Return to Public Health- Undeliverable letters of Communicable Disease Patients

Reaching contagious people in a timely manner is essential to limit disease spread. We examined communicable disease cases with undelivered mail to ascertain failure causes and rates. We identified the source of address, reason for return and patient demographics from the case files. This yielded a framework of address information flow. This framework allows us to establish a baseline for future research including cost-effectiveness analyses for streaming lining the process for improvements.
