Washington, Pretr. At the beginning of the outbreak of the corona epidemic, many other measures were adopted from the lockdown to prevent the spread of infection. There was a belief that the corona virus is also spread through banknotes. Therefore, the behavior of cash in mutual transactions decreased and many institutions also banned cash transactions. Even people started sanitizing the note. But now a study has come to the fore that SARS-CoV-2 (coronavirus in common language) on banknotes ends immediately. There is more danger than that from debit, credit, on which the virus can remain active for a long time. This research, published in the journal PLOS One, states that the promotion of credit, debit card transactions instead of cash is not appropriate to prevent infection of Kovid-19.

Researchers have found that the virus is more stable on plastic money and lives up to 48 hours after it has been deposited on it. However, the virus was not found to be active on the cash or card samples collected for the study.

At the beginning of the corona epidemic, there was a big outcry about cash

The study’s author, Professor Richard Robison from Brigham Young University in the US, said at the beginning of the pandemic there was a lot of talk about stopping the use of cash in business. Many establishments have adopted this and declared that they will not deal with cash but debit, credit cards. So I wondered whether the data also supports this notion? But it was nothing like that. Then we decided to investigate whether these things were logical or not. There was no such thing in this also.

To investigate this, researchers have implanted SARS-CoV-2 on dollar notes, coins and credit cards. Thereafter, these cash notes, coins and cards were checked at various intervals- 30 minutes, four hours, 24 hours and 48 hours.

Even after 48 hours live virus was present on the money card

Researchers found that it was difficult to find or detect SARS-CoV-2 after just 30 minutes on the dollar note. In such a short time, the virus was reduced by 99.9993 percent. After this, the researchers checked again after 24 hours and 48 hours and found that there was no live virus on the banknote. In contrast, after 30 minutes, the virus on the money card was reduced by only 90 percent. In four and 24 hours, the rate of its reduction increased to 99.6 percent. But even after 48 hours live virus was present on the money card.

The case of coins remained the same as that of plastic cards. Despite the rapid reduction in the virus in the initial period, the test came back positive after 24 and 48 hours.

Researchers were surprised to see the volatility of the virus on paper banknotes. The special thing is that the American banknote consists of 75 percent cotton and 25 percent linen. After 24 hours of putting about 10 lakh live viruses on the banknote, there was no live virus left on it.

research done like this

The team of researchers collected US$1 in cash bills and coins from restaurants and around BYU’s campus to trace the presence of the virus. An hour after collecting the cash, the researchers wiped the notes and coins with sterile cotton. Simultaneously they wiped the cards and they did not find RNA of SARS-CoV-2 on the banknotes and coins, while money was found in small quantities on the cards.

Robison said that this epidemic also became notorious for the fact that people made decisions without any data. It happened that some people said something and others spread it without any logical basis and started implementing it. In this way many wrong decisions were taken.
