JUDY WOODRUFF:

The appointment of an Ebola czar was greeted with a mix of support and real skepticism over the president's choice for the job.

We look at his possible role, as questions keep escalating about just how prepared the U.S. health system is.

Two voices from the world of public health tonight. Pamela Cipriano is president of the American Nurses Association. It's a professional organization representing the nation's 3.1 million registered nurses. And Dr. Amesh Adalja is an infectious disease physician and a representative of the Infectious Diseases Society of America, whose members include doctors, scientists and other health care professions.

We welcome you both to the "NewsHour."

To you first, Dr. Adalja.

Looking at Ron Klain, who the president appointed to coordinate government efforts on Ebola, what does he need to do, do you believe?

DR. AMESH ADALJA, Infectious Diseases Society of America: He really needs to coordinate a response.

You have got multiple agencies that have responsibilities now, the CDC, the FDA, Department of Defense, USAID. We need an integrated response where everybody is talking to everybody and there's one plan that's going to be executed to stop this outbreak in West Africa and also keep Americans safe here in the United States.
