After the 2026 Measles Summit, participants identified where clearer guidance, practical resources, and coordinated effort could make the most difference. The Collaborative's work falls into five areas:

• Outbreak response and public health: Helping public health agencies and community partners assess needs, respond to outbreaks, and reach affected populations.
• Exposure and infection prevention and control: Clarifying how exposures are assessed and how healthcare settings prevent and control transmission, including exposure windows and care of exposed infants.
• Clinical care: Supporting clinicians in recognizing, diagnosing, and managing measles, particularly in infants, pregnant patients, immunocompromised patients, and people with serious complications.
• Communication and education: Helping clinicians and trusted messengers talk about measles and vaccination, and making information easier to share with communities.
• Evidence and research: A peer-reviewed journal supplement drawing on clinical and public health expertise, and identifying questions that need further study.

Individual projects move forward based on need, available expertise, and the capacity of partner organizations.

National Measles Registry

Ongoing US outbreaks highlight that the current epidemiology of measles is changing and new vulnerable populations have emerged. The Measles Collaborative seeks your assistance in soliciting cases of patients with a confirmed or probable diagnosis of measles and/or post-measles complication. This is a multi-site collaboration to improve our understanding of contemporary measles and short- and long-term complications.  If you are willing to contribute to this national effort, please reach out to measles@health.ucsd.edu(opens in new tab) before or after your first case so that we can send you study materials and a secure link for sharing information.
