CDC Responds to Measles Outbreaks in SC & NC: Vaccination & Support Efforts
The Centers for Disease Control and Prevention (CDC) is bolstering its response to rising measles cases across the United States, particularly in South Carolina and North Carolina. This renewed commitment involves deploying disease detectives and providing extensive resources to state and local health departments, aiming to contain outbreaks and prevent further spread of the highly contagious virus. The CDC’s actions come as the nation grapples with a significant increase in measles cases, with 1,281 confirmed cases reported in 2026 as of March 5th, a substantial rise from the 2,283 cases reported for all of 2025.
On-the-Ground Support and Data Analysis
At the request of South Carolina officials, CDC’s Epidemic Intelligence Service (EIS) officers are actively supporting response efforts in the state. These specialists will work alongside state and local public health officials to analyze outbreak data from both South Carolina and North Carolina. This collaborative approach is designed to pinpoint transmission patterns, refine containment strategies and focus vaccination efforts where they are most needed. Dr. Linda Bell, a South Carolina epidemiologist, noted that the CDC team will specifically evaluate measles transmission within school settings, a crucial step in strengthening future containment measures. Spectrum News reported that the team will spend the next two weeks collecting and analyzing data.
A Comprehensive Suite of Resources
The CDC isn’t simply providing personnel; it’s offering a broad range of “surge resources” tailored to the specific needs of each region. These include assigning experienced technical and epidemiologic experts – including a CDC epidemiologist already embedded within the South Carolina Department of Public Health – and providing advanced laboratory testing, including genomic sequencing, to quickly identify and track cases. The agency is also leveraging robust data analysis, outbreak modeling, and even wastewater testing to gain a real-time understanding of the situation. Direct support for case classification, mitigation strategy development, and access to vaccines are also key components of the response. The CDC is offering guidance on infection prevention, control, and post-exposure prophylaxis, alongside educational materials for community outreach and strategic risk communication.
Understanding Measles and its Resurgence
Measles is a highly contagious viral infection that can lead to serious complications, including pneumonia, encephalitis (brain swelling), and even death. It spreads through the air when an infected person coughs or sneezes. The virus is so contagious that if one person has measles, 90% of those who are not immune will become infected. The current increase in cases is largely attributed to declining vaccination rates. The measles, mumps, and rubella (MMR) vaccine is highly effective, providing approximately 97% protection after two doses. However, vaccination rates have fallen in some communities, leaving pockets of susceptibility.
The Importance of Trust and Collaboration
Acting CDC Director Jay Bhattacharya emphasized the critical role of trust and collaboration in effectively addressing the measles outbreaks. “Trust is the foundation of public health, earned through openness, honesty, and guided by the best available evidence,” he stated during a national webinar with over 2,000 public health partners. Bhattacharya assured partners that the CDC is actively listening to state and local leaders and is prepared to provide a wide range of tools, including vaccine supplies, to support their efforts. This emphasis on partnership reflects a recognition that a successful response requires coordinated action at all levels of government and within communities.
Prevention: The Cornerstone of the Response
The CDC continues to underscore that vaccination remains the most effective way to prevent measles and protect communities. The benefits of the MMR vaccine significantly outweigh the risks, with serious reactions being extremely rare. Vaccination not only protects the individual but also contributes to “herd immunity,” safeguarding those who cannot be vaccinated, such as infants too young to receive the vaccine or individuals with certain medical conditions. The CDC recently shared a video message outlining its comprehensive response, highlighting the agency’s surge of resources and continued emphasis on MMR vaccination.
Current Case Numbers and Outbreak Locations
As of March 5, 2026, the CDC reports 1,281 confirmed measles cases in the United States, spanning 31 jurisdictions including Alaska, Arizona, California, Colorado, Florida, Georgia, and New York. A significant portion of these cases – 89% – are linked to ongoing outbreaks, with 237 originating in 2026 and 900 stemming from outbreaks that began in 2025. Four cases have been reported among international visitors to the United States. You can find detailed, updated case information on the CDC’s Measles Cases and Outbreaks page.
Looking Ahead: Ongoing Surveillance and Support
The CDC remains fully engaged in protecting the nation’s health and will continue to provide transparent updates and coordinated support to communities. Ongoing surveillance is crucial for identifying new cases and outbreaks, and the agency is committed to working with state and local partners to ensure they have the resources they need. The CDC Foundation is also playing a role, providing additional support to response activities. The agency will continue to monitor the situation closely, adapt its strategies as needed, and emphasize the importance of vaccination as the primary means of preventing measles and protecting public health. The CDC will also continue to analyze data and refine outbreak models to better understand transmission dynamics and inform targeted interventions.
