Relating to newborn or infant testing for congenital cytomegalovirus.

HB 4882 requires Texas birthing facilities to test every newborn or infant for congenital cytomegalovirus (CMV) - a virus that can cause hearing loss or developmental delays - before hospital discharge, alongside existing hearing screenings. This applies to all infants born at the facility unless parents decline the test, the infant is transferred to another facility, the test was already done, or the infant was discharged within 10 hours with a referral made. The law updates Texas Health and Safety Code Section 47.003 to include CMV testing under the newborn screening program, with data tracked by the state health department. It takes effect September 1, 2025, and directly affects newborns, parents, and birthing facilities across Texas.
