A new study reveals that the coronavirus is extremely robust. The Sars-CoV-2 pathogen can stay on smooth surfaces for almost a month – this also includes everyday objects such as smartphones and banknotes. One factor has a decisive influence on the survival time of the virus. Under certain laboratory conditions, the coronavirus can survive for up to 28 days on smooth surfaces such as cell phone displays and ATMs. At least that’s what the Australian science authority Csiro writes in the “Virology Journal”. The experiment was carried out in the dark, as studies have shown that direct sunlight can kill the virus quickly. The German Federal Institute for Risk Assessment (BfR) states that it is not aware of any corona infections via surfaces such as card terminals and smartphones. “At 20 degrees Celsius, around room temperature, we found the virus to be extremely robust and survive for 28 days on smooth surfaces like glass on cell phone screens and plastic banknotes,” said Debbie Eagles, deputy director of the Australian Center for Disease Prevention. who carried out the research.

In previous studies, the coronavirus 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.

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 and surfaces and that infections occurred. However, according to the information, smear infections cannot be ruled out via surfaces that have recently been contaminated with viruses. 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 frequently and clean surfaces.
