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.

　　一項研究模擬了SARS患者在快遞包裹上打噴嚏的情況:準備一種病毒濃度接近患者鼻咽分泌物的液體，取一個相當于大的呼吸液滴(5 l，半徑1mm)的東西，把它滴在紙上和塑料上。

　　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.

　　在紙干后(約5分鐘)，SARS病毒的感染能力消失，但在塑料上停留一個小時。如果病毒濃度增加100倍，病毒可以在紙上存活24小時，在塑料上存活兩天。在另一項研究中，SARS病毒在木材和土壤中的存活時間明顯短于玻璃和金屬等材料。結果，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，與防水織物相比，吸水性棉質衣物的病毒存活時間也明顯縮短。

　　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、陶瓷和一般金屬材料與塑料相似，SARS病毒濃度較高，可在室溫下在物體表面生存4~6天，但金屬表面的高銅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.

　　也就是說，如果冠狀病毒患者未戴口罩而在塑料袋或其他塑料制品上打噴嚏，那么附著有患者飛沫的塑料袋或其他塑料制品可能在一定時間內被感染。一個正常的塑料袋或其他塑料制品是不可能在正常情況下，因為冠狀病毒只感染脊椎動物，如人類，老鼠，豬，貓，狗，狼，雞，牛，和家禽，并不能長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.

　　但無論何種材料，服用后避免接觸眼睛、口鼻和洗手，都能有效避免新型冠狀病毒感染。所以小編,我們只要主動保護,為了保護自己,戴上面具,洗手,不要/少去很多人的地方,不追隨別人,傳播謠言,相信很快就會過去,感謝所有前線醫務人員。

　　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.
