That there is no coronavirus COVID-19 reported in Subsaharan Africa is a huge concern.
1) It seems likely that this virus spread out of China in part by Chinese people working or visiting overseas.
2) China has had a long standing diplomatic and commercial presence in several areas of Subsaharan Africa including the Congo and Sudan, and some other places.
3) These are places where illness are only barely monitored and generally not well reported.
My guess is that coronavirus COVID-19 is in the Congo and Sudan and a few other places, and it is not being addressed.
