SARS-CoV-2 test tracker

Our interactive map uses publicly available data to show the number of SARS-CoV-2 tests that have been performed in each country, and the number of positive cases. The map was developed using open-source code initially developed by the London School of Hygiene & Tropical Medicine.

Several countries and entities including the World Bank are publishing aggregate estimates on the total number of tests performed. These reports are published across individual websites, statistical reports and press releases – often in multiple languages and updated with different periodicity. Although there is currently no centralized database and many countries do not publish official reports on volumes of tests performed, we are working to build a global picture of how many people are being tested for COVID-19.

Our map collates data from every reliable data source we can find and is being updated continually as new information becomes available.

NOTE: We have only been able to track down numbers of tests performed for 1 Chinese province so far, thus test data for China are not currently shown.

As well as continuing to hunt for data, we are also working to improve the format and functionality of the map to make it as user-friendly as possible.
