The N3C Data Enclave is a secure portal containing a very large and extensive set of harmonized COVID-19 clinical electronic health record (EHR) data. The data can be accessed through a secure cloud Enclave hosted by NCATS and cannot be downloaded due to regulatory control. Broad access is available to investigators at institutions that sign a Data Use Agreements and via Data Use Requests by investigators. The N3C is a unique open, reproducible, transparent, collaborative team science initiative to leverage sensitive clinical data to expedite COVID-19 discoveries and improve health outcomes.
This resource allows users to search for and compare influenza virus genomes and gene sequences taken from GenBank. It also provides a virus sequence annotation tool and links to other influenza resources: NIAID project, JCVI Flu, Influenza research database, CDC Flu, Vaccine Selection and WHO Flu. NOTE: In Fall 2024, NCBI plans to redirect the Influenza Virus Resource to NCBI Virus, possibly as soon as September. For most up-to-date and accurate virus data, see NCBI Virus https://www.re3data.org/repository/r3d100014322
<<<!!!<<< Effective May 2024, Virus Variation will no longer be available and will be redirected to NCBI Virus https://www.ncbi.nlm.nih.gov/labs/virus/vssi/#/ >>>!!!>>> NCBI Virus Variation is a specialized database which collects tools to provide searchable resources in the fields of Influenza virus, Dengue virus, and West Nile virus. Specific BLAST databases are listed. Their new publications are also available in their site. Rotavirus database will be added in their site soon.
