There, as recently as May 2, the state averaged nearly 3,500 cases a day, according to a June 2 story in \u003Ca href=\u0022https:\/\/www.bridgemi.com\/michigan-health-watch\/coronavirus-tracker-what-michigan-needs-know-now\u0022\u003EBridge Michigan\u003C\/a\u003E.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAccording to one scenario from the simulation, which was populated with data from the state of North Carolina, if 75% of the population gets fully vaccinated but continues to wear masks and socially distance,\u0026nbsp; there is a sustained decline down to very few new Covid-19 cases over a six-month period.\u0026nbsp; But, if only 25% of the population gets fully vaccinated and does not adhere to these non-pharmaceutical interventions (NPIs), there could be a steady increase in daily Covid-19 cases, peaking around 8,000 before there is another decline.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EKeskinocak points to the \u003Ca href=\u0022https:\/\/chhs-gt.shinyapps.io\/georgiavaccines\/\u0022\u003EGeorgia Covid-19 Vaccination Dashboard\u003C\/a\u003E that tracks county-level differences in vaccination rates based on race as further evidence of the need for caution.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Our dashboard shows that there has been high variability in the level of vaccination in different geographic regions and communities,\u0026rdquo; she said. \u0026ldquo;So even if we say over half of U.S. adults are vaccinated, it\u0026rsquo;s not uniform across the entire country.

It also increases the chance of a future mutation that could increase the risk even to people who are vaccinated.\u0026rdquo;\u0026nbsp;\u003Cbr \/\u003E\r\nSwann and Keskinocak are two of three researchers who co-founded Georgia Tech\u0026rsquo;s Center for Health and Humanitarian Systems in 2007, the year they developed a comprehensive, agent-based simulation model for pandemic flu, which has since been at the core of their modeling efforts for Covid-19. Over the years the two industrial engineers have collaborated closely to advance the model and make results available to decision makers as new pandemics emerged.\u0026nbsp; \u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Julie and I have been working on infectious disease modeling for over a decade now. We had developed this agent-based model for pandemic flu and then when Covid-19 hit, Georgia Tech adapted that model to Covid-19 and shared it with Julie\u0026rsquo;s team at NC State who then modified the model to test additional scenarios and calibrated it with North Carolina data,\u0026rdquo; Keskinocak said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;I am grateful that Pinar and I had spent such a long time trying to understand pandemics and improving the science behind them,\u0026rdquo; Swann added. \u0026ldquo;If we had not invested that time, we would not be able to have such a fast turnaround and the high participation level that we have this year.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAccording to Keskinocak, the simulation model is extremely detailed \u0026ndash; in essence, it recreated demographics of the population down to the state\u0026rsquo;s household size, and even individuals\u0026rsquo; workflow, to give a clear picture of how people move from one geographic area to another.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026ldquo;The model is flexible and can change based on the research question being asked, including the current research question, \u0026lsquo;What is the impact of lifting NPIs in increasing vaccine coverage?\u0026rsquo;\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESwann credited the close partnership with public health partners in Georgia and North Carolina, as well as their work under a grant funded by the Centers for Disease Control and Prevention and the Council for State and Territorial Epidemiologists, with the speed of developing models to test interventions during the pandemic.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;It\u0026rsquo;s really key because sometimes we get additional ideas or research questions from the stakeholders with whom we interact,\u0026rdquo; Swann said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBoth researchers emphasized the critical role students played in advancing these models under tight deadlines while juggling coursework. Between them they estimate more than two dozen graduate students across the partnering institutions have been engaged in the Covid-19 modeling work since the pandemic began.
