Is it true that Guinea worm cases fell from about 3.5 million in 1986 to 28 in 2018?

Yes. A CDC MMWR report states the number of Guinea worm cases fell from an estimated 3.5 million in 1986 to 28 in 2018, matching the claim exactly. Other sources confirm the 3.5 million 1986 baseline but cite different later-year figures (25,000 in 2006; 16,026 in 2004; 25 in 2016; 54 in 2019; 13 in 2022).
