Strangely, medical privacy is the reason anyone still dies from HIV. For the cost of 10 cents per person, we could test every human in the planet and make that information public. The transmission rate goes down (1/10th) if the infected person knows, and goes down further with the right immunosupressents (by a factor of 1/100). Publicly available data might even push that to 1/1000. The transmission rate is around 1, so that means it would be cut to 1 new infected per 1000 cases.
Within the standard life expectancy of a hiv carrier, we would go from 40 million to 40 thousand cases.
