Obesity, tobacco and vaccination policy were on the agenda at a national gathering of lawyers, professors and other public health professionals this week in Atlanta—but attendees keep coming back to Ebola.

In an informal poll taken during a Thursday morning session, about a quarter of the hundreds in the ballroom of the Loews Atlanta Hotel raised their hands when asked whether they have been called to answer an Ebola-related email or phone call since arriving for the conference. The first panelist of Thursday’s events, Northeastern University law professor Wendy Parmet, was supposed to kick things off by talking about the federal Affordable Care Act. “But how can we not talk about Ebola?” she asked.
