The new coronavirus survives on a smooth surface for 28 days

BEIJING, Oct. 12 (Xinhua Lu Zijian) According to the official website of the Australian Federal Scientific and Industrial Research Organization, researchers at the Australian Centers for Disease Control and Prevention have shown that the new coronavirus survives longer on cryogenic and non-porous surfaces or smooth surfaces such as glass, stainless steel and vinyl. At 20 degrees C, the new coronavirus can survive for up to 28 days on common surfaces such as banknotes, glass (e.g. cell phone screens) and stainless steel. The findings were published recently in the Journal of Virology.
, deputy director of the Australian Centre for Disease Control and Prevention, said the influenza A virus survived only 17 days in similar trials. This also proves the tenacious vitality of the new coronavirus. "Our results show that the new coronavirus can remain infectious on the surface of an object for a long time. This requires strengthening the cultivation of good habits such as regular hand washing and cleaning the surface of objects. Dr. Iggs said.
Iggs said that while the exact role of surface transmission, the degree of surface exposure and the number of viruses needed to be infected during virus transmission have not yet been determined, it is important to determine how long the new coronavirus can survive on the surface of an object in a risk mitigation strategy in high-contact areas.
Dr Larry Marshall, chief executive of the Australian Federal Scientific and Industrial Research Organisation, said: "Determining how long the new coronavirus will survive on the surface of an object allows us to more accurately predict and slow its spread and better protect populations. In
, the researchers conducted further experiments at 30 and 40 degrees Celsius and found that the survival time of the new coronavirus decreased as temperatures increased.
