New Coronavirus “28 Days of Infectious Power on the Surface of Banknotes” Australian Agency October 12 17:28
An Australian government research institute has released research results that the new coronavirus exists in an infectious state for at least 28 days on surfaces such as banknotes and glass under certain limited conditions, such as when temperatures are 20 degrees and dark. This research institute points out that thorough hand washing is important.
The CSIRO-Australian Federal Scientific and Industrial Research Organization conducted an experiment to see how long the new coronavirus on the surface of a common thing remains in a dark environment with a humidity of 50%.
They found that if the temperature was 20 degrees, the virus would be in an infectious state for at least 28 days on the surface of the bill or glass.
In addition, if the temperature is 30 degrees, the virus was present in an infectious state for 21 days for banknotes, 7 days for stainless steel and glass, and 3 days for cotton.
On the other hand, if the temperature is raised to 40 degrees, the infectious virus will not be detected in cotton in less than 16 hours, and the period of detection in banknotes, glass, etc. is now 24 hours.
As for the period during which the virus remains infectious, the World Health Organization has expressed a different view from the results of the study, with up to 72 hours on plastic and stainless steel surfaces, less than 4 hours on copper, and less than 24 hours on cardboard. The lower the temperature, the longer it has been.”
CSIRO points out that in addition to hand washing, measures such as keeping the surface of glass and other materials clean are important.
