Q&A: Is AI democratizing global health or reinforcing old inequities?

Artificial intelligence is rapidly transforming the tools that are central to global health decision-making in areas like disease control policies, financing and vaccination strategies, such as infectious disease modeling. This brings new opportunities to the modeling landscape, but could also exacerbate existing disparities, according to Matt Ferrari, professor of biology and director of the Center for Infectious Disease Dynamics at the Huck Institutes of Life Sciences at Penn State.
