Researchers discover that Covid-19 can live on smartphone screens for up to 28 days

In March, when the covid-19 pandemic struck the globe, Apple finally told users that it was okay to use disinfectant wipes on the iPhone. At that time, the risk of infection was unclear and it was better to be safe than to regret. During that time, I learned that saliva droplets in the air pose the most obvious risk of transmitting the virus. When it comes to paying attention to the risk of surface infections, you may be a little careless.

Under laboratory conditions, the covid-19 was much more robust than previously believed, according to a new study from the CSIRO Scientific Institute in Australia. The team tested the sample on a non-porous surface (glass, polymer banknotes, stainless steel, vinyl, banknotes) in the dark at 68 degrees Fahrenheit and found that the infectious virus was recoverable for a whopping 28 days. .. This is 11 days longer than the flu virus survives under the same conditions. “These findings show that SARS-CoV-2 can remain infectious for a much longer period of time than is generally thought to be possible,” the researchers said.

However, your life is not designed around maintaining the ideal conditions for the coronavirus to thrive. Ultraviolet light is believed to be capable of killing viruses, and when Australian researchers raised the temperature in tests, their lifespan was shortened. At 86 degrees Fahrenheit, samples of stainless steel, polymer banknotes, and glass showed that live infectious viruses could be recovered for up to 7 days.

Non-porous materials such as cotton cloth were found to contain trace amounts of infectious virus at temperatures of 68 degrees Fahrenheit for up to 14 days. This is all fairly vague data to understand the personal risk of viral infection from the surface, but previous studies have shown that virus lifespan is close to 3 days for glass and 6 days for stainless steel. I did. In other words, you may need to pay more attention to the resilience of covid on the surface.

But don’t panic. Professor Ron Eccles, a former director of the Cold Center at Cardiff University, told the BBC that the new study could be alarming and criticized the study for not using fresh human mucus as a vehicle for the virus. He explained that the load of white blood cells in the mucus can be very hostile to the virus.

Since the beginning of the pandemic, little has changed with respect to recommended protocols for protecting yourself and others from the spread of the virus. Wear a mask, keep a good distance between yourself and others, wash your hands and avoid claustrophobia. This is not complicated, but it is more complicated than it should be due to the shift in risk research and the irregular policy shifts at the government level.

After picking up a box of cereals at a grocery store, you probably don’t need to act as if your fingertips are radioactive. Sure, wash your hands, but there are many environmental factors that work in your favor in that scenario. The device in your pocket often takes a sample of everything you inadvertently touch while on the go and should be wiped off every time you wash your hands.
