  Global public health surveillance relies on reporting structures and
transmission of trustworthy health reports. But in practice, these processes
may not always be fast enough, or are hindered by procedural, technical, or
political barriers. GPHIN, the Global Public Health Intelligence Network, was
designed in the late 1990s to scour mainstream news for health events, as that
travels faster and more freely. This paper outlines the next generation of
GPHIN, which went live in 2017, and reports on design decisions underpinning
its new functions and innovations.
