Corona virus “remains active on banknotes and phone screens for 28...

Researchers have confirmed that the Corona virus can remain in an active state for 28 days on some surfaces, such as banknotes, cell phone screens, and non-porous “stainles” metals.

A study conducted by a team of researchers at the National Institute of Science in Australia confirmed that the SARS-Cove-2 virus can survive for longer periods than it was imagined on some surfaces, and the virus is transmitted mostly due to coughing or sneezing and talking.

However, some experts assert that there is a possibility of transmission of the infection through virus particles spread in the air or settled on some metal, plastic or paper surfaces.

Previous studies had suggested that the virus would remain active on bank notes for two days and on glass, plastic and metal surfaces for six days. But the recent study found that the virus was highly active on these surfaces for a period of up to 28 days, especially soft-touch surfaces such as the glass used to make mobile phone screens, as well as soft-touch plastic containers and paper currencies.

The researchers pointed out that these results were reached after a period of intensive research for the activity of the virus at a temperature of 20 degrees Celsius, which is almost the usual room temperature.

Compared with the usual influenza virus, Corona can remain active for 17 days in the same life conditions.

Research was conducted in dark conditions as UV rays were known to help kill the virus.

Larry Marshall, director of the institute, said, “Discovering how long the virus remains in the phase of activity on different surfaces helps us predict and predict its activity and behavior more accurately and provide more effective solutions to help people avoid infection.”

The study, published by the “Virology Journal” specialized in virology, found that the virus remains active for a shorter period at high temperatures. The possibility of transmission from contact with some surfaces is limited to a period of 24 hours only at a temperature of 24 degrees Celsius.

The virus activity persisted longer over smoother, non-porous surfaces than others. The study also found that clothes do not continue to have active and contagious corona viruses on them for more than 14 days.

Corona can be transmitted through the air. Studies have found that the virus can remain active in air particles for more than three hours, while the possibility of transmission via banknotes and mobile phone screens was less certain.

Previous studies also looked at how long the virus lived on smooth metal surfaces, and their results varied greatly. Some have found that the virus remains active for three days at most, while other studies have confirmed that it remains active for up to 14 days at room temperature.

But the last study looked at the duration of virus activity on glass, metal and paper surfaces and found that active viruses can be tracked for up to 28 days at room temperature, which is significantly more than previous studies.

The study was conducted in environments prepared for the survival of viruses, including darkness, stable temperatures and high humidity, which are the conditions that are not available for the virus naturally and continuously.

Nevertheless, the results add more importance to washing hands regularly and avoiding contact with the face to reduce the risk of infection.

The researchers found that the ability of the SARS-Cove-2 virus to remain in an active state on smooth metal surfaces at low temperatures could explain the outbreak of infection in meat processing plants and cold food stores that had been shown to infect thousands of workers in them around the world in the past.

The latest study supported the results of previous studies of the virus remaining active in some fresh and frozen foods.

The World Health Organization says that “there are currently no confirmed cases of the virus due to its transmission through fresh or packaged foods,” but the organization provides some advice and instructions to avoid the risks of transmission across different surfaces.
