Public Health Alerts
Published by NEJM Evidence in collaboration with CIDRAP, Public Health Alerts are brief reports that inform public health officials, clinicians, policymakers, and the public of important and emerging health issues. Freely available on both the NEJM Evidence site and here, these reports are published on a rapid review track in support of efforts to make timely decisions for the medical community and public health.
For more information, read the news release and NEJM Evidence editorial on the launch.
