Social Contagion presents the untold story of the COVID-19 outbreak in Wuhan. Chuang, a collective of communists living inside and outside China, chronicle the struggles of everyday people caught between a lethal virus and a repressive state. They argue that China's rapid but fragile economic growth has created the social and biological conditions for new and deadly viruses, of which COVID-19 was merely the latest iteration. Through on-the-ground interviews, reports, and analysis, Social Contagion gives us a piercing portrait of the simultaneously draconian and ineffectual response of the Chinese state, as well as the self-organizing survival strategies of ordinary Chinese workers. Chuang concludes that the pandemic has enabled a new mode of counterinsurgent governance, one rooted in decades of institutional experimentation and an emergent theory of statecraft.
