To our users Please note that the HCV database site is no longer funded. We try to keep the database updated and the tools running, but unfortunately, we cannot guarantee we can provide help for using this site. Data won't be manually curated either.
Note: The new recommendations for HCV nomenclature have been published here. A summary of the new system is here.
