COVID-19 Glossary

WIPO Pearl was updated in 2020 with 147 key concepts related to the COVID-19 pandemic. These key concepts are provided in the 10 languages of the database and comprise in total 1,500 terms. The aim is to help provide consistency and clarity across different languages regarding key terminology of the COVID-19 pandemic. These COVID-19 terms are also available in a separate glossary which contains links to the Full Record in WIPO Pearl for each concept, where definitions, multilingual equivalents, contexts, and concept maps can be found. The glossary is also linked to PATENTSCOPE, allowing any patents containing these terms to be easily located. Finally, this collection of COVID-19 terms is available for download from the glossary.
