Nigeria: Cholera Still On Rampage
BY JUDD-LEONARD OKAFOR, 28 FEBRUARY 2012
Comment
Kaduna ? The annual rampage of the cholera disease is now so predictable that millions of Nigerians rarely pay attention to it.

Yet, its re-occurrence in areas most prone, have had devastating effects with death numbers steadily climbing. In the midst of these harvest of deaths, we also have oasis of hope, that is the near cholera free states. Why are some states cholera prone and some cholera free? Daily Trust Health Insight investigates.

The casualties started trickling in before the rains began last year. Five deaths in Adamawa, 30 in hospital; 11 deaths in Nasarawa; another 11 deaths in Oyo. They spanned 203 local government areas across 26 states.

With a fatality ratio estimated at 3.2%, the disease claimed 742 lives by year end. Epidemiologists in weekly updates overseen by the federal health ministry recorded a total 23, 377 cases.
