Scientists from the Australian national research agency CSIRO set out to see how the novel coronavirus fares in terms of persistence on surfaces compared to the flu virus.
From the mouth of the so-called Coronersceptics can often hear that Covid-19 is actually a slightly different flu, and the whole pandemic has been blown up too much. Scientists, who have been in contact with the SARS-CoV-2 virus for several long months, prove with each passing day that although the symptoms may be similar, we are dealing with two different diseases, and in many respects. And the latest research provides information on how long viruses last on different surfaces and under different conditions, suggesting that things like cold, glass, stainless steel and banknotes significantly extend the life of the virus that causes Covid-19, which defeats the flu virus by a full 10 days . CSIRO researchers found that on some common surfaces, such as banknotes and smartphone displays, the SARS-CoV-2 virus can survive up to 28 days, and their tests at the Australian Center for Disease Preparedness (ACDP) can be summarized as follows - the virus :
- lives longer in low temperatures,
lives longer in low temperatures,
- lives longer on non-porous smooth surfaces such as glass, stainless steel and vinyl compared to porous surfaces such as cotton
lives longer on non-porous smooth surfaces such as glass, stainless steel and vinyl compared to porous surfaces such as cotton
- lives longer on paper notes than on plastic ones.

CSIRO's chief executive, Dr. Larry Marshall, says virus survival research builds on the agency's work to date on Covid-19, such as testing vaccines, waste water, conservation measures, and more. - Determining how long the virus remains active on different surfaces allows us to more accurately predict and prevent its spread, that is, to better protect our citizens - he explains. Dr Debbie Eagles, working both on better understanding the virus and testing potential vaccines, adds: `` Our results show that SARS-CoV-2 remains contagious on surfaces for a very long time, a reminder of good practices like regular washing hands and frequently used surfaces. At 20 ℃, or around room temperature, the virus remains extremely potent, surviving 28 days on smooth surfaces such as glass on displays or plastic banknotes. For comparison, the influenza A virus survives 17 days under similar conditions, which shows how strong and resistant SARS-CoV-2 is.
Scientists used a concentration of the virus torrent websites directory to that observed in samples from infected patients, and after testing at room temperature, they switched to those at 30 and 40 ℃, which, as you can easily guess, negatively affected the virus's survival ability. Researchers also focused on conducting a study in the dark to rule out the influence of UV radiation, because, as shown by other tests, it can instantly deactivate the coronavirus. As Dr. Eagles adds, although we still do not know exactly what role surface transmission plays, it is useful to know how long the virus is dangerous on frequently used surfaces to know how to possibly protect yourself from infection in this way.
