Malaria and lymphatic filariasis (LF) are among the deadliest health threats that still remain in Papua New Guinea (PNG). In PNG, malaria transmission is largely concentrated in lowland and coastal areas, as is LF, while highland regions have historically experienced low malaria burden. However, climate change is reshaping this landscape, placing populations that were previously not at risk at increasing risk of malaria.

‍

PNG has demonstrated strong political commitment to eliminating both malaria and LF. Notably, His Excellency, former Prime Minister Peter O’Neill, committed to malaria elimination at the London Malaria Summit in 2018, where he endorsed the Asia Pacific Leaders' Malaria Elimination Roadmap, reaffirming commitment to the goal of an Asia Pacific free of malaria by 2030. However, significant constraints persist today, including limited resources at subnational levels, competing health priorities, and the lingering impacts of COVID‑19 which continue to impede the delivery of health programmes in PNG.

‍

Taken together, these realities point to the need for cross‑disease elimination strategies that are more integrated and cost‑effective, such as exploring joint vector control interventions for malaria and LF. Looking ahead, while sustained political commitment continues to provide a strong foundation for elimination, accelerating progress towards eliminating both malaria and LF in PNG will now also depend on scaling new evidence‑based tools, strengthening surveillance, and investing in capacity building to address the complexity of elimination efforts across diverse settings and multi‑disease strategies.
