“Plus I believe that Nigeria is stonewalling on their reporting. “
There’s probably good reason for this. Nigeria needs food, medicine and other supplies and if ships stopped delivering it they’d have a different problem.
Having said this it would be a good idea to limit all travel to Africa to essential, official contacts only. Ships offloading should be isolated from indigenous contacts. But, that won’t happen until it’s too late.
That has potential to cause much more severe impact later.
