To prevent the new coronavirus, first of all, avoid going out, partying, and going to areas with heavy traffic and high incidence of the epidemic. Always wear a mask when going out and wear it correctly and reasonably. Cover up with paper or elbow when sneezing or coughing, do not cover directly with your hands. Do wash your hands regularly, using running water or soap, hand sanitizer containing alcohol. Drugs and vaccines for the new coronavirus are still in development, but further clinical trials are needed. The current focus is on symptomatic and supportive care to prevent further exacerbation of the patient’s condition.
