Sickle Cell Disease Monitoring

CDC is working to improve the lives of people with sickle cell disease (SCD), an inherited blood disorder. Learn about CDC’s SCD monitoring projects, and find a suite of online resources that can help you or someone you know live healthy with SCD.

Sickle cell disease (SCD) is a blood disorder present at birth. People with SCD have “sickle” shaped red blood cells that stick together and block blood and oxygen from reaching all parts of the body, leading to health problems such as pain, anemia, infections, and stroke. Approximately 100,000 Americans are affected by SCD. CDC is committed to studying SCD to improve the health and care of people with this condition.

CDC Monitoring Projects

CDC, and participating states, began SCD surveillance (monitoring) in 2010 to learn more about people with SCD and the health problems they experience. SCD monitoring involves collecting information on diagnoses, treatments, and healthcare access for people with SCD in the United States.


Learn more about CDC’s SCD surveillance history through a fact sheet that allows you to compare each project using information about data sources, participating states, and accomplishments of each project.

CDC coordinated these efforts as part of three projects:

The SCDC program, which has been ongoing since 2015, is CDC’s current monitoring project. The SCDC program collects health information about people with SCD to study the long-term trends in diagnosis, treatment, and healthcare access for people with SCD in the United States. Currently, Georgia and California are the states participating in the SCDC program. As more resources become available, CDC plans to expand the program to include additional states. The program will help inform policy and healthcare standards to improve and extend the lives of people with SCD.

Learn more about the Transfusion Complications Monitoring project.

The Transfusion Complications Monitoring project is a collaboration between CDC, Georgia State University, University of Florida, and the UCSF Benioff Children’s Hospital Oakland. Some people with SCD and thalassemia may require blood transfusions to stay healthy, but, sometimes, they may experience health problems after receiving blood transfusions. This project aims to learn more about transfusion-related health problems and to identify ways to decrease these health problems to improve the health of people with SCD, thalassemia, and other red blood cell disorders.

Other Online Resources

For Patients and Caregivers

  • SCD materials webpage has fact sheets and infographics on living well with SCD. SCD resources are also available in Spanish at our SCD Spanish webpage.
  • Sickle Cell Disease National Resource Directory is a listing of national agencies, specialty healthcare centers, and community-based organizations that provide services and resources for people affected by SCD. The goal of this directory is to help people find SCD services and resources. Users can search for Providers/Sickle Cell Centers, Non-Profits/Associations/Foundations, and Support Groups within their state.
  • Sickle Cell Trait Toolkit is a collection of fact sheets covering various health problems affecting people with sickle cell trait.
  • Stepping Up: A 2-part video series for teenagers and young adults with SCD. The videos share the stories of Kevin and Calvanay, two young adults with SCD, and their transition to adult care, how it has affected them, and how they’ve overcome challenges. Spanish transcripts of the videos are available online.
  • SCDC webinars, hosted by the SCDC program in California, are free and open to the public. Watch previous recordings or sign up to join the email list for announcements about upcoming webinars.
