In the late 1990s, South Africa’s President Thabo Mbeki decided that mainstream science had AIDS wrong. A small circle of “truth-tellers” convinced him that AIDS came from poverty and malnutrition, not a virus. He warned that anti-retroviral therapy (ART) was toxic and that pharmaceutical companies were poisoning Africans for profit.
His government stalled the rollout of ART. Health Minister Manto Tshabalala-Msimang pushed garlic, beetroot, and lemon as medicine. “Nutrition is the basis for good health,” she said, insisting that exercise and diet, not Western drugs, were the real treatment. She warned that antiretrovirals had side effects, including cancer, that the establishment was hiding. When scientists showed data, she waved it off: “No churning of figures after figures will deter me from telling the truth to the people of the country.”
The result was a public health disaster: hundreds of thousand of preventable deaths (see also here and here).
A reminder of what happens when authority trades evidence for ideology.
