Outbreak Watch: July 17, 2026

In this edition of Outbreak Watch, we provide a current briefing on the major outbreaks unfolding now, including Ebola in the Democratic Republic of the Congo and Uganda, New World screwworm in the United States, and the rapidly growing U.S. cyclosporiasis outbreak. Along the way, we answer the questions listeners are asking most. We also examine several emerging signals, including H5 avian influenza in mammals, the potential for Vibrio vulnificus infections this summer, and why surveillance systems are just as important as laboratories when it comes to detecting outbreaks before they become national emergencies. As always, you'll find annotated references, official dashboards, and links to additional resources in the companion blog post at InfectiousDose.com.
