Polio first.
"in 1996 .... wild poliovirus paralyzed an estimated 75,000 children on the continent each year. Now the continent has not reported a case of wild polio since August 2016, and the Independent Africa Regional Certification Commission says the World Health Organization's Africa region is free of wild polio."
The vaccination campaign "has prevented an estimated 1.8 million cases of paralysis in children and saved about 180,000 lives"
The article you cite doesn't provide a total but it indicates very few infections from the new virus. Are you concerned there won't be an improved vaccine for the new one?
