The coronavirus that causes COVID-19 can remain in pieces such as banknotes and phones for up to 28 days in cold and dark situations, according to a study conducted by Australia’s national clinical firm. -2 in the dark to 3 temperatures, apparently survival rates were falling as situations became warmer, the firm said on Monday.
Scientists found that at 68 degrees Fahrenheit, SARS-CoV-2 is “extremely resistant” on sleek surfaces, such as mobile phones and other touch screens, and survives for 28 days in glass, metal banknotes and plastic.
At 86 degrees Fahrenheit, the survival rate dropped to seven days and was reduced to 24 hours to 104 degrees Fahrenheit.
The d virus for shorter periods on porous surfaces such as cotton, up to 14 days at the lowest temperatures and less than 16 hours at the highest, according to the researchers. This was “significantly longer” than previous studies that showed that the disease can only up to 4 days on non-porous surfaces, according to the paper published in Virology Journal.
Separate studies published this week through the Kyoto Prefectural Medical University in Japan found that the new coronavirus is exceptionally durable on human skin, surviving up to 11 hours. This compares with approximately two hours of expected longevity for influenza A (influenza) virus on the skin. Japanese scholars said that this durability “could increase the threat of tactile transmission . . . thus accelerating the pandemic. “
The authors stated in their study, in the journal Clinical Infectious Diseases, that the findings highlight the importance of hand washing and disinfection.
Trevor Drew, director of the Australian Center for Disease Preparedness, said his examination was about drying samples of the virus in other fabrics before testing them, an “extremely sensitive” approach that discovered lines of live viruses capable of infecting mobile crops.
“That doesn’t mean that this amount of virus can infect someone,” he told the state broadcaster ABC.
He added that if someone “is reckless with those fabrics and touches them and then ingests their hands or touches their eyes or nose, it is quite possible that you will inflate more than two weeks after they become contaminated. “
Drew said there were several warnings, adding that the test was conducted with constant degrees of virus that probably represented the spike of a typical infection and that there was a lack of exposure to ultraviolet light, which can temporarily degrade the virus.
Humidity remained solid at 50 percent, according to the study, as moisture increases were also found to be negative for the virus.
According to CSIRO, the virus appears to spread basically through the air, but additional studies are needed to provide additional data on the transmission of the virus across surfaces.
“While the exact role of surface transmission, the degree of surface contact, and the amount of virus required for infection remain not d, it is imperative to know how long this virus remains viable on surfaces to expand mitigation methods of threats in the best touch areas, “said CSIRO’s Debbie Eagles.
The main message refers to “other infectious people being more contagious than surfaces,” Drew told ABC.
“However, it can help that even when we get rid of infectious people, we have those eruptions back infrequently, even in a country that is considered free,” he said.
