Heat Health Early Warning Systems — Country Web Search Results
Search Methodology
Targeted web searches conducted March 2026 using English, French, and Portuguese queries. Sources prioritised: WHO AFRO/SEARO publications > Ministry of Health/National Meteorological Agency documents > peer-reviewed papers > NGO/World Bank reports > credible news of specific government responses. Evidence of a HHEWS requires: a named heat action plan with alert thresholds, a government response protocol linked to temperature, operational heat surveillance, or a digital/SMS alert system for extreme heat. General climate adaptation plans mentioning heat in passing do not qualify.
Key background reference: Thiaw et al. (2022), “Toward Experimental Heat–Health Early Warning in Africa,” Bulletin of the American Meteorological Society — establishes that Africa, especially the Sahel, has a major gap in heat-wave monitoring and forecasting, and that heatwave forecasts are reliable ≥8 days in advance, making HHEWS feasible across the region.

Summary
No evidence was found of an operational heat-health early warning system in Rwanda. The country has taken early steps toward climate-health integration: in 2024, Rwanda’s Ministry of Health established a Climate Change and Health Technical Working Group to coordinate multisectoral efforts. Meteo Rwanda provides weather and early warning services primarily for agriculture and disaster management, but no heat-specific health protocols or thresholds have been publicly documented. The gap is consistent with the broader finding from Thiaw et al. (2022) that sub-Saharan African countries outside West Africa’s Sahel have limited heat-health EWS capacity.

Summary
Uganda launched Africa’s first Health National Adaptation Plan (H-NAP) in August 2024, a significant milestone. However, the H-NAP currently lacks climate-triggered heat surveillance systems. Current gaps include missing ministerial coordination mechanisms, undefined heat-specific health targets, and no operational HHEWS. Uganda is a DHIS2 pilot country for the Climate & Health project, which may provide a pathway for integrating heat surveillance into existing HMIS infrastructure. No heat action plan or temperature-threshold-based alert system was found in public documents.

Summary
Ethiopia is the most advanced of the English-speaking African countries reviewed. The Ethiopian Public Health Institute, with WHO support, has established EWARS sentinel sites across multiple climatic zones since 2017, integrating climate and health data. A Climate and Health Working Group coordinates between the Federal Ministry of Health and the National Meteorological Services Agency. While EWARS focuses primarily on vector-borne and climate-sensitive diseases, heat stress is included as a tracked hazard in the H-NAP II. The system represents a meaningful foundation for a dedicated HHEWS, though no standalone heat action plan was found.

Summary
Nigeria faces an acute and growing heat crisis — over 60% of the population is regularly exposed to dangerous heat indices, and heat-related illness increased by 30% between 2023 and 2024 with over 2,000 deaths attributed to extreme heat. The Nigerian Meteorological Agency (NiMet) issues heat forecast warnings, and the Nigeria Medical Association has disseminated public health messaging. However, no formal national heat action plan or operational HHEWS has been established. A 2025 academic paper outlines a roadmap for a Nigerian heat health plan, and the TECA Heat Action Wave initiative (2025) is funding innovative early warning tools. Nigeria is at an early but active stage.

Summary
No evidence of an operational HHEWS or heat action plan in Ghana was found. A 2025 study identifies significant heat-health risk — particularly for outdoor workers in farming, construction, and fishing — and explicitly calls for Ghana Health Service to develop heat early warning systems with time-specific advisories. The Ghana Meteorological Agency has not published heat-health specific thresholds or alert protocols in publicly accessible sources. Ghana is notably absent from regional HHEWS development initiatives documented in the literature, representing a clear gap for a country with a large agricultural workforce.

Summary
Malawi has made substantive progress. Through the “Adaptation for Africa” project (supported by GFCS/WHO from 2014), Malawi developed a Health National Adaptation Plan, a climate communication strategy, and public health advisories for extreme weather events including heatwaves — translated into local languages and field-tested. The Ministry of Health also enhanced EWARS capacity in four districts for predicting vector-borne disease outbreaks, which integrates climate data. As a DHIS2 pilot country, Malawi has an active pathway for integrating heat data into its HMIS. This is one of the stronger cases among the reviewed countries, though a standalone heat action plan with temperature thresholds was not confirmed.

Summary
Tanzania is among the most active countries reviewed. Under WHO’s “Beat the Heat” initiative (January 2025–June 2026), Tanzania is developing national heat-health action plans, deploying early warning systems and emergency heat protocols, and training health responders and event organisers. The initiative is led by the Ministries of Health in Mainland and Zanzibar in collaboration with Tanzania Meteorological Services and the Emergency Department at Muhimbili National Hospital. Tanzania is one of the first countries globally to roll out this initiative. As a DHIS2 pilot country, integration with existing HMIS infrastructure is feasible.

Summary
No operational HHEWS or heat action plan exists in Mozambique. Research on heatwaves is described as “pioneering” with local characteristics and impacts largely unknown, and recognition of extreme heat as a public health threat remains absent from government policy. Mozambique is nonetheless a DHIS2 country with documented integration of climate data into its HMIS, which creates a platform for future development. The Portuguese-language search did not surface any MISAU (Ministry of Health) communications on heat specifically. Mozambique represents a significant gap given its high climate vulnerability and cyclone/heat exposure.

Summary
Only 4 sources were identified — absence of evidence is itself a finding. No HHEWS, heat action plan, or government heat-health protocol was found for Guinea-Bissau in either English or Portuguese. The country faces genuine and worsening heat risk (temperatures exceed 40°C in peak months, with a documented upward trend since 1981), but institutional capacity for heat-health response is extremely limited. As a small, fragile state, Guinea-Bissau likely lacks the meteorological and public health infrastructure for an independent HHEWS and would need significant external support.

Summary
No country-specific HHEWS or heat action plan for Niger was found. However, Niger is uniquely positioned through AGRHYMET — the regional hydrometeorological centre headquartered in Niamey — which now leads a Regional Watch Room providing real-time climate risk intelligence across West Africa. Niger’s meteorological services have participated in NOAA heat wave training. The Sahel’s acute and worsening heat burden (exacerbated by the April 2024 Ramadan heatwave) creates strong urgency. A national HHEWS in Niger could leverage AGRHYMET’s regional forecasting capacity, with the MoH as the health-sector counterpart — but no such linkage is currently documented.

Senegal is the most advanced country in this review — the only one with a documented, operational HHEWS. Since 2022, ANACIM (National Agency of Civil Aviation and Meteorology) and the Ministry of Health’s Directorate General of Public Health (DGSP) have co-produced weekly heatwave bulletins during peak season (March–June), with 35 bulletins issued by the time of case study publication. The system provides 1–3 week predictive forecasts with colour-coded zone maps and targeted health guidance. In the Fatick pilot, medical staff and emergency workers were better prepared for increased patient load and could more effectively reach vulnerable populations. Senegal provides the clearest model for other DHIS2 countries to adapt.

Summary
No formal HHEWS or heat action plan for Togo was found. Public health messaging on heatwaves exists (via the Santé-Education Togo platform), and WHO advisors have engaged on heat risk communications. Togo’s northern regions experience extreme heat (40°C+), classified as high risk by ThinkHazard. Neighbouring Burkina Faso is actively developing a heat preparedness plan, which could serve as a model. As a DHIS2 expanding country (joining 2026), Togo has a near-term opportunity to develop heat surveillance integrated with its HMIS, though institutional capacity would need strengthening.

Summary
No heat-specific HHEWS was found for DRC. The country launched the “Early Warnings for All” (EW4All) initiative in January 2026, which covers a broad range of climate hazards including heat, and is actively strengthening its hydrometeorological agency (MettelSat) through CREWS and World Bank support. These represent important foundational investments. DRC’s extreme heat hazard is classified as medium, lower than Sahel countries, which may explain the lower priority given to heat specifically. As a 2026 DHIS2 expanding country, DRC will have a new institutional pathway for integrating climate data into its HMIS.

Nepal has the most developed subnational HHEWS among the Asian countries reviewed. DHM issues heat and cold wave bulletins and has deployed real-time LED displays in cities. City-level heat action plans exist for Nepalgunj (2023) and Dhangadhi (2025), developed with Red Cross support; additional cities are in progress. The Ministry of Health prepared a comprehensive H-NAP in 2024 including heat wave response protocols and healthcare facility readiness standards (cooling blankets, IV fluids, air conditioning). Gaps remain at the national level — the Mercy Corps 2025 policy brief calls for a national HHEWS coordinating local-level plans. Nepal offers a strong model for subnational approaches.

Summary
Laos does not have a heat action plan and lacks a dedicated HHEWS, despite experiencing record-breaking temperatures in 2023. WHO Lao PDR is actively supporting development of a climate-sensitive disease EWS integrated with the HMIS, but this is still in development and is not heat-specific. As a DHIS2 pilot country for climate-health, Laos has a foundational platform for integration. The combination of rapidly rising temperatures, a large agricultural workforce, and an existing DHIS2 health data system makes Laos a strong candidate for a targeted HHEWS pilot.

Key patterns
- Senegal is the clear regional model — its ANACIM/MoH partnership and bulletin system is the only fully operational HHEWS among the countries reviewed. It should anchor any advocacy or replication work.
- Tanzania and Nepal are the most actionable near-term opportunities — both have active HHEWS development under way and are DHIS2 pilot countries.
- Africa is underserved relative to risk — Sahel countries (Niger, Togo, Guinea Bissau) face some of the world’s highest heat exposure but have the least institutional HHEWS capacity.
- DHIS2 pilot countries have a structural advantage — Malawi, Ethiopia, Tanzania, Nepal, Sri Lanka, and Laos all have active DHIS2 climate-health work, creating a ready pathway for integrating heat surveillance into existing HMIS infrastructure.
- The met-health agency gap is the central barrier — in all countries without an operational HHEWS, the absence of a formal collaboration mechanism between the national meteorological agency and the Ministry of Health is the common bottleneck. Senegal’s ANACIM/DGSP model directly addresses this.
- Absence of evidence is significant for Guinea Bissau and Mozambique — despite real heat risk, these countries have virtually no publicly documented heat-health governance, suggesting they need capacity-building before HHEWS development is feasible.
