Study reveals coronavirus can survive for almost a month on phones, banknotes

They found that when samples were tested in the dark at 68° Fahrenheit (20° Celsius) on non-porous surfaces (glass, polymer, stainless steel, vinyl, and paper), the virus was recoverable for 28 days.

A new study has revealed that SARS-COV-2 can remain active for up to 28 days on some surfaces.

While the study found exposure may not mean a person is completely immune from the virus, its suggestions also have "implications for the role of vaccination in response to COVID-19", according to researchers.

In comparison, the flu virus can survive in the same circumstances for 17 days. While the patient survived the second bout of the virus, his case raises questions about how long people are protected from COVID-19 after having survived an infection, USA Today reports.

The research team from Hokkaido University in Japan, have modelled available data from Japan, Spain, and Italy to show that susceptibility to Covid-19 is independent on age. He also added that this study not only has given the researchers the ability to accurately test for antibodies against the Coronavirus caused disease but also has "armed us with the knowledge that lasting immunity is a reality".

Although it is said that coronavirus is mostly transmitted when people cough, sneeze or talk but there is also evidence that it can also be spread by particles hanging in the air.

A case study published Monday in The Lancet showed the unnamed patient initially tested positive for COVID-19 in April after suffering from a cough and nausea.

"In my opinion infectious viruses will only persist for hours in mucus on surfaces rather than days".

ACDP director Professor Trevor Drew said many viruses remained viable on surfaces outside their host.

At around 20°C, the Covid-19 virus had remained infectious for almost a month on surfaces like banknotes and even the glass of a mobile phone screen.

"Our findings signal that a previous SARS-CoV-2 infection may not necessarily protect against future infection", he said.

COVID-19 can linger on surfaces twice longer than initially thought. Wash your hands regularly.

Eccles' words were backed up by a previous study conducted by US researchers in March, which showed that the virus was detected as viable in the air only for up to three hours. On 5 June tested positive for the second time and was found to by hypoxic (low blood oxygen) with shortness of breath.

The 25-year-old was infected with two distinct genetic strains of the new coronavirus within 48 days after testing negative in-between.

Nevada public health officials first reported the case of COVID-19 reinfection August 29.
