weather shocks expose these vulnerabilities nearly immediately, significantly the place warehouses, roads and digital programs had been by no means designed to resist floods, storms or warmth. The fixes are equally properly understood: stronger logistics knowledge programs, decentralised distribution, multi-month dishing out, emergency inventory buffers, climate-resilient storage, and contingency plans examined properly earlier than a disaster hits.
To strengthen resilience, Dr Sunguti mentioned international locations want higher logistics knowledge programs, decentralised medication distribution, multi-month dishing out of antiretroviral medicines, emergency inventory buffers, climate-resilient storage services and contingency plans which can be examined earlier than disasters strike.
He mentioned the organisation has applied HIV prevention, care and therapy programmes throughout 10 international locations utilizing evidence-based, rights-based and gender-responsive approaches. Its present work focuses on integrating HIV companies into major healthcare whereas strengthening group and well being programs. That has included supporting ministries of well being in strengthening provide chain administration via improved forecasting, logistics administration info programs (LMIS), knowledge use for decision-making, and decentralized distribution programs built-in inside major healthcare.
Who will get left behind
Local weather change just isn’t affecting everybody equally. Dr Sunguti mentioned probably the most at-risk teams are individuals dwelling in poverty, ladies and ladies, adolescents and younger individuals, rural communities, migrants and displaced individuals, individuals with disabilities, and key populations who already face stigma and boundaries to care.
Adolescent ladies and younger ladies are significantly uncovered, as a result of climate-related poverty can drive up college dropout, transactional intercourse, little one marriage and gender-based violence, all recognised drivers of HIV an infection. These teams usually have the fewest assets to soak up the shock of transport disruption, revenue loss, meals insecurity or service closures. Which means that local weather shocks, due to this fact, deepen current inequalities until responses are intentionally designed to succeed in these most probably to be missed.
Displacement compounds the issue additional, severing the hyperlink between individuals and the companies they rely upon. “When communities are displaced, or roads and clinics are broken, HIV testing, counselling, condom distribution, PrEP supply, and peer-led outreach are sometimes the primary companies to be interrupted,” he mentioned.
“Local weather shocks expose weaknesses in well being programs and medication provide chains.”
Following Cyclone Idai in Mozambique, for instance, large-scale displacement sophisticated HIV testing, therapy continuity and affected person monitoring as a result of many people misplaced entry to their ordinary well being services and medical information, he mentioned. Folks additionally misplaced medical information, miss appointments, or keep away from companies due to stigma, insecurity, or uncertainty about the place to go.
“That’s the reason emergency responses ought to embody HIV continuity planning, not solely short-term aid,” mentioned Dr Sunguti.
Sub-Saharan Africa’s disproportionate share of the worldwide HIV burden can’t be separated from poverty, and that has direct implications for the way prevention is designed. Poverty discount ought to be handled as a core a part of HIV prevention, particularly in high-burden areas the place local weather shocks, meals insecurity and financial stress work together with HIV danger.
“When households face starvation, misplaced revenue or unstable livelihoods, persons are extra more likely to face boundaries to prevention and therapy, and in some contexts could also be pushed towards higher-risk coping methods,” he mentioned.
Social safety, livelihoods assist, meals help and money transfers are due to this fact not peripheral add-ons. They perform as prevention-enabling interventions in their very own proper. They need to be seen as investments in HIV prevention as a result of they scale back the financial pressures that may improve vulnerability.
Regardless of the rising challenges posed by local weather change, scientific advances are additionally creating new alternatives.
Scientific advances are opening a brand new entrance on this combat. Dr Sunguti mentioned that the long-acting HIV instruments have the potential to make care extra resilient by lowering how usually individuals want to go to clinics and by enhancing continuity in periods of disruption. The PURPOSE 1 and PURPOSE 2 scientific trials discovered that twice-yearly lenacapavir supplies near-complete safety towards HIV acquisition amongst ladies and different at-risk populations, probably the most vital advances in HIV prevention in many years.
“Lengthy-acting prevention merchandise could possibly be significantly priceless in climate-vulnerable settings as a result of fewer clinic visits scale back dependence on transport infrastructure that could be disrupted by floods or excessive climate,” he mentioned.
For prevention particularly, longer-acting choices might help shield individuals who wrestle with day by day or frequent service entry, particularly throughout local weather shocks or displacement. They don’t seem to be a whole answer on their very own, he mentioned, however paired with equitable supply programs, community-based entry and dependable provide chains, they may meaningfully scale back vulnerability to interruptions.
The entry hole
The barrier to scaling instruments like lenacapavir is not scientific; it is financial and logistical. Scientific breakthroughs solely enhance public well being when international locations can truly afford to obtain and ship them. Excessive costs, licensing restrictions, restricted manufacturing capability, regulatory delays, and inadequate financing proceed to forestall many low- and middle-income international locations from accessing new HIV medicines.

The problem is not scientific innovation; it’s equitable entry.
Dr Sunguti known as for stronger collaboration between African governments, donors, pharmaceutical corporations, and international financing establishments to work collectively to speed up regulatory approvals, assist native manufacturing, develop voluntary licensing, and strengthen pooled procurement mechanisms via regional our bodies such because the Africa CDC and the African Medicines Company. Meaning voluntary licensing, he added, clear pricing, expertise switch, sooner regulatory approval, and pooled procurement in order that international locations can introduce new merchandise at scale and directly.
“Local weather change is not a future environmental concern; it’s an instantaneous menace to HIV epidemic management,” mentioned Dr Sunguti. “Each flood, drought, cyclone, or heatwave has the potential to interrupt prevention companies, disrupt therapy, weaken provide chains, and widen current well being inequities. Defending many years of progress towards HIV requires climate-resilient well being programs that may proceed delivering companies earlier than, throughout and after local weather shocks…”
“Local weather adaptation ought to due to this fact grow to be a core element of HIV programming quite than an add-on,” he mentioned.
Dr Sunguti mentioned that as delegates collect beneath the theme “Rethink. Rebuild. Rise,” AIDS 2026 ought to firmly place climate-resilient HIV programs on the centre of the worldwide agenda. “Local weather change is more and more disrupting HIV prevention, therapy, and care via displacement, excessive climate occasions, provide chain interruptions, and rising well being inequities, significantly in low and middle-income international locations,” he mentioned.
He added that the worldwide HIV response should transfer past adaptation to deliberately designing built-in, resilient well being programs that safeguard uninterrupted HIV companies whereas addressing the broader sexual and reproductive well being wants of climate-affected communities. Dr Sunguti mentioned that this requires higher funding in climate-smart major healthcare, community-led responses, digital improvements, and evidence-based insurance policies that guarantee probably the most weak populations aren’t left behind as local weather dangers proceed to accentuate.
