CommonHealth Live! | The Resurgence of Measles in the United States

Since January 2025, the United States has confirmed more than 3,000 cases of measles across multiple states - with South Carolina reporting nearly 1000 cases in just the first two months of 2026. The economic costs of these outbreaks pose a burden to local and state health agencies through hospitalizations, surveillance, and contact tracing, among other measures. Cases of pertussis are similarly high, with nearly 30,000 cases in 2025. Immunization coverage has stalled, and data indicate a rising trend of non-medical exemptions in states throughout the country. What is driving the resurgence of some vaccine-preventable diseases in the United States? Are we heading into a future of endemic measles, pertussis, and other disease outbreaks? How do the domestic outbreaks connect to global issues around immunization coverage and health security? 

Please join the CSIS Bipartisan Alliance for Global Health Security on March 12, from 10:00 to 11:00 AM ET, for a broadcast conversation with Katherine E. Bliss, Senior Fellow and Director, Immunizations and Health Systems Resilience, with the CSIS Global Health Policy Center and J. Stephen Morrison, Senior Vice President and Director, CSIS Global Health Policy Center, regarding the current outbreaks, the threats posed by sustained disease transmission, and opportunities for regional and international collaboration to prevent and respond to health security challenges.

This event is made possible through general support to CSIS.
