About CovidCasesData.com

We aggregate, compare, check and process COVID-19 data from:

  1. WHO Coronavirus disease (COVID-2019) situation reports
  2. Johns Hopkins Coronavirus Resource Center
  3. Wikipedia 2019–2020 coronavirus pandemic data template
  4. CDC Cases of Coronavirus Disease (COVID-19) in the U.S.

Some countries don't provide information on active and recovered cases, but serving zeroes will lead to incorrect calculation of world statistics (active cases will constantly grow and won't reflect the real situation). We calculate active and recovered cases for these countries based on data from studies of the course of coronavirus infection:
