Infectious disease experts predict anywhere from a mere one or two additional cases of Ebola to a worst-case scenario of 130, according to simulations conducted for the Associated Press.

Almost all of the predicted cases will be healthcare workers returning from West Africa.

“I don’t think there’s going to be a huge outbreak here, no,” Dr. David Relman, a professor of infectious disease, microbiology and immunology at Stanford University’s medical school, told the AP. “However, as best we can tell right now, it is quite possible that every major city will see at least a handful of cases.”

A total of eight patients have currently been treated for Ebola in the U.S.
