Shocking new facts that have come to light about how durable it is coronavirus and the days when it can survive on the various items we use on a daily basis.
SARS-CoV-2, the virus that causes COVID-19, can survive on banknotes, glass, or stainless steel for up to 28 days.Much more than the flu virus, Australian scientists announced on Monday (10/12) a figure that underscores the need for cleaning and hand washing to combat the pandemic.
At 20 ° C, SARS-CoV-2 remains contagious for 28 days on smooth surfaces, according to researchers from the Australian National Scientific Organization (CSIRO) (Commonwealth Scientific and Industrial Research Organization)such as laminated banknotes or glass of the kind used to make mobile phone screens. The results of their study are published in the Virology Journal.
By comparison, influenza A virus has been found to survive on such surfaces for 17 days.
CSIRO’s research, according to the Athens News Agency, included drying the virus, turning it into artificial mucus, placing it on surfaces in concentrations similar to samples from COVID-19 patients, and then extracting it after about a month.
Experiments performed in controlled laboratory settings at 20, 30 and 40 ° C showed that the survival time of the virus on surfaces decreased as the temperature increased.
«Checking how long the virus actually remains viable on surfaces allows us to anticipate and mitigate its spread and do a better job of protecting our citizens.CSIRO CEO Larry Marshall said in a press release.
Proteins and fats contained in body fluids can also greatly increase the survival time of the virus.
“This research may also help explain the apparent resilience and spread of SARS-CoV-2 “In cold environments with high levels of lipids or protein, such as meat processing plants, and how can we best deal with this risk,” said Trevor Drew, director of the Centers for Disease Control at CSIRO.
Australia performs significantly better than most other wealthy countries in fighting the coronavirus pandemic. To date, it has confirmed approximately 27,000 SARS-CoV-2 infections and recorded 898 deaths from COVID-19 out of a total population of 25 million.
The epicenter of the so-called second wave of the pandemic in Australia, the state of Victoria, registered 15 new cases of contagion today, a figure well above the 5 or less that the authorities said was the level they want to reach before making even more flexible. plus restrictive measures in Melbourne, the state capital.
New South Wales, the most populous state in the country, has registered six new cases of infection today, five of which are returned travelers and quarantined.
