A member asked:

Good day; can the test for the novel corona virus detect the virus during the incubation period in asymptotic patients? i would like to return to sa from china (not from the region where the outbreak occurred) and get tested immediately

Maybe. Maybe not.: Annually, China had ~60 million foreign tourists before the outbreak and ~130 million Chinese traveled out of China. That's half a million people leaving China every day. Even though that's mostly come to a halt, we do not have the ability to test all persons leaving China. Testing must be more selective. Also, testing people who do not have contact with the virus leads to false positives, etc...
