If you notice these deaths are in the area of amaMpondo i.e Lusikisi, Mount Fere ect. In the history of this tribe there was no circumcision but because of some boys going to educate themselves in the Xhosa area i.e Mthatha, Mqanduli, Dutywa, Alice ect when they arrive there they got pressued as they were categorised as boys. All of this resulted in amaMpondo adapting the culture, meaning their ancestors do not even know of such a culture and now they are dying of ukuphapha and doing things wrong.
To add on, these dying patients seek medical attetion in Mthatha (Xhosa are) were the culture originates, meaning banonzululwazi amaXhosa when it comes to this and that is why it is rare for our boys to face such difficulties in the culture.
