A 52-year-old man has become the first in Canada to be convicted of murder under a new law that aims to prevent the reckless spread of AIDS, the Australian Associated Press reports.

Johnson Aziga was found guilty this weekend of murdering two women and sexually assaulting others by not warning them that he was infected with the virus that causes AIDS before having unprotected sex with them.

Aziga was diagnosed with HIV in 1996 and was under a public health order to inform potential lovers.

"It's certainly precedent-setting here in Canada because we now have a conviction for first-degree murder involving HIV transmission," prosecutor Karen Shea told the Ottawa Citizen.

Seven of Aziga's partners became infected and two died of AIDS-related cancers. Sentencing is scheduled for May 7.
