This isn’t only in Uganda...I first ran across it in Liberia. But in countries with good governments, it is prosecuted. Uganda is getting out of a lot of chaos and civil wars (remember Idi Amin? the “lord’s liberation army”? to name just two).
My missionary friends say that since HIV hit, a lot of nominal “Christians” are going to witch doctors for cures which involve witchcraft...
But before you point fingers, remember that good Africans are aghast that the US allows the abortion of a child for convenience. They consider abortion as a form of witchcraft too...and not only is it legal in the US, the US taxpayers are pushing abortion and “sex education” on Africa (and here in the Philippines for that matter).
So killing a kid and putting his/her genitals under your store so you can be successful is terrible, but so is pressuring your daughter or girlfriend to abort her unborn child so you aren’t stuck with the bill supporting it.
