A new study reveals that the coronavirus is extremely robust. The Sars-CoV-2 pathogen can remain on smooth surfaces for almost a month; this also includes everyday objects like smartphones and banknotes. One factor has a decisive influence on the survival time of the virus.
According to new Australian research, the corona virus can survive up to 28 days on smooth surfaces such as mobile phone screens or ATMs, and therefore longer than previously assumed. This is the result of a study by Australian scientific authority Csiro, which was published in the “Virology Journal”.
“At 20 degrees Celsius, around room temperature, we found the virus to be extremely robust and could survive for 28 days on smooth surfaces such as glass on cell phone screens and plastic banknotes,” said Debbie Eagles, deputy director. from the Center for Disease Prevention. carried out the investigation. The experiment was carried out in the dark; Research has already shown that sunlight can kill the virus quickly, he said.
In previous studies, the virus could only be detected on plastic and stainless steel surfaces for up to three days. Similar experiments for influenza A would have shown that this virus survived on surfaces for 17 days. That shows how resistant the corona virus is.
According to the Federal Institute for Risk Assessment (BfR), however, so far there have been no cases in which it has been proven that the coronavirus has been transmitted to people by contact with contaminated objects or by contaminated surfaces and that infections have occurred. However, according to information, smear infections through surfaces previously contaminated with viruses cannot be ruled out.
According to the Australian study, the virus survived longer on smooth surfaces like glass, stainless steel and vinyl compared to pore-rich composite surfaces like cotton. An important finding is the shelf life of the virus in the glass. Because ATMs, self-service checkouts in supermarkets, and check-in machines at airports have surfaces that are frequently touched and may not be cleaned regularly. So the rule still applies: wash your hands often and clean surfaces.
