Currently, most patients with novel coronavirus pneumonia are diabetic, hypertensive or obese, and some have fatty liver, chronic liver and kidney disease, and chronic lung disease (including asthma), so these patients need to be more vigilant.
In addition, the elderly are also susceptible to and at high risk for novel coronavirus pneumonia, which is relatively difficult to cure and recover from, so they should go out as little as possible and travel less by public transportation.
