What Center for Viral Systems Biology does
Center for Viral Systems Biology (CViSB) is a multi-institutional academic research consortium founded in 2018 and led by Scripps Research under the direction of Kristian Andersen, with funding from the NIH National Institute of Allergy and Infectious Diseases (NIAID, Award U19AI135995). The consortium integrates Scripps Research, Tulane University, MIT, UCLA, the Ragon Institute of MGH/MIT/Harvard, Kenema Government Hospital, and the Sierra Leone Ministry of Health to study the genetic, immunological, and physiological factors that determine outcomes from viral infections, with primary focus on Ebola virus, Lassa virus, and SARS-CoV-2.
CViSB's core offerings center on the CViSB Data Portal (compiling data on 7,000+ Ebola patients, 6,500+ Lassa patients, 5,000+ COVID-19 patients, plus thousands of viral sequences, serology samples, and HLA sequences) and an integrated suite of open-source bioinformatics tools, including iVar for viral amplicon sequencing, Freyja for SARS-CoV-2 lineage abundance estimation in mixed samples such as wastewater, Bjorn for parallelized mutation counting, and Outbreak.info, a public-facing variant tracking platform adopted by the CDC and FDA. The technology stack extends to BEAST/BEAGLE for phylogenetic analysis and Clonify, AbStar, and AbUtils for antibody repertoire analysis, with newer AI/ML capabilities spanning ESM2, DeBERTa, LLMs, and autoencoders.
CViSB operates as a non-profit, grant-funded research consortium rather than a commercial entity. All data and software tools are released openly without restrictions, and there are no commercial products, licensing fees, or paid services. The customer base comprises academic researchers studying viral systems biology and clinical/public health entities (Kenema Government Hospital, Sierra Leone Ministry of Health) supporting field operations. Go-to-market is community-led through scientific publications, open-source software distribution, conferences, training programs, and internships, with adoption among public health agencies (CDC, FDA) serving as the primary form of validation rather than revenue.

Center for Viral Systems Biology product offering
Product offeringCore offering
The Center for Viral Systems Biology (CViSB) is a multi-institutional research consortium that conducts systems biology research on viral infections (Ebola, Lassa, SARS-CoV-2) and distributes open-source bioinformatics tools (iVar, Freyja, Bjorn, Outbreak.info) along with a public data portal containing patient and viral sequence data for the infectious disease research community.
Product overview
CViSB is a research consortium focused on understanding viral disease outcomes through systems biology approaches. The core offering is the CViSB Data Portal, which provides centralized access to patient and viral sequence data for Lassa fever, Ebola, and COVID-19 research. The product portfolio includes specialized bioinformatics tools: iVar for viral amplicon-based sequencing analysis; Freyja for SARS-CoV-2 lineage abundance estimation from wastewater; Bjorn for mutation counting from viral genomes; and Outbreak.info as a public-facing web resource for COVID-19 variant tracking. Additional tools include BEAST/RBeast for Bayesian phylogenetic analysis, BEAGLE for high-performance phylogenetic computations, Tracer for MCMC trace analysis, and antibody analysis tools (Clonify, AbStar, AbUtils). VIC Explorer and VIC Network provide specialized visualization of Ebola antibody data. These tools work together as an integrated ecosystem for viral genomics and systems immunology research, with many tools distributed via Docker containers and available through the outbreak.info API.
