D. Ebola
Read Explanation:
Depending on the exact context or time period you are looking at, your statement most likely refers to one of the following landmark World Health Organization (WHO) declarations:
1. Polio Outbreaks (August 2026)
The WHO officially declared the end of polio outbreaks in five African nations, including the West African countries of Ghana and Guinea-Bissau. Following exhaustive Independent Outbreak Response Assessment (OBRA) field reviews, it was concluded that localized poliovirus transmission had been successfully stopped in these territories.
2. River Blindness Elimination (Early 2026)
The WHO verified that Niger became the first country on the African continent to completely eliminate River Blindness (onchocerciasis).
3. The Historic Ebola Epidemic (2016)
If your question is a textbook or competitive exam reference regarding a major regional epidemic, it refers to Ebola. The WHO famously announced that all known chains of Ebola virus transmission had been halted in West Africa (specifically across Guinea, Liberia, and Sierra Leone), bringing a formal close to the most lethal Ebola epidemic in human history.
