Appropriations: supplemental; funding to test for avian influenza (H5N1) in hospital settings; provide for. Creates appropriation act.

HB 4171 provides supplemental state funding for hospitals in Michigan to test for H5N1 avian influenza (bird flu) in clinical settings. It directly affects hospitals and healthcare facilities that need to conduct these specific tests. The bill creates a new appropriation (funding line) to cover the costs of testing, ensuring hospitals have resources to screen patients for H5N1. This is a funding measure, not a policy change, and it applies to the 2025 fiscal year.
