California Gov. Jerry Brown signed a law Friday reducing the penalty for knowingly exposing someone to HIV from a felony to a misdemeanor.
The old set of laws was rooted in the early 1980s. At the time, there weren't effective treatments for HIV, and there were rumors of people intentionally infecting sexual partners with the disease.
People at high risk of getting HIV can take a medicine known as pre-exposure prophylaxis, which greatly reduces the risk of getting the virus.
There has been some pushback to the law. Republican state Sen. Joel Anderson said he doesn't think people who would intentionally infect others should get lighter sentences.
