About Us

The Johns Hopkins Coronavirus Resource Center (CRC) is a continuously updated source of COVID-19 data and expert guidance. We collect and analyze the best data available on cases, deaths, tests, hospitalizations, and vaccines to help the public, policymakers, and healthcare professionals worldwide respond to the pandemic. TIME recognized the CRC as the “go-to data source” for COVID-19 and named it to the Top 100 Inventions of 2020. In 2021, Research!America named the CRC a recipient of its “Meeting the Moment for Public Health” award.

The CRC is supported by Bloomberg Philanthropies and the Stavros Niarchos Foundation.

To receive the latest expert analysis every Monday on vaccinations, cases, deaths, hospitalizations, and more, please subscribe to the Coronavirus Resource Center's The Week in COVID-19 email newsletter.


The COVID-19 Testing Insights Initiative

The COVID-19 Testing Insights Initiative, part of the CRC, reflects an interdisciplinary collaboration between several groups at Johns Hopkins University: The Johns Hopkins Bloomberg School of Public Health, Applied Physics Laboratory, Center for Systems Science and Engineering (CSSE) in the Whiting School of Engineering, and the Centers for Civic Impact.

CRC Experts

Johns Hopkins Bloomberg School of Public Health:

  • Dr. Bill Moss, CRC vaccinology lead, is Executive Director of the International Vaccine Access Center and Professor in the Departments of Epidemiology, International Health and Molecular Microbiology and Immunology.
  • Dr. Crystal Watson, CRC Public Health Lead lead, is an Assistant Professor in the Department of Environmental Health and Engineering and a Senior Scholar at the Center for Health security.
  • Dr. Lainie Rutkow, CRC project lead, is a Professor of Health Policy and Management and Senior Adviser to President Ronald Daniels.

Johns Hopkins Medicine:

  • Dr. Brian Garibaldi, CRC clinical lead, is Medical Director of the Johns Hopkins Biocontainment Unit and is an Associate Professor of Medicine with expertise in pulmonary and critical care medicine, Acute Lung Injury, and Interstitial Lung Disease.

Centers for Civic Impact (CCI), Krieger School of Arts and Sciences:

  • Beth Blauer, CRC data lead, is the Associate Vice Provost for Public Sector Innovation at Johns Hopkins and oversees the Bloomberg Center for Government Excellence and the Bloomberg Center for Public Innovation, both supported by the Bloomberg Philanthropies. Working in collaboration with data scientists and public health experts, Blauer and her team transform raw COVID-19 data into clear and compelling visualizations that help policymakers and the public understand the pandemic and make evidence-based decisions about health and safety.

Center for Systems Science and Engineering (CSSE), Whiting School of Engineering:

  • Dr. Lauren Gardner and her team at the CSSE built the COVID-19 global tracking map in January 2020, creating the most comprehensive publicly available data set on the pandemic. Dr. Gardner’s data drives much of the CRC’s analysis and serves as a vital resource for millions of users to track the pandemic.

Applied Physics Laboratory:

A team of data scientists and engineers from APL – the nation’s largest university-affiliated research center – build and maintain the CRC’s data infrastructure. The APL team sources information from the global to the local levels and builds the data pipelines that are the project’s backbone. The complex, comprehensive datasets the team acquires supply all of the CRC’s visualizations and analyses with constantly updated information from around the world.

About Our Sources:

Since the pandemic began, Johns Hopkins experts have collecting and analyzing domestic and international data about COVID-19. The effort began on Jan. 22, 2020 with one of the first global maps to track Covid-19 cases and deaths. It evolved on March 3, 2020 into the Johns Hopkins Coronavirus Resource Center. The CRC’s more than 260 sources include 182 from local, state, and federal agencies in the United States.

  • Dr. Jennifer Nuzzo, a former Senior Scholar at the Johns Hopkins Center for Health Security, was the CRC epidemiology lead from spring 2020 through March 2022. She spearheaded the development and implementation of the CRC’s Testing Insights Initiative before departing in April 2022 for a position at Brown University.
