Containing the ‘epidemic’

Akpan said the number of cases has fallen since April after local authorities halted illegal mining and began evacuating residents.
“We are doing a lot to contain the epidemic,” he said.
“We have been able to get on top of this. The number of reported illnesses have fallen. We are winning.”
The impoverished state of Zamfara is rich in minerals including gold, copper, iron ore and manganese.
Goodluck Jonathan, Nigeria’s president, recently inaugurated a mineral processing plant in the state, which is seeking to attract investment.
