Your post is misleading. It will still be a crime, just not a felony.

Some excerpts:
"California lawmakers are re-evaluating a 30-year-old law on HIV disclosure. Right now, intentionally exposing someone to HIV is a felony that could result in seven years in prison. But some state leaders call it discrimination and want the laws to reflect advances in modern medicine.
Senate Bill 239 aims to change laws that criminalize and stigmatize people living with HIV. Furthermore, the authors hope to make laws consistent with laws regarding other infectious diseases."
[...]
"When these laws were enacted, there was no effective treatment for HIV,” said state Sen. Scott Wiener (D-San Francisco) who wrote SB 239. “It was for many people a death sentence.”
But Wiener said it’s a new era, with new medication that makes the likelihood of infecting another person with HIV very low.
“You don’t reduce HIV infections by classifying people as felons,” Wiener said. “You reduce HIV infections by giving people access to healthcare and information.”
Weiner explained that knowingly exposing someone to other infectious diseases is classified as a misdemeanor and said he thinks HIV should be no different. But not everyone has the same perspective."
