Early Detection of Public Health Emergencies of International Concern through Undiagnosed Disease Reports in ProMED-Mail

摘要

We conducted a retrospective analysis of all reports in ProMED-mail that were initially classified as undiagnosed diseases during 2007-2018. We identified 371 cases reported in ProMED-mail; 34% were later diagnosed. ProMED-mail could be used to supplement other undiagnosed disease surveillance systems worldwide.
