Well-written, accurate, and accessible reports are critical tools for communicating public health data and for advancing policies that are responsive to the issues data reveal. All public health agencies should produce data reports and tailor them to a variety of audiences. This short course provides guidance on writing data reports, suggestions on how and when to produce specific kinds of reports, and ideas to help organizations assess their report-writing needs. The course is designed for surveillance and epidemiology staff who wish to communicate data to external audiences, and also to communications staff who wish to incorporate data into ministry or health department communications products or websites.
