As global health systems face increasingly complex disease threats, the focus is shifting toward preparedness, particularly when it comes to early detection, diagnostics, and surveillance. Emerging infectious diseases, including hantaviruses such as the Andes virus, are a reminder of how quickly health risks can evolve in an interconnected world.

 While these diseases may not yet pose a widespread threat locally, they highlight critical gaps in laboratory capacity, frontline detection, and access to timely testing. Healthcare experts say strengthening diagnostic systems and supporting frontline healthcare workers will be key to responding effectively to future outbreaks.

Mpho Sithole spoke to Jonathan Keytel, Director of Strategy and Innovation at Roche Diagnostics, Africa to unpack how global health threats are reshaping the conversation around diagnostics and preparedness.
