Resumen
Our understanding of the evolution of the COVID-19 pandemic is built upon data concerning confrmed
cases and deaths. This data, however, can only be meaningfully interpreted alongside an accurate
understanding of the extent of virus testing in diferent countries. This new database brings together
ofcial data on the extent of PCR testing over time for 94 countries. We provide a time series for the
daily number of tests performed, or people tested, together with metadata describing data quality and
comparability issues needed for the interpretation of the time series. The database is updated regularly
through a combination of automated scraping and manual collection and verifcation, and is entirely
replicable, with sources provided for each observation. In providing accessible cross-country data on
testing output, it aims to facilitate the incorporation of this crucial information into epidemiological
studies, as well as track a key component of countries’ responses to COVID-19.
