Since November 2019, the novel coronavirus known as SARS-CoV-2 (formerly, 2019-nCoV) has devastated communities and overwhelmed healthcare facilities worldwide. Research on the virus, its epidemiology, modes of infection, and potential treatments has been rapid, providing new insights to guide both clinical practice and public health recommendations each day.
The ability to share discoveries quickly is at the heart of the preprint mission, and facilitating it has been central to the ethos of Research Square since its founding. At no time is this goal more salient or pressing than in times of public health emergencies. Here, we aim to provide the most recent Research Square preprints relevant to the COVID-19 outbreak and its wide-ranging effects on the global community. All content posted here is free to read and download, and we encourage readers to engage via comments and annotations.
