This is from the IMF’s Monique Newiak:

In summary:

Non-commodity exporters, around half of the countries in the region, continue to perform well with growth levels at 4 percent or more. Those countries benefit from lower oil import prices, improvements in their business environments, and strong infrastructure investment. Countries such as Côte d’Ivoire, Ethiopia, Senegal, and Tanzania are expected to continue to grow at more than 6 percent for the next couple of years.

Most commodity exporters, however, are under severe economic strain. This is particularly the case for oil exporters like Angola, Nigeria, and five of the six countries from the Central African Economic and Monetary Union, whose near-term prospects have worsened significantly in recent months despite the modest uptick in oil prices. In these countries, repercussions from the initial shock are now spreading beyond the oil-related sectors to the entire economy, and the slowdown risks becoming deeply entrenched.

It should be obvious, but it bears repeating that there is quite a bit of variation in economic performance across the 55 states on this vast continent.

My personal Africa growth index consists of Senegal, Cote d’Ivoire, Nigeria, Ghana, Gabon, Cameroon, Ethiopia, Kenya, Zambia, Angola, and South Africa. And despite ongoing turbulence in a number of the key economies in this basket, I am confident that the turbulence will not completely erase the gains of the last two decades.
