Which populations are most at risk for cVDPV outbreaks?

Explanation:
cVDPV outbreaks happen when the oral polio vaccine virus can keep circulating in a population with low immunity. The live attenuated virus in OPV can mutate as it passes from person to person, sometimes regaining the ability to cause paralysis. In communities with high vaccination coverage, herd immunity blocks transmission, so outbreaks are unlikely. Being highly immunized protects against spread, and non-human animals aren’t a reservoir for polio, while adults in healthcare settings aren’t specifically the group at highest risk. Therefore, under-immunized populations are the ones most at risk for cVDPV outbreaks.
