What part of the globe was officially declared free of wild polio on 25 August 2020?
Show answer Hide answer
Answer: A. Africa
Explanation
The World Health Organization officially declared the African region free of wild poliovirus on 25 August 2020. This monumental public health achievement followed decades of coordinated vaccination campaigns and grassroots mobilization. Selecting Africa accurately specifies the global continent that reached this historic disease eradication milestone. Wild poliovirus causes irreversible paralysis in children and historically affected hundreds of thousands of people annually. Eradicating a communicable disease requires achieving high vaccination coverage across diverse and sometimes inaccessible populations. International health agencies collaborate closely with local governments and volunteers to distribute oral polio vaccines.
Asia still contained localized reservoirs of wild poliovirus during the period when the African region was officially declared free. Afghanistan is a specific country within Asia rather than an entire global continent evaluated in this health declaration. The option of none of these is incorrect because Africa is the exact geographical region certified polio-free in 2020.
