Experiments conducted by Australian scientists have revealed that the coronavirus that causes COVID-19 is more resistant than other viruses, including the flu 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 days longer than the flu virus can handle.
“These results demonstrate that SARS-CoV-2 can remain infectious for significantly longer periods of time than is generally considered possible. These findings could be used to improve risk mitigation procedures to prevent the spread of COVID-19, “the scientists said in their paper.
Now, before we throw the phone in the bleach, let’s go over the headlines. In the same article, Australian scientists also talked about the conditions that left the coronavirus for 28 days even though it is external to a host.
The 28-day life of the SARS-CoV-2 is in ideal conditions. This doesn’t mean that coronavirus stuck on a phone’s screen or bezel isn’t a real threat, because it’s a threat. But it just means you shouldn’t panic yet.
Scientists 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 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, “the scientists wrote.
Then they explained: “With initial viral loads substantially equivalent to the highest titers excreted by infectious patients, the viable virus was isolated for up to 28 days at 20 degrees Celsius from common surfaces such as glass, stainless steel and paper banknotes and In contrast, the infectious virus survived less than 24 hours at 40 degrees Celsius on some surfaces. “
So some key points:
Coronavirus can cling to phones and can spread if people touch phones touched by COVID-19 patients.
– Under ideal conditions, the coronavirus can survive up to 28 days on a phone’s glass screen.
– Under conditions where UV radiation is present, basically daylight, the coronavirus cannot last that long.
– In direct sunlight, the coronavirus will likely not be able to last more than a few hours on a phone screen. This is especially true because in direct sunlight, the phone screen also gets hot.
– With higher temperatures and most places in India are warmer than 20 degrees Celsius, most of the time the coronavirus cannot survive for 28 days.
– These real-world conditions, which include UV radiation, heat, airflow, etc., have previously led researchers to conclude that the main source of coronavirus infection is the droplets that COVID-19 infected people, symptomatic or asymptotic, they spread when they cough or talk. Surfaces like the phone screen are not the drivers of COVID-19 infections.
– Finally, in case you are worried about contracting the 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 about to eat out. And if you went out, after coming home, just like washing your hands, you can also clean your phone with an alcohol-based cleaner.
A new research report says the Coronavirus can survive on a phone screen for 28 days. While this sounds alarming, this part about coronavirus survival is a bit complicated too.
- Coronavirus can survive on a phone screen for 28 days.
- The COVID-19 virus is harder than the flu virus which can only survive for 17 days.
- Environmental factors also play a role in the life span of the coronavirus.
