Rankings
The following were the rankings at the beginning of the season.

Uganda women in Kenya
Originally planned as a three match series with the first game in Kenya and the other two in Uganda, the two matches in Uganda on 20 and 23 December were cancelled earlier in December, as was a men's match on 16 December between the two countries which would have been a double header with the women's game.
