“The polio virus, as it is frustratingly inclined to do, has rebounded again despite the ongoing, determined effort aimed at worldwide eradication,” development blogger Tom Paulson writes in the Humanosphere blog, noting the virus has caused active infections in Ethiopia and Somalia and been found in sewage in Israel. “The main driver, arguably, for the recent surge polio cases is conflict, instability and, of course, ongoing poverty,” he states, reviewing several recent media reports on polio. “The world may yet defeat polio, but it’s important to recognize that the root cause here is chaos and poverty,” he writes, adding, “Unless we are also working to eradicate those two drivers of diseases of poverty, we’ll just have to keep doing whack-a-mole with a new and different mole” (8/23).
