Wearing face coverings, practicing social distancing, washing hands, and shuttering schools and stores. These are some of the measures that have been implemented to protect people from catching the virus responsible for COVID-19. But just how effective have these interventions been? • Engineers at Carnegie Mellon and Princeton believe they have developed a mathematical modeling approach that could tell us. Their project, called “Modeling and Control of COVID-19 Propagation for Assessing and Optimizing Intervention Policies,” looks at various factors that can impact the spread of the SARS-CoV-2 virus, including virus mutations as well as preventive measures such as wearing masks. • H. Vincent Poor, an IEEE Life Fellow, is the principal investigator of the team. Also on the team are IEEE Senior Member Osman Yağan, an associate research professor of electrical and computer engineering at Carnegie Mellon, and mathematical biologists from Princeton and the University of Pennsylvania who study viral spread. • The model recently received a grant from the C3.ai Digital Transformation Institute, a new research consortium funding projects that could reduce the effects of pandemics. Related projects on viral spread by Osman and Poor are also being funded by the U.S. Army Research Office and the United States' National Science Foundation. • The template for the new model was adapted from a mathematical theory the researchers developed in 2019 that investigated the process by which viruses and their mutations spread. In their paper, published in March in the Proceedings of the National Academy of Sciences, they compared how a virus spreads and mutates to how information changes as it's circulated by networks of people.

Here?s what we know for sure. On the afternoon of Friday, 3 October 2014, Pyrros A. Telionis got a telephone call from the U.S. government?s Defense Threat Reduction Agency (DTRA). He was sitting in a featureless cubicle in Blacksburg, Va., that would have made the cartoon office drudge Dilbert feel right at home. The voice on the phone was brisk and professional. And highly specific. Could Telionis provide, by 8 o?clock Monday morning, a list of the best places to build Ebola treatment centers in Liberia?s six southernmost counties? [ABSTRACT FROM PUBLISHER]
