The models suggest that the best way to mitigate the epidemic isn’t through travel restrictions, but through early detection, public health interventions and behavioral changes.
The open-access findings were published today by the journal Science, by a research team including scientists from the U.S., Italy and China.
Elizabeth Halloran, a biostatistician who works at Seattle’s Fred Hutchinson Cancer Research Center and the University of Washington, is a member of the team. She told GeekWire that the right public health strategies will give researchers more of an opportunity to develop diagnostics for COVID-19 infections as well as the signs of past infection.
