This is a major accomplishment, if true. The U.S. CDC also developed a test, last week, and I have heard nothing about it since. They said at the time that it would take a couple of weeks before the test was widely available.
Hong Kong has also developed a test.
Testing is obviously a big deal. Once a test is generally available, a major benefit will be help making an accurate initial diagnosis. The official list of symptoms is so generic that identification of people with the disease is very difficult.
