The National COVID Cohort Collaborative (N3C)

The N3C Data Enclave is a secure platform through which harmonized clinical data provided by our contributing members are stored. The Enclave includes demographic and clinical characteristics of patients who have been tested for or diagnosed with COVID-19, and further information about the strategies and outcomes of treatments for those suspected or confirmed to have the virus. Additional data from individuals infected with pathogens such as SARS 1, MERS, and H1N1 are also included to support comparative studies. For more information on the inclusion and exclusion criteria, see the N3C Phenotype. To view a full list of data elements, click here. Data are updated from contributing sites at an average interval of twice a week.
