Polio, like Covid-19, is spread via fecal matter and therefore can contaminate water and other surfaces. The oral polio vaccine was credited with helping to eradicate the wild polio virus from the African continent. Now the polio vaccine has escaped as a live virus and is in the wild in Africa paralyzing children.
It is unclear what use purpose the World Health Organization is providing, if any.
UN says new polio outbreak in Sudan caused by oral vaccine
In a statement this week, WHO said two children in Sudan — one from South Darfur state and the other from Gedarif state, close to the border with Ethiopia and Eritrea — were paralyzed in March and April. Both had been recently vaccinated against polio. WHO said initial outbreak investigations show the cases are linked to an ongoing vaccine-derived outbreak in Chad that was first detected last year and is now spreading in Chad and Cameroon.
