It's worth watching the video before it is deleted.
Tanzania’s President Mocks Covid Tests - ingenuousness
The video is 8 minutes long. He reads through some negative, some indeterminate, some positive Covid test results. He's not the only one reporting such random results - school children performed the PCR and found orange juice tested positive. The test is known to be fake. The WHO version of the PCR uses a strand of molecules present in human DNA as a reference - that should get some positive results, eh?
Nothing there at the link except words saying it was the wrong “African President, and yes one guy died, but it was another African President...blah blah blah
