It is all about "test", says expert on fighting COVID-19

"Test, test and test," said Du Bin, a leading Chinese heath expert fighting COVID-19, on the measures to control the epidemic. The test refers to the nucleic acid test, he said, and whenever there is no opportunity to test, you never know who is the carrier or patient. Du made the remarks at a news conference on Monday.

The turning point of the outbreak in Wuhan was to isolate all suspected patients and close contacts.
