DHAKA – Since COVID-19 engulfed the world two years ago, “unprecedented” has become something of a buzzword. But while the coronavirus has posed unique challenges at a time of deep global interconnectedness, pandemics are nothing new. The COVID-19 pandemic is not even the only one we are currently experiencing. In much of the developing world, cholera outbreaks are proliferating.
