Cases of coronavirus, or COVID-19, have now spread to at least 75 countries, infecting nearly 100,000 people across the globe—most in China, the epicenter of the outbreak.

With concerns about the disease rising, we asked a group of RAND researchers to answer a wide range of questions about the crisis:

• Jennifer Bouey, the Tang Chair in China Policy Studies at RAND, is an epidemiologist whose research focuses on global health strategies and the social determinants of health.
• Courtney Gidengil is a senior physician policy researcher who is board-certified in both general pediatrics and pediatric infectious diseases.
• Mahshid Abir is a senior physician policy researcher whose research focuses on hospital surge capacity and the effects of overcrowding at medical facilities.
• Andrew Mulcahy is a senior policy researcher who studies prescription drug and health care payment policy.
• Lori Uscher-Pines is a senior policy researcher whose work focuses on health care delivery via telemedicine, as well as emergency preparedness and response.
• Elizabeth Petrun Sayers is a behavioral and social scientist who researches how traditional and new media shape risk perceptions and health behaviors.
