The new coronavirus can survive 28 days on smooth surfaces

  Science and Technology Daily, Beijing, October 12 (intern reporter Lu Zijian) According to the official website of the Australian Commonwealth Scientific and Industrial Research Organization, an experiment conducted by its researchers at the Australian Centers for Disease Prevention showed that the new crown virus is at low temperature and non-porous surfaces or smooth Survival time is longer on surfaces (such as glass, stainless steel, vinyl plastic).

At 20°C, the new coronavirus can survive for up to 28 days on common surfaces such as banknotes, glass (such as mobile phone screens) and stainless steel.

The research results were published in the recent "Journal of Virology."

  Dr. Debbie Eagles, deputy director of the Australian Centers for Disease Prevention, said that by comparison, the influenza A virus can only survive for 17 days in similar experiments.

This also proves the tenacious vitality of the new crown virus.

"Our results show that the new coronavirus can remain infectious on the surface of objects 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.

  Dr. Iggs said that although the exact role of surface transmission, the degree of surface contact, and the number of viruses required for infection in the spread of the virus have not yet been determined, for the development of risk mitigation strategies in high-contact areas, it is How long the surface can survive is important.

  Dr. Larry Marshall, Chief Executive Officer of the Australian Commonwealth Scientific and Industrial Research Organization, said, “Determining how long the new coronavirus can survive on the surface of an object can enable us to more accurately predict and slow its spread, and better protect the population.

  In addition, the researchers also conducted further experiments at 30°C and 40°C and found that the survival time of the new coronavirus decreased with the increase in temperature.
