While the world grapples with the deadly novel coronavirus COVID-19, a different but familiar disease appears to be quietly spreading across Nigeria. Lassa fever was first diagnosed in 1969.

This has prompted the Nigerian Academy of Science to call for a national public health emergency to be declared. Doyin Odubanjo explains the academy’s
