AND：研究：新冠病在纸币和手机屏幕上可存活28天_COIN

澳大利亚最新研究显示，钞票、玻璃和其他常见表面上的新冠病可能在数周内一直具有传染性。这项研究强调了纸币、触屏设备、门把手和扶手传播病的风险。

A recent study in Australia shows that banknotes, glass, and other common surface new coronary diseases may remain contagious for weeks. The study highlights the risk of banknotes, tentacles, doorknobs and handrails spreading disease.

澳大利亚联邦科学与工业研究组织首席执行官拉里·马歇尔博士说：“确定病在物体表面存活的时间，使我们能够更准确地预测和减缓其传播，并更好地保护民众。”

Dr. Larry Marshall, Chief Executive Officer of the Australian Federal Scientific and Industrial Research Organization, said: “The determination of the time during which a disease survives on the surface of an object enables us to predict and slow its spread more accurately and to better protect the population”.

该研究指出，新冠病主要通过在他人附近打喷嚏或咳嗽的感染者产生的气溶胶和飞沫传播。根据这项研究，受污染的表面在病传播中的作用尚未完全确定，但“被认为是一种潜在的传播方式，因此世卫组织和国家防控措施也高度重视勤洗手的作用”。

According to the study, the role of contaminated surfaces in the transmission of the disease has not yet been fully determined, but “is considered a potential mode of transmission, so WHO and national control measures also attach great importance to hand-washing”.

新冠病可以在物体表面存活多久？

How long can new coronary disease survive on the surface of an object?

研究指出：“病在玻璃上可以存活很久是一个重要的发现，考虑到触屏设备，如手机、银行自动取款机、超市自助收银台和机场自助值机设备的触摸频率很高，可能无法定时清洁，因此会造成传播新冠病的风险。”

The study noted that “the long-term survival of the disease on the glass is an important finding, considering that the high frequency of contact with screen-touching equipment, such as mobile phones, bank ATMs, supermarket self-service cashiers and airport self-service machine equipment, may not be kept clean regularly, thus creating a risk of spreading new coronary disease”.

"Ithasbeendemonstratedthatmobilephonescanharbourpathogensresponsiblefornosocomialtransmissionand,unlikehands,arenotregularlycleaned."

“人们已经证实，手机可以藏匿病原体，导致院内传播，而且不像手可以经常清洁。”

“It has been established that mobile phones can hide pathogens, leading to intra-hospital transmission, and not as often as hands can clean.”

该组织表示，这一发现可能有助于解释新冠病在屠宰场等低温环境中持续传播的原因。

According to the organization, this discovery may help explain why the new coronary disease continues to spread in low-temperature environments such as slaughterhouses.

澳大利亚疾病防控中心主任特雷弗·德鲁说，病在宿主体外表面的存活取决于许多因素。

Trevor Drew, Director of the Australian Center for Disease Control and Prevention, said that the survival of the disease on the surface of the host depended on many factors.

"Howlongtheycansurviveandremaininfectiousdependsonthetypeofvirus,quantity,thesurface,environmentalconditionsandhowit'sdeposited–forexample,touchversusdropletsemittedbycoughing,"ProfessorDrewsaid.

德鲁教授说：“它们能存活多久并保持传染性取决于病的类型、数量、表面、环境条件以及病的沉积方式，例如，接触还是咳嗽排出的飞沫。”

Professor Drew said: “How long they survive and remain contagious depends on the type, number, surface, environmental conditions and the way the disease is deposited, such as exposure or coughing.”

"Proteinsandfatsinbodyfluidscanalsosignificantlyincreasevirussurvivaltimes."

“体液中的蛋白质和脂肪也能显著增加病的存活时间。

“Proteins and fats in body fluids can also significantly increase the survival time of the disease.
