A Stanford professor shed light on an Australian study that suggests the coronavirus can survive on common surfaces, including layers of glass on smartphone screens for up to 28 days. Dean Winslow, an infectious disease physician and professor of medicine at Stanford University Medical Center, said the Australian study portrays what he calls a worst-case scenario.
“I think people shouldn’t worry too much about that,” Winslow told Mic. “I don’t think they need to worry about decontaminating their personal cell phone.” Winslow says the virus is spread more through internal interactions than through cell phones.
Such a situation could occur indoors, in the absence of UV light. when people don’t take sufficient precautions. This could occur in confined spaces, poor ventilation and prolonged exposure to respiratory particles.
“All the experiments were conducted in the dark, to cancel out any effects of UV light. The inoculated surfaces were incubated at 20 degrees Celsius, 30 degrees Celsius and 40 degrees Celsius and sampled at various points in time, “noted the scientists who conducted the study.
Winslow does not completely ignore the study, saying it is an important document. However, he claims that the situation in which the study was conducted was artificially created. According to Winslow, the researchers added a high concentration of viruses to each surface for the study “and it may be a little artificially high compared to what types of virus loads are actually found on inanimate objects.”
Winslow further explained that the researchers extrapolated the concentration from the amount of virus a swab would collect directly from an infected person’s nose or throat. A more real situation would be when a person with an unsuitable mask sneezes directly on the phone compared to concentrating directly from a tampon of the infected person.
Winslow says most of the super shedding events have taken place in crowded indoor environments and presses to avoid internal interactions as much as possible
Dean Winslow, a Stanford professor, says a recent Australian study that claims coronavirus spreading through cell phone surfaces portrays what he calls a worst-case scenario.
- A Stanford professor said people shouldn’t worry much about the spread of the coronavirus via cell phones.
- He noted that the study by Australian researchers used concentrated amounts of the virus in the absence of UV light.
- The professor noted that the risk of spreading the coronavirus through indoor events is much greater than spreading through cell phones.
