Why Are South African Countries Seeing an Uptick in Pellagra?

During the coronavirus pandemic, a global economic collapse, and increasingly frequent and severe droughts, what better time for southern African countries to see upticks in another disease: pellagra. Pellagra, a disease caused by chronic deficiencies in Vitamin B3 (niacin), is prevented with nothing more than a half-decent diet. So why is it still here in 2020? Today, we go on a journey through history to figure out what caused this vitamin deficiency disease to appear, why it still exists, and what we can do about it.
