Extreme Heat Reshapes Healthcare Delivery in Kano as Zimbabwe Rolls Out Long-Acting HIV Prevention
Rising temperatures in Kano are forcing healthcare workers to adapt working conditions while Zimbabwe launches twice-yearly HIV prevention injections with US support for 271,000 people.

Healthcare systems across Africa face mounting pressure from climate-driven heat stress and infectious disease burdens, with new developments highlighting both challenges and innovations in service delivery.
In Kano, Nigeria, extreme temperatures are fundamentally altering working conditions at health facilities, forcing medical staff to contend with heat that becomes punishing by mid-morning. The city's healthcare workers operate in environments where rising mercury affects both patient outcomes and staff capacity to deliver care. Murtala Muhammed Specialist Hospital, one of Kano's major referral centers, exemplifies facilities grappling with heat stress as temperatures climb throughout the day.
The heat impact extends beyond hospital walls. Construction workers like 32-year-old bricklayer Abubakar Umar face impossible choices between earning income and protecting health. "If I quit, I do not earn. But as I go on, I [suffer]," Umar told The Whistler, breaking from work to consume water from a plastic sachet under a fading umbrella. His experience reflects broader labor force vulnerabilities as climate change intensifies heat exposure across West Africa's urban centers.
Zimbabwe Launches Lenacapavir for HIV Prevention
Zimbabwe's Ministry of Health and Child Care officially launched Lenacapavir, a twice-yearly injectable HIV prevention medication, marking a significant shift in pre-exposure prophylaxis (PrEP) delivery. The rollout ceremony took place in Epworth, with Health Minister Douglas Mombeshora describing the launch as a milestone in efforts to reduce new HIV infections.
The United States government committed to supporting access to the long-acting injection for 271,000 Zimbabweans over the next three years, according to 263Chat. This represents a substantial expansion of HIV prevention options beyond daily oral PrEP tablets, addressing adherence challenges that have limited effectiveness of existing prevention methods.
Lenacapavir, developed by Gilead Sciences, requires administration only twice yearly compared to daily pill regimens. Clinical trials have demonstrated high efficacy rates, making the medication particularly valuable for populations struggling with daily medication adherence. Zimbabwe's adoption follows global efforts to expand access to long-acting HIV prevention tools, particularly in high-burden settings.
Climate and Health System Capacity
The Kano heat crisis underscores how climate change compounds existing health system vulnerabilities. Nigeria's northern states regularly experience temperatures exceeding 40 degrees Celsius during peak heat seasons, with projections indicating further increases. Healthcare facilities often lack adequate cooling infrastructure, affecting medication storage, equipment function, and staff performance.
Heat stress contributes to increased patient loads as dehydration, heat exhaustion, and heat stroke cases rise. Vulnerable populations including outdoor workers, pregnant women, and individuals with chronic conditions face elevated risks. The situation demands infrastructure investments and operational adaptations that many resource-constrained facilities cannot readily implement.
Meanwhile, Zimbabwe's Lenacapavir rollout demonstrates health system capacity to adopt innovative interventions despite economic constraints. The country maintains HIV prevalence of approximately 11.5 percent among adults aged 15-49, according to UNAIDS data, with prevention programs critical to epidemic control. US support through PEPFAR (President's Emergency Plan for AIDS Relief) enables access to newer prevention technologies that might otherwise remain financially out of reach.
Implementation Challenges and Forward Planning
Both situations highlight implementation complexities facing African health systems. In Kano, addressing heat impacts requires coordinated responses spanning infrastructure upgrades, occupational health protocols, and climate adaptation planning. Healthcare facilities need cooling systems, adequate water supplies, and modified work schedules to protect both patients and staff.
For Lenacapavir distribution, Zimbabwe must establish supply chains, train healthcare workers on administration protocols, and conduct community education to drive uptake. The twice-yearly dosing schedule offers advantages over daily pills but requires robust tracking systems to ensure patients return for scheduled injections. Cold chain requirements for the medication also demand reliable refrigeration infrastructure.
The 271,000-person target represents approximately 2.4 percent of Zimbabwe's adult population, suggesting initial focus on high-risk groups including adolescent girls, young women, and key populations. Scaling beyond this cohort will depend on demonstrated impact, continued donor support, and potential price reductions as generic versions become available.
Public health experts emphasize that climate adaptation and disease prevention programs require sustained investment and political commitment. As temperatures rise and infectious disease burdens persist, health systems need flexible, evidence-based approaches that address both immediate service delivery needs and longer-term structural challenges.
