"This week, Reuters
reports that COVID-19 test kits used in Tanzania were dismissed as faulty by President John Magufuli. To check the reliability of the tests, according to Reuters, the president said he had instructed Tanzanian security forces wage a secret experiment. They had randomly obtained several non-human samples, including from a pawpaw, a goat and a sheep, but had assigned them human names and ages."
"Nevertheless, the samples from the pawpaw, goat, and sheep were all submitted for testing, knowing there is no way that they could have the virus. When the results came back, the samples for the pawpaw and the goat tested positive for COVID-19, the president said, adding this meant it was likely that some people were being tested positive when in fact they were not infected by the coronavirus, according to Reuters."
