Modifies provisions relating to infectious or communicable diseases

HB 2456 repeals 22 existing Missouri statutes and replaces them with 14 new sections focused on infectious disease policies. The bill specifically requires the Missouri Department of Health and Senior Services to cover HIV testing costs for victims of rape, sodomy, or incest - only if the perpetrator was HIV-positive and tested during incarceration. This funding is limited to two HIV tests per year for up to five years after the crime occurred, following current medical guidelines. The bill also updates definitions for terms like "HIV testing" and "serious infectious disease" to align with modern medical practices. It directly affects crime victims seeking post-assault care and the state health department managing related costs.
