Chapter 17 of Contagion returns to Willow and heath advertising firm. Helen, the account representative for National Health hospital, which is the competitor of Manhattan General hospital, has learned that while National has a lower than average nosocomial infectious disease rate (nosocomial: hospital originated infection the patient would not have gotten if not hospitalized).
Helen takes this news to her boss, Robert Barker. Together they are developing Robert's idea that it would be a good thing if Terese's ad campaign for Manhattan General was rejected by the hospital. With the rejected ad campaign would go Terese's hopes of being promoted to president of the advertising firm.
Helen then shares the nosocomial rate news (or at least the outline of it) to Terese who realizes it might good to consult Jack and Chet about the ad. Colleen volunteers to make the phone call since she and Chet had had such a lovely evening out the night before.
"Having Jack and Chet take a look at this is not a bad idea," Terese said. "A professional response might be helpful."
"I'd be happy to make the call,' Colleen offered.
