The Center for Infectious Disease Dynamics (CIDD) at Penn State University is comprised of more than 50 faculty experts in infectious disease. We want to help you get scientifically informed, up to date answers to your questions about the pandemic.
Please send your questions about COVID-19 to the email address above.
New questions, including a number of topics not covered by our video series, are answered weekly at our COVID-19 Q&A page. To keep up with the latest answers to public questions, please bookmark this page.
Each Monday, one of these questions is answered via video as well. Links to these videos are provided below. You can subscribe to our YouTube playlist here.

The information we’re generating in our research will help in designing better therapeutics and better vaccines.

At CIDD, we study infections from the perspective of the parasitic agent. Our faculty and research span human, animal, and plant systems to determine the unique demands of the parasitic lifestyle, the responses of the hosts and how the environment affects these interactions.
This approach yields novel insights into the biological processes that drive the biology and evolution of infectious agents, and the processes that can be used to limit their harm to individual and population health.
