Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a standardized protocol for the rapid, coordinated clinical investigation of severe or potentially severe acute infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Participants with acute illness suspected to be caused by SARS-CoV-2 (COVID-19) will be enrolled. This protocol has been designed to enable data and biological samples to be prospectively collected and shared rapidly in a globally-harmonized sampling schedule. Multiple independent studies can be easily aggregated, tabulated and analyzed across many different settings globally. The protocol is the product of many years of discussion among international investigators from a wide range of scientific and medical. Recruitment under this protocol has been initiated in response to Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV) in 2012-2013, Influenza H7N9 in 2013, viral hemorrhagic fever (Ebolavirus) in 2014, Monkeypox \& MERS-coronavirus in 2018, Tick-borne encephalitis virus (TBEV) in 2019 and COVID-19 in 2020. Participants may be newly identified through healthcare system or public health access, under quarantine, or in isolation care in outpatient or inpatient settings relevant to the Johns Hopkins University School of Medicine. Other locations may adopt this study concurrently, under a deferred review, or cooperatively. The existence of this protocol would ensure a timely, comprehensive epidemiologic and clinical characterization of the initial cases of COVID-19 in a mounting pandemic. The World Health Organization (WHO) recognized the need for standardized data collection for the epidemiology, immunology and clinical characteristics of these novel pathogens, and established the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) network in 2011. At the core of the protocol are a standardized schedule, structure and content of clinical, laboratory and microbiologic data collection, supplemented by domain-specific components (e.g., acute respiratory infection, viral hemorrhagic fever). The timepoints of this protocol will also be aligned with a separate multi-center institutional review board (IRB) approved protocol to describe patients with emerging infectious diseases that present to military treatment facilities within the United States.
