Studies find COVID-19 coronavirus can survive 28 days on some surfaces, 11 hours on skin

The coronavirus that causes COVID-19 can survive on items such as banknotes and phones for up to 28 days in cool, dark conditions, according to a study by Australia’s national science agency. Researchers at CSIRO’s disease preparedness centre tested the longevity of SARS-CoV-2 in the dark at three temperatures, showing survival rates decreased as conditions became hotter, the agency said Monday.
The scientists found that at 68 degrees Fahrenheit, SARS-CoV-2 was “extremely robust” on smooth surfaces — like cell phone and other touch screens — surviving for 28 days on glass, steel and plastic banknotes.
At 86 degrees Fahrenheit, the survival rate dropped to seven days and plunged to just 24 hours at 104 degrees Fahrenheit.
The virus survived for shorter periods on porous surfaces such as cotton — up to 14 days at the lowest temperatures and less than 16
