Inquiring minds are good. Citizens as well as researchers pose many questions about COVID, the infection, immunity, prevention measures, treatment and long-term effects. For many of the questions, there are, as yet, no answers or incomplete answers. Guidance continues to evolve as specialists learn more.

The Mayo Clinic News Network follows developments closely and provides evidence-based information as it becomes available. Please see the COVID news section https://newsnetwork.mayoclinic.org/category/covid-19/
