In this news, we discuss the Research shows coronavirus survives on phone screen for 28 days but don’t panic yet.
Experiments by Australian scientists have revealed that the coronavirus responsible for COVID-19 is more resistant than some other viruses, including the influenza virus. Scientists have found that the coronavirus can survive on common surfaces, including layers of glass on smartphone screens, for up to 28 days. That’s 11 more days than the flu virus can handle.
“These results demonstrate that SARS-CoV-2 can remain infectious for much longer periods of time than is generally considered possible. These findings could be used to inform improved risk mitigation procedures to prevent the fomite spread of COVID-19, ”the scientists said in their article.
Now, before you throw your phone in the bleach, let’s get past the headlines. In the same article, Australian scientists also discussed conditions that allow the coronavirus to last for 28 days, even if it is outside of a host.
The 28-day life of SARS-CoV-2 unfolds under ideal conditions. This doesn’t mean that the coronavirus stuck to the screen or frame of a phone isn’t a real threat, because it is a threat. But that only means that you shouldn’t panic just yet.
Scientists have found that the coronavirus survives 28 days in a laboratory, with controlled conditions, a dark environment and a temperature set at 20 degrees.
“All the experiments were conducted in the dark, to negate any effect of UV light. The inoculated surfaces were incubated at 20 degrees Celsius, 30 degrees Celsius and 40 degrees Celsius and sampled at different times, ”the scientists wrote.
Then they explained, “With initial viral loads broadly equivalent to the highest titers excreted by infectious patients, viable virus was isolated for up to 28 days at 20 degrees Celsius from common surfaces such as glass, stainless steel and paper and polymer banknotes. Conversely, the infectious virus survived less than 24 hours at 40 degrees Celsius on some surfaces. “
So, a few key points to remember:
– The coronavirus can latch onto phones and spread if people touch phones affected by COVID-19 patients.
– Under ideal conditions, the coronavirus can survive for up to 28 days on the glass screen of a phone.
– Under conditions where there is mostly daylight UV radiation, the coronavirus cannot last that long.
– In direct sunlight, the coronavirus will probably not be able to last more than a few hours on a phone screen. This is especially true since in direct sunlight, the phone screen also heats up.
– At higher temperatures and most places in India are hotter than 20 degrees Celsius most of the time, the coronavirus cannot survive for 28 days.
– These real-world conditions, which include UV rays, heat, airflow, etc., previously led researchers to conclude that the main source of coronavirus infection is the droplets that people infected with COVID -19, symptomatic or asymptotic, spread when they cough or speak. Surfaces like the phone screen are not the engines of COVID-19 infections.
– Finally, if you are worried about catching coronavirus by touching your phone, be careful not to place the phone in public areas, for example on a restaurant table in case you are going to eat out. And if you are out, after you get home, just like you wash your hands, you can also wipe the phone with an alcohol-based cleaner.
A new research report says the coronavirus can survive on a phone screen for 28 days. While it sounds alarming, this bit about coronavirus survival is also a bit complicated.
- The coronavirus can survive on a phone screen for 28 days.
- The COVID-19 virus is more resistant than the influenza virus which can only survive for 17 days.
- Environmental factors also play a role in the lifespan of the coronavirus.
