A new report details that China purchased a massive amount of testing equipment for viruses like COVID-19 months before the WHO filed official reports of the outbreak in December 2019. The testing equipment in question is what is known as a PCR test or polymerase chain reaction test. These tests can be used to detect viruses in humans or animals.

According to the Sydney Morning Herald, spending for the tests soared in China’s Hubei Province—where Wuhan is located—months before the official outbreak in December 2019.  A U.S.-Australian cybersecurity firm known as Internet 2.0 compiled data points of the PCR equipment purchases into a report.

The report indicates that spending for PCR tests jumped in China from 36.7 million yuan in 2018 to 67.4 million yuan in 2019. The report also details that “notable, significant and abnormal” purchases of PCR equipment were made in 2019 “in Wuhan by the People’s Liberation Army Airborne Army Hospital (May 2019), The Wuhan Institute of Virology (November 2019), the Wuhan University of Science and Technology (October 2019) and the Hubei Province Districts Centres for Disease Control and Prevention (May-Dec 2019)”
