Madagascar has taken a decisive step in protecting public health by officially closing the outbreak of type 1 poliovirus that had affected the country since 2020. After recording 287 cases—including 45 with acute flaccid paralysis and 198 positive detections in wastewater—the country has met the WHO’s international standards: more than 12 months without new cases and a robust surveillance system confirming the interruption of transmission.

This success is the result of a comprehensive response led by the Malagasy government and supported by international organizations such as WHO, UNICEF, GAVI, Rotary, and the Gates Foundation. In 2023, four mass vaccination campaigns were carried out, reaching 95% of the target population. Authorities implemented innovative strategies such as door-to-door immunization, expanded environmental surveillance, and intense community mobilization.
Coordination was led by the Emergency Operations Center with high-level political support. “Polio is finally eradicated in Madagascar. Together, we have proven that lasting change is possible,” said First Lady Mialy Rajoelina, the country’s immunization ambassador.
Beyond controlling the outbreak, the country has strengthened its health system. Madagascar’s model demonstrates that the combination of political will, strategic partnerships, and community involvement can halt preventable diseases. Today, Madagascar stands as a beacon of health resilience in Africa.
Health authorities continue working to maintain routine immunization, enhance preparedness for future outbreaks, and ensure no child is left unprotected. The end of this outbreak is not only a medical victory but also a sustained commitment to the right to health for future generations.
