The Central African Republic is in the midst of one of the world’s worst, acute humanitarian crises—and no one is talking about it. Last April, epidemiologists concluded that mortality rates are four times what’s reported by the United Nations. People are dying in droves from preventable diseases that are exacerbated by violence, stemming from state-capture by the Wagner Group. One reason why this emergency garners so little attention is that thousands of deaths go unreported, similar to situations in Iraq, the Democratic Republic of Congo, and South Sudan. In a multimedia feature for Undark Magazine, Amy Maxmen covers these invisible crises.
