Viral Infection and Respiratory Illness Universal Study (VIRUS) is a prospective, cross-sectional, observational study and registry of all eligible adult and pediatric patients who are admitted to a hospital. There is no intervention or patient interaction. Only de-identified data are used for analysis.
ClinicalTrials.gov Identifier: NCT04323787

The registry will be essential for near-real-time observational comparative effectiveness studies to determine effective treatment strategies and/or provide meaningful hypotheses for clinical trials.
A waiver of informed consent for data collection is being requested for this study from participating sites. No patients will be contacted, but clinicians participating in the study will be surveyed for feedback and satisfaction. For any questions, contact Vishakha Kumar.

Submission process: Ancillary study proposals may be submitted for a subset of de-identified data for research purposes by investigators of participating sites in the VIRUS study. Proposals are submitted via an online submission portal. Submitted proposals are reviewed by the Discovery VIRUS Publication Review Workgroup for approval and feedback.
Datasets may be made available to outside groups (nonparticipating sites and investigators) after initial publication of the data by study principal investigators within 12 months of study conclusion. A Data Use Agreement must be in place for this type of request.
Review Process: The Discovery VIRUS Publication Review Workgroup will assign two to three reviewers per proposal. The timeline for approval is up to 30 days.
The proposal submission portal is now open. Access the submission portal.
Feedback on proposals will be shared with investigators. The Discovery VIRUS Publication Review Workgroup makes rapid review of proposals a priority. Once approved, investigators receive access to the de-identified subset of data from the VIRUS dataset.
