The virus tracker, compiled by China’s National University of Defense Technology and leaked to Foreign Policy magazine, appears to confirm fears that the nation’s Communist government is hiding the true nature of the outbreak which originated in Wuhan late last year.

According to the report, the virus tracker consists of more than 640,000 rows of cases in 230 cities ranging from early February to late April and confirms the location of each infection.

The data includes locations for hospitals, train stations, hotels, restaurants and schools and was compiled by a professor at the university which is run by China’s Central Military Commission, the report said.
