The problem there's very little testing being done for this novel pathogen.
New tests can't just be created by hospitals and labs out of thin air, and they can't be used without undergoing a lengthy bureaucratic approval process.
For a novel pathogen like this the tests are still in the early phases of being manufactured and approved, so most people who go in with symptoms just aren't going to be tested.
There's also a manpower issue that has to be taken in to account: if everyone with flu-like symptoms came in to get tested the hospitals and labs would be overwhelmed even if they had enough tests available and those tests were already approved. Many labs and hospitals are already close to being overwhelmed from seasonal flu.
So I really wouldn't consider official data to be very reliable at this point. We really need to wait and see.
Meanwhile, though, it would be prudent to err on the side of caution.
