According to new Australian research, the coronavirus can survive for up to 28 days on smooth surfaces such as cell phone displays or ATMs – and thus longer than previously assumed. This emerges from a study by the Australian science authority Csiro, which has just been published in the “Virology Journal”.
“At 20 degrees Celsius, around room temperature, we found that the virus was extremely robust and survived for 28 days on smooth surfaces such as glass on cell phone screens and plastic banknotes,” said Debbie Eagles, deputy director of the Center for Disease Prevention which the research was carried out.
The experiment was done in the dark – research has already shown that sunlight can kill the virus quickly, it 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 resilient the corona virus is.
Cleans surfaces regularly
According to the Federal Institute for Risk Assessment (BfR), however, there have so far been no cases in which it has been proven that the coronavirus was transmitted to people through contact with contaminated objects or through contaminated surfaces and that this led to infections. However, according to the information, smear infections via surfaces that were 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 composite, pore-rich surfaces like cotton. An important finding is the life span of the virus on glass. Because ATMs, self-service checkouts in supermarkets and check-in machines at airports have surfaces that are frequently touched and possibly not cleaned regularly. Therefore, the rule continues to apply: Wash your hands and clean surfaces frequently.
