tl;dr: Omicron may have been introduced to Africa by Chinese "diplomats"

Which is consistent with it being created by china and deliberately spread (though certainly not proof).

If true, this is a fascinating form of bioweapon: a disease so mild you can use your own people to spread it. Only made effective by propaganda and fear, not actual harms.
