Covid-19 virus can survive up to 28 days on common surfaces like currency notes, smartphone screen mirrors and stainless steel. Research from the Australian National Science Agency has revealed these shocking facts. It was previously believed that the virus lived on surfaces for a maximum of three days.
The study was conducted by a national science agency called the Australian Center for Disease Preparedness (ACDP). ACDP Deputy Director Debbie Eagles said the virus survives for 28 days on smooth surfaces such as glass, plastic currency notes, mobile phone screens. The study is published in the journal Virology.
Researchers last longer on smooth surfaces. The researchers found that the virus of Covid-19 can survive for long periods of time at low temperatures and without holes and smooth surfaces such as glass, stainless steel, plastic sheets, etc. It is able to last for a long time on complex surfaces such as perforations. Researchers also found that the virus is present longer on a plastic note than on a paper note.
In such a study, the
researchers observed a strong presence of the virus on different surfaces at room temperature ie 20 ° C. As the temperature increased during the experiment, their survival time decreased. Researchers also conducted this study in the dark so that the UV rays emanating from the sun do not reach the virus, as it was observed during research that sunlight affects the virus.
will be able to save 1 more lives –
researcher Larry Marshall says that after detecting the survival period of the virus on different surfaces, a better strategy can be made to reduce its spread. More number of lives will be saved.
2. The risk of increasing infection in winter, in
such a situation, scientists worry that the presence of virus on the surfaces in winter will be longer, which will increase the infection.
Virus lasts longer in cold temperatures
20 degrees: At this normal temperature, the virus survived 28 days on glass, steel, paper and polymer banknotes, while 14 days on Corton.
30 degrees: The virus could stay on the paper currency for 21 days as soon as the temperature rose ten degrees. It survived seven days on glass, steel and polymer banknotes, and three days on Corton.
40 degrees: At this temperature, the virus on the corona virus corten survived for less than 16 hours. It could last 24 hours on glass, steel and paper. A polymer called vinyl was present for 48 hours.
What were the first claims – The
virus can remain on plastic and stainless steel for 72 hours.
– Presence on cardboard for less than 24 hours and copper for less than four hours.
-The American Health Agency had reported the presence of RNA of the virus for 17 days.
