Health mandates-CDC and WHO jurisdiction in Wyoming.

HB 143 prohibits the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) from having jurisdiction in Wyoming. It explicitly states that requirements, mandates, or guidance from these organizations - such as mask, vaccine, or testing rules - cannot be enforced in the state or used to justify such mandates. The law takes effect July 1, 2023, and directly affects Wyoming residents and state/local authorities by blocking the use of federal or international health directives for public health enforcement. The bill creates a new statutory provision (W.S. 35-4-1001) to nullify CDC and WHO mandates within Wyoming's borders.
