Outbreak Watch returns with updates on three unfolding biological events and the systems responding to them.

This week:

• The Bundibugyo Ebola outbreak in the Democratic Republic of the Congo becomes the largest on record as contact tracing, clean water access, and response operations face growing challenges.

• The Andes hantavirus outbreak linked to the MV Hondius cruise ship is behaving as expected, providing an important lesson in what successful containment looks like.

• New World screwworm detections in the United States highlight ongoing debates about surveillance, preparedness, and the challenges of responding to an emerging threat when critical systems must be rebuilt.

In this episode, we explore visibility, uncertainty, and the operational realities that shape outbreak response long before most people hear about it.
