Coronavirus disease 2019 (COVID-19) has taken more than a million lives worldwide and continues to proliferate in communities across the globe. The American Roentgen Ray Society (ARRS) would like to extend our sincere condolences to those whose lives have been adversely impacted by this disease and our gratitude to the global community of health care workers who have worked tirelessly to preserve the lives of so many.

The ARRS is committed to promoting sound principles that protect the health and well-being of our patients and our members. We encourage everyone to practice and promote simple evidence-based risk mitigation strategies such as hand washing, masking, and social distancing as recommended by infectious disease and epidemiology experts, who possess the necessary knowledge and experience to guide us through a pandemic. In doing so, we not only protect ourselves, but we protect vulnerable populations and alleviate the growing pressure on our health care facilities and frontline providers.

The ARRS will continue to monitor new developments pertaining to COVID-19 to provide its members with content that is relevant, timely, and based on the best available scientific evidence. In order to promote the understanding of this often-lethal disease and the associated imaging features, ARRS is providing radiologists, medical professionals, and the public at large with open access to the latest imaging research on COVID-19, as well as supporting educational content. In this way, we will fulfill our mission of improving health through a community committed to advancing knowledge and skills in radiology.
