Research from the Australian National Institute of Sciences suggests that the new coronavirus may last much longer.
According to the BBC, the study was conducted in a controlled laboratory setting, in the dark. Researchers have already shown that ultraviolet rays can kill the virus.
However, in reality, some experts have been skeptical about the risk of spreading the infection from the surface. In most cases, the coronavirus is spread by sneezing, coughing, and talking.
But there is also evidence that the coronavirus can be transmitted through airborne particles. According to the US Centers for Disease Control, some people can become infected with Covid-19 by touching the metal or plastic surface that contains the virus. However, the incidence of such infections is considered to be very low.
Previous laboratory tests have shown that SARS-Cove-2 can survive two to three days on banknotes and glass and up to six days on plastic and stainless steel. However, the results of different studies are different.
But research by the Australian company CSIRO suggests that the virus is “extremely powerful.”
The virus has been found to survive up to 28 days on smooth surfaces such as glass and plastic and paper bills used on mobile phone screens at temperatures of 20 degrees Celsius in the dark.
In the same environment, the common flu virus can survive for up to 18 days.
The study, published in the journal Virology, found that SARS-COV-2 can survive warmer than cold temperatures. At a temperature of 40 degrees Celsius, its ability to infect some surfaces ceases within 24 hours.
It survives longer on smooth, porous surfaces than polyethylene materials like fabrics. It was found that no infection was spread through clothing in 14 days.
Criticizing the study, Ron Eckels, a professor at the Common Cold Center at Cardiff University, said the idea that the virus could live up to 28 days would spread “undue fear among the public.”
