Top medical experts studying the spread of Ebola
say the public should expect more cases to emerge in the United States
by year's end as infected people arrive here from West Africa, including
American doctors and nurses returning from the hot zone and people
fleeing from the deadly disease.
But how many cases?
No one knows for sure how many infections will emerge in the U.S. or anywhere else, but scientists have made educated guesses based on data models that weigh hundreds of variables, including daily new infections in West Africa, airline traffic worldwide and transmission possibilities.
This week, several top infectious disease experts ran simulations for The Associated Press that predicted as few as one or two additional infections by the end of 2014 to a worst-case scenario of 130.
"I don't think there's going to be a huge outbreak here, no," said Dr. David Relman, a professor of infectious disease, microbiology and immunology at Stanford University's medical school. "However, as best we can tell right now, it is quite possible that every major city will see at least a handful of cases."
Relman is a founding member of the U.S. Department of Health and Human Services advisory board for biosecurity and chairs the National Academy of Sciences forum on microbial threats.
Until now, projections published in top medical journals by the World Health Organization and the Centers for Disease Control have focused on worst-case scenarios for West Africa, concluding that cases in the U.S. will be episodic, but minimal. But they have declined to specify actual numbers.
