What happened

It started with an email that arrived late on Friday, 1 May 2026, a public holiday, from a concerned colleague.

Why it matters

The message was from a UK infectious disease specialist to Professor Lucille Blumberg of the South African National Institute for Communicable Diseases (NICD), and it set events in motion that led to her team finding a rare virus as the cause of an outbreak…

Common ground

Blumberg recounted the team’s efforts before Parliament’s Portfolio Committee on Health this week.

Perspective signals
