Invitation to Public Keynote “The 1918-1919 Influenza Pandemic: Health and Economic Impacts”

by Prof. Dr. Karen Clay | Carnegie Mellon’s Heinz College

The COVID-19 pandemic took the world by surprise. While the first documented case was in December of 2019, it would take just three months before the World Health Organization (WHO) would declare that COVID-19 was a pandemic. As of March 2022, COVID-19 has been officially responsible for more than 6 million deaths.
As the COVID-19 pandemic has unfolded, many are drawn to the parallels with the 1918 influenza pandemic. Both are respiratory diseases caused by a virus, could spread from casual close contact, and reached most parts of the globe within months. The case mortality rates for both pandemics are higher than a typical seasonal influenza, with the 1918 influenza pandemic killing tens of millions worldwide. In both pandemics, non-pharmaceutical interventions (NPIs) like social distancing and mask wearing were used to control the spread, though in 1918 the restrictions were far less stringent. These parallels have renewed interest in understanding the health and economic effects of the 1918 pandemic.

This talk will survey the literature on the 1918 influenza pandemic, with a particular focus on understanding its health and economic effects. It will begin by providing an overview of key contextual and epidemiological details. Karen Clay will then examine spatial variation in the effects of the pandemic, including spatial variation in mortality and in the associated economic effects. The factors underlying this variation, including the role of non-pharmaceutical interventions will be discussed. Throughout the talk she will highlight important areas for future work.

Influenza viruses are responsible for substantial human morbidity and mortality and continue to present a public health challenge. In addition to humans, influenza viruses can infect birds, pigs, horses, dogs, sea mammals, and other animal species. It has been proposed that pigs are intermediate host “mixing vessels” that generate pandemic influenza strains through genetic reassortment among avian, swine, and/or human influenza viruses. more infos
