But yes it does indicate that the real number is much higher than the confirmed cases. It's really hard to track an outbreak of this magnitude especially when many people are carriers showing mild symptoms. It's actually a good thing if cases are being severely underestimated as it implies a lower death rate (deaths are harder to fudge).
Are you sure about this? AFAIK, the Chinese government does not disclose someone as dead by this virus unless they tested the person positive. That means that if someone dies from respiratory complications on the street or in their home, they will write it off as pneumonia. Right now Wuhan city only has the capacity to screen roughly 6000 samples everyday. Add to this that many sick people are basically just told to go home. Not many cars are driving, city is shutdown so god knows how many are sitting lifeless in their livingroom. I have also seen much evidence that communities are barring the doors of infected households so they can't leave their apartments.
The death count can only be expected considerably higher than reported.
Best wishes for your recovery!
