Crimes of exposing another to contagious diseases and endangerment by bodily substance; revise elements and penalties.

HB 1003 revises Mississippi law to criminalize the *intentional transmission* of serious non-airborne infectious diseases (like HIV or hepatitis) instead of merely exposing others. It requires proof of specific intent to transmit and adds defenses, such as if the affected person knew the disease status beforehand or if transmission didn’t occur. The bill defines "substantial risk" using medical evidence and clarifies that failing to use protection (like condoms) alone doesn’t prove intent. It sets misdemeanor penalties (up to 1 year in jail or $1,000 fine) and includes specific provisions for transmission to corrections staff, visitors, or inmates. The bill died in committee in February 2026 and was never enacted.
