Hint
Disease
Only human disease completely eradicated, in 1977. Caused by a virus and killed around 500 million people in the 100 years before its eradication.
smallpox
Fatal infectious viral disease of cattle, declared eradicated in 2011.
rinderpest
The ongoing eradication program has reduced cases of this viral disease to only 99 in 2024, all in Pakistan and Afghanistan.
polio
A painful and disabling parasitic disease caused by the nematode Dracunculus medinensis. Only 14 cases in 2024.
dracunculiasis (Guinea worm)
Rarely fatal but highly disfiguring disease caused by the spiral-shaped bacterium Treponema pallidum pertenue, a close relative of syphilis. Annual cases have been reduced from 50 million to less than 100,000.
yaws
An infection of the lymph system by mosquito-borne microfilarial worms, causing severe swelling of limbs. 21 of 83 endemic countries have ended transmission, but 40 million were infected worldwide in 2022.
lymphatic filariasis (elephantiasis)
Though complete eradication is unlikely due to wildlife reservoirs, the WHO aims to eliminate dog-mediated human deaths by 2030.
rabies
From 1900 to 2017, the number of endemic countries decreased from 200 to 86, but in 2022 there were still 249 million infections and 608,000 deaths. Experts say it could be eradicated by 2050.

Might want to add that this includes animal and human agents. Rinderpest affects cattle and not humans. Currently, smallpox is the only human disease that has been eradicated, with guinea worm approaching as the second.
