You can read about it here. There are four more cases to come that we don't even know the names of, but it's possible they are the remaining athletes (like Kumari Taki) who were withdrawn last minute from the Commonwealth Games without much clarity, or other athletes whose lack of competition might seem odd/unexplaines. What's most unusual about this is this spate of positive is for a class of drug (glucocorticoid) that isn't banned out of competition (these are all in-competition busts). It also is not something that Kenyans or other athletes tested positive for much until 2021-22. And now it looks like it will take out 10 athletes in under 2 years, all Kenyans. Would like to know more from someone who knows more about the substance, but these seem like pretty needlessly dumb busts. Even if these substances do help, unless an athlete has a TUE they will be busted for them each and every time. Hopefully whatever athlete, agent, or third party that is providing these to athletes is either caught or becomes a black sheep because there can't be any dumber form of doping than this.
