โ€œLarge-scale, efficient testing has been proven to be a key to controlling the rampant spread of coronavirus in the global war against the pandemic,โ€ reports Caixinย (paywall). But expanding โ€œcapacity to meet massive demand for testing while improving the reliability of tests remains a challenge.โ€

Global demand for COVID-19 test kits reached 84.3 millionย as of April 17, but according to an April 20 studyย (in Chinese) by Beijing-based Dongxing Securities, โ€œonly 14.4 million tests were actually carried out globally.โ€

Although China has โ€œexpanded capacity by fast-tracking approval of dozens of testing kits, setting up new labs and authorizing more private institutions to take partโ€ and the countryโ€™s manufacturing capacity of testing kits has โ€œsurpassed 9 million a dayโ€ฆaccess to testing has been unevenโ€ฆ While big cities including Beijing, Guangdong and the epicenter Wuhan have greatly expanded capacity and allowed residents to take tests as they wish, people in remote areas such as Heilongjiang still face difficulties obtaining tests.โ€

China is now going through what much of the rest of the world will soon experience. Caixin notes, โ€œWithout proven treatments and vaccines, continued disease control measures such as social distancing and aggressive testing will be essential for countries to bring the outbreak under control.โ€
