Notice to Readers: Availability of Provisional AIDS and HIV/AIDS Data in Table IV and Pediatric HIV Surveillance Data in Table I

CDC is upgrading the national human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) surveillance data management system. During this transition, CDC will not update AIDS or HIV/AIDS surveillance data in the quarterly MMWR Table IV. In addition, CDC will not provide monthly updates of HIV infection data for persons aged <13 years in Table I. A footnote that explains this situation will be included with Tables I and IV during the period when no updates are available.
