Not sure why the CDC says "new coronavirus". Birx used the phrase, "influenza-like" at the press conference yesterday.
"About a third of coronavirus cases are asymptomatic, the Centers for Disease Control and Prevention said in guidance for mathematical modelers and public health officials. The "current best estimate" for the percent of positive cases that are asymptomatic is 35%, but the CDC says that number could change as more data becomes available.
The CDC says the new coronavirus can be transmitted by people who have not yet experienced symptoms or who never experience symtoms."

"“Influenza-like illness” (ILI), also called “flu-like illness,” is a more wide-ranging category. The CDC says that with ILI, you have a fever of at least 100 F and a cough or sore throat, but the cause of the symptoms isn’t known.
The flu is diagnosed from a swab test of your nose or throat. Flu-like illness is a clinical diagnosis, meaning it doesn’t involve an official test. A doctor simply decides by examining you."
