It's Contagious

What happens when a hundred people sneeze without covering their faces? How does hand-washing save lives? This eight-week unit explores infectious disease, and is led by leading epidemiologist ____ from ____. He/she guides through a sequence of one-on-one chats the study of several contemporary infectious diseases--Ebola, Avian flu, Tuberculosis—as well as the behavioral, social and cultural factors that drive the spread of infection. A variety of summary and deep-dive readings explore the behavioral dimensions of infectious disease, and illustrate how contagion follows an algorithmic growth pattern, calling on understanding of exponents. Questions are also raised about appropriate public policy responses, highlighting the sometimes conflicting objectives of public health and personal freedom and mobility.
