No, just wash our hands frequently. After touching the objects contaminated by the novel coronavirus (COVID-19) and then touching eyes, mouth and nose may cause indirect contact infection. Because COVID-19 has a limited time to survive outside the human body, and in non-endemic areas, there is a low probability that items in the supermarket will be infected by the patient's mouth, so we don't need to be overly nervous.

不需要，勤洗手就可以了。手触摸到被新型冠状病毒污染的物体，再去接触眼、口、鼻，可能造成间接接触传播。因为新型冠状病毒在体外存活的时间有限，同时在非流行地区，超市里的物品被患者口沫污染的概率很低，无需过度紧张。
