Global Research on Coronavirus Disease (COVID-19)
WHO is gathering the latest international multilingual scientific findings and knowledge on COVID-19. The global literature cited in the WHO COVID-19 database is updated daily (Monday through Friday) from searches of bibliographic databases, hand searching, and the addition of other expert-referred scientific articles.
This database represents a comprehensive multilingual source of current literature on the topic. While it may not be exhaustive, new research is added regularly.
