In addition to routine blood results, myocardial enzyme profile, lung CT, and C-reactive protein should be improved.

For the new coronavirus pneumonia should strengthen the prevention and control, wear a mask when going out, wash hands regularly, pay attention to eat more fresh vegetables and fruits, do not stay up late, improve the body’s resistance.
