Updating CDC Links in MedlinePlus
MedlinePlus is in the process of updating its links to content from the Centers for Disease Control and Prevention (CDC) in response to a major CDC website revision. For more information, please see CDC Moving Forward.
This should have a very minimal impact on MedlinePlus Connect users. Direct links to the CDC are returned primarily in the reference list for lab test and procedure code requests to the MedlinePlus Connect Web Service.
If you encounter a broken link on the MedlinePlus website, please report it to NLM Customer Support.
