Keeping Malaria Out: Laos’ next test for success

Laos is quietly making one of public health’s most extraordinary success stories. Through sustained national leadership and tireless efforts of communities, frontline health workers, and partners, the country has driven malaria to the brink of elimination. Just over a decade ago, the country recorded a 15-year high of 50,674 indigenous malaria cases. By 2024, that figure had plunged to just 328 cases, a decline of more than 99 percent.
Yet malaria has not disappeared evenly. Today, the remaining burden is concentrated in just five southern provinces – Savannakhet, Salavan, Xekong, Champasak, and Attapeu, home to many upland minority communities, collectively known as Lao Theung. Among the Katang, Ta-Oi, Lavae, Alak, Nyaheung peoples, the risk of malaria remains present. A persistent effort is required in this final mile of elimination to reach remote communities and achieve zero indigenous transmission.
As World Malaria Day reminds us, the true test of success lies not only in reaching zero cases, but in ensuring malaria never returns. For Laos, now at historically low case numbers and on track for elimination by 2030, the challenge ahead is subtler, and complex.
A clear focus on preventing re-establishment (POR) – through continued vigilance, resilient health systems and sustained regional cooperation is essential. Under the leadership of the Department of Communicable Disease Control, Ministry of Health and alongside key partners, the Asia Pacific Leaders Malaria Alliance has collaborated to develop the Laos’ Sustainability and Transition Roadmap for Malaria 2025–2035, which places long-term endurance at the centre of the national response.
One of the most pressing challenges facing Laos is financial sustainability. Malaria programmes across the region have long relied on external assistance, particularly from global donors. That support has been transformative – but it will not last indefinitely. With donor financing for malaria anticipated to decline, Laos is keenly aware that transition planning for financial resources is no longer optional, but urgent. That makes establishing a cost sustainability and POR plan, an essential tool. Such an effort must clearly articulate funding needs across surveillance, diagnostics, treatment commodities and human resources. A POR plan provides tremendous return on investment. The costs of maintaining a minimum, well-functioning POR programme are dwarfed in comparison to the human, economic, and health system costs of responding to a future outbreak.
Equally critical is the question of technical capacity. As Laos enters the POR phase, malaria activities are increasingly integrated into broader health services.
Integration brings efficiencies, but carries risk. Concerns that low case numbers could inadvertently reduce technical focus are real. Without periodic refresher training and institutional memory, hard-won expertise can quietly erode. Health workers who no longer encounter malaria frequently may have lower awareness; losing proficiency in malaria response is a true risk. Ongoing capacity building for integrated health workers, targeted simulation exercises and clear standard operating procedures are vital to ensure that readiness is preserved.
The same principle holds true for commodities. Diagnostics, antimalarial medicines, and vector control tools remain essential during the POR phase, even if required in smaller quantities. At present, many of these commodities continue to be heavily donor-subsidised. Planning for sustained procurement – whether through pooled purchasing, national budget lines, or transitional financing mechanisms – must begin well before external support tapers off.
2026 is a decisive year for Laos. Under World Health Organization certification requirements, countries must maintain three consecutive years of zero indigenous cases before malaria-free status can be granted.
Continued political leadership and commitment will be key factors in ensuring the remarkable progress is transformed into lasting success. Sustained commitment – from across government, development partners and communities themselves – will be essential to lock in gains and prevent resurgence.
Regional cooperation will therefore remain equally crucial. Along the borders with Cambodia, Thailand and Vietnam, the next phase will also test how effectively Laos can coordinate across borders activities, pool surveillance and data and work with its neighbours to uphold mutual accountability. Making that coordination work in practice requires consistent convening and follow-through – an area where Laos’ leadership in regional platforms matters. By helping align priorities and keep attention on the border frontlines, Laos can signal that elimination is not only a national ambition, but a shared regional responsibility.
The story of malaria in Laos is already a remarkable one. It shows that with clarity of purpose and persistence, even entrenched public health challenges can be overcome. And the country serves as a beacon for much of Asia Pacific and indeed the world.
On this World Malaria Day, under the rallying call – Driven to End Malaria: Now We Can. Now We Must – the country is closer than ever to a malaria-free future. By placing prevention of re-establishment at the heart of national response and championing regional solidarity, Laos can ensure that malaria becomes a relic of its public health history.
