The Centers for Disease Control and Prevention (CDC) has announced a temporary pause on testing for 31 infectious diseases, including rabies, chickenpox, and the Epstein-Barr virus. This decision comes as part of a quality review initiated in late 2024, which aims to enhance the CDC's laboratory operations through the establishment of the Office of Laboratory Systems and Response. A CDC spokesperson emphasized that the agency is committed to maintaining high standards in laboratory testing and is in communication with state and local health departments to facilitate alternative testing solutions if necessary. The CDC is currently facing significant challenges, including staffing shortages that have limited its capacity to provide after-hours assistance to states. The agency anticipates that some tests may resume in the coming weeks, ensuring continued support for public health needs.
