^aNote that at the time of this writing, some countries were at their maximum exponential infection dissemination (different epidemic phases). For these countries, no final exponential score had been reached yet. However, this does not count for future predictions.

^b↑, ↓, and = denote increase, decrease, and no change, respectively.
