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.
HIV treatment has gotten a lot better since then, and the new law is meant to reflect that. HIV drugs help prevent transmission, and HIV patients' life expectancies are now "near-normal."
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.
In 1995, the height of the AIDS epidemic in the U.S., more than 50,000 people died of the disease. In 2014, the last year with statistics, there were only about 6,700 deaths attributed to HIV.
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.
