Are there coronaviruses in plastic bags? Plastic bags, plastic films, plastic bags, one of the necessities of our daily life, will there be coronaviruses in plastic bags? Although the research results on the survival time (the ability to keep infectious) of new coronaviruses need to be supplemented, we can infer from the characteristics of other coronaviruses, such as the famous SARS.

　　一项研究模拟了SARS患者在快递包裹上打喷嚏的情况:准备一种病毒浓度接近患者鼻咽分泌物的液体，取一个相当于大的呼吸液滴(5 l，半径1mm)的东西，把它滴在纸上和塑料上。

　　A study mimics how SARS patients sneeze on express packages: prepare a liquid with a virus concentration close to the patient's nasopharynx secretion, take a large breath drop (5 L, 1 mm radius) and drop it on paper and plastic.

　　在纸干后(约5分钟)，SARS病毒的感染能力消失，但在塑料上停留一个小时。如果病毒浓度增加100倍，病毒可以在纸上存活24小时，在塑料上存活两天。在另一项研究中，SARS病毒在木材和土壤中的存活时间明显短于玻璃和金属等材料。结果，SARS病毒失去了在吸水材料表面比在防水材料表面更快感染的能力。在衣物方面，与防水织物相比，吸水性棉质衣物的病毒存活时间也明显缩短。

　　After the paper dried (about 5 minutes), the infection ability of SARS virus disappeared, but remained on the plastic for one hour. If the concentration of the virus increased 100 fold, the virus could survive on paper for 24 hours and on plastic for two days. In another study, the survival time of SARS virus in wood and soil was significantly shorter than that in materials such as glass and metal. As a result, the SARS virus lost its ability to infect water absorbent surfaces faster than waterproof surfaces. In terms of clothing, compared with waterproof fabric, the virus survival time of absorbent cotton clothing is also significantly shorter.

　　玻璃、陶瓷和一般金属材料与塑料相似，SARS病毒浓度较高，可在室温下在物体表面生存4~6天，但金属表面的高铜含量不利于病毒的生存。

　　Glass, ceramics and general metal materials are similar to plastics. SARS virus has a high concentration and can survive on the surface of the object for 4-6 days at room temperature, but the high copper content on the metal surface is not conducive to the survival of the virus.

　　也就是说，如果冠状病毒患者未戴口罩而在塑料袋或其他塑料制品上打喷嚏，那么附着有患者飞沫的塑料袋或其他塑料制品可能在一定时间内被感染。一个正常的塑料袋或其他塑料制品是不可能在正常情况下，因为冠状病毒只感染脊椎动物，如人类，老鼠，猪，猫，，狼，鸡，牛，和家禽，并不能长期生存在塑料袋或其他塑料制品。

　　In other words, if a person with coronavirus sneezes on a plastic bag or other plastic product without wearing a mask, the plastic bag or other plastic product attached with the patient's droplets may be infected within a certain period of time. A normal plastic bag or other plastic product is impossible under normal circumstances, because the coronavirus only infects vertebrates, such as humans, mice, pigs, cats, dogs, wolves, chickens, cattle, and poultry, and cannot live in plastic bags or other plastic products for a long time.

　　但无论何种材料，服用后避免接触眼睛、口鼻和洗手，都能有效避免新型冠状病毒感染。所以小编,我们只要主动保护,为了保护自己,戴上面具,洗手,不要/少去很多人的地方,不追随别人,传播谣言,相信很快就会过去,感谢所有前线医务人员。

　　However, novel coronavirus infection can be effectively avoided by avoiding contact with eyes, nose and mouth and hands after taking any material. So Xiaobian, we just need to take the initiative to protect ourselves, put on masks, wash our hands, don't / don't go to many people's places, don't follow others, spread rumors, believe it will pass soon, thank all the front-line medical staff.
