Coronavirus that causes COVID-19 According to a study by Australia’s National Science Agency, things like notes and phones can last up to 28 days in cold and dark conditions. Researchers at the CSIRO Disease Preparedness Center tested the lifespan of SARS-CV-2 in the dark at three temperatures, which showed a decrease in survival rate as the situation got warmer.
Scientists have discovered that at 68 degrees Fahrenheit, the SARS-Cavi-2 was “extremely strong” on smooth surfaces – such as cell phones and other touch screens – that live up to 28 days on glass, steel and plastic banknotes.
At 86 degrees Fahrenheit, the survival rate went down in seven days and sank in just 24 hours at 104 degrees Fahrenheit.
The virus survived for a short period of time on porous surfaces such as cotton – at a minimum temperature of 14 days and a maximum of less than 16 hours, the researchers said. This was “significantly longer” than previous studies, according to a paper published in the peer-reviewed Virology Journal, which found that the disease can live up to four days on a non-porous surface.
A separate piece of research published this week by Kyoto Prefectural University of Medicine in Japan has found that the new coronavirus is unusually durable on human skin, even if it lives up to 11 hours. That compares to the expected lifespan of about two hours for the influenza A (flu) virus on the skin. Japanese researchers said the sustainability “could increase the risk of contact transmission … thus accelerating the epidemic.”
The authors said in their study, published in the journal Clinical infectious diseases, The findings show the importance of hand washing and disinfection.
Trevor Drew, director of the Australian Australian Center for Disease Preparation, said his study involved drying virus samples on a variety of materials, using a “highly sensitive” method that found traces of live viruses that could infect cell culture.
“This does not mean that the virus will be able to infect anyone,” he told public broadcaster ABC.
He added that if a person “is careless with this material and touches it and then licks your hand or touches your eyes or your nose, you can be infected from above for up to two weeks after they become infected.”
Complex for “risk reduction”
Drew said the study was conducted with fixed levels of the virus, possibly representing the peak of a common infection, and the absence of exposure to ultraviolet light, which can quickly degrade the virus.
The study said that the humidity was kept stable at 50 percent, as the humidity was also found to be harmful to the virus.
According to CSIRO, this The virus is mainly spread in the air But more research was needed to give a better understanding of the transmission of the virus through surfaces.
“While the exact role of surface transmission, the degree of surface contact and the amount of virus required for infection remains to be determined, it is important to develop a risk reduction strategy in high-contact areas to determine how long the virus can survive on the surface,” said Debbie Eagles of CSIRO.
The key message remains that “infected people are more contagious than surface,” Drew told ABC.
“But nonetheless, it can help explain why, even when we’ve gotten rid of infected people, we sometimes take this breakout, sometimes even in a country where it’s considered free.”
