An accessible and diverse resource for infectious disease outbreak response. For too long, the theory and practice of infectious disease outbreak response have been the domain of a small number of experienced responders. The COVID-19 pandemic brought global attention to the requirements of effective outbreak response, and the need for preparation across the key pillars. Decisionmakers, early career practitioners, and those in the field now have access to a comprehensive text that brings together evidence-based and practical insights from the best in the business. Dale Fisher, Professor of Medicine at the National University of Singapore, was chair of WHO's Global Outbreak Alert and Response Network before and during most of the pandemic. In this massive collaborative effort, he marshals nearly one hundred top public health leaders and experts from the front lines to present thirty-seven chapters on pandemic preparedness and response, drawing heavily on experiences from COVID-19, but also from Ebola, MERS, SARS-1, influenza, and other outbreaks of modern times. The contributors include experts from health ministries and Centres for Disease Control and national public health institutions around the world; from international organizations like the WHO, MSF, IFRC, and UNICEF; and research institutions and various NGOs from dozens of countries, adding to the diversity and richness of the descriptions.
