A lot of the media coverage about Nigeria this year focused on two things: Ebola and terrorism. But the West African nation actually had a pretty good year from a global health perspective. While it’s one of three countries still plagued by polio (alongside Pakistan and Afghanistan), I don’t think it will be on that list for long. Nigeria reported just six cases of polio in 2014, compared with more than 50 last year. What’s more, the infrastructure built to fight polio made it easier for Nigerian health workers to swiftly contain Ebola. The fact that Nigeria is now Ebola-free is a great example of how working to fight diseases like polio better equips countries to tackle other outbreaks.
