One example is the notion that Africa’s AIDS epidemic is the result of HIV contaminated medical practices. The idea that HIV spread in Africa via contaminated medical instruments is derived from a theory of how AIDS originated in Africa in the first place. This theory states that African bush hunters became infected with a non-human primate virus, Simian Immune Deficiency Virus (SIV) which then mutated and was spread through reused vaccination syringes and other medical equipment.
