The 9th case of coronavirus in the US, the likely hood that this might get out of control in the US is also possible. One thing to highlight here is the 2 different approaches to how 2 people in the US approached the virus in this article. One which is a Wuhan local did not sought medical attention immediately while the other did though we have no information regarding his nationality.
This is not so say that every single Chinese are doing this, but it does goes to show how public health awareness plays a great role in containing outbreaks.
It reminds me of the meme of Chinese attributing every single symptom of sickness as being curable by "drinking more water". My advice would be even if it seems like a normal flu, go see a doctor as soon as possible.
