The scientific journal iScience has released the results of a study carried out by specialists in virology at the Ruhr-Universität Bochum, Germany, in collaboration with the European Central Bank, which sought to determine how long the covid-19 virus remains in banknotes and coins. The research also sought to find out what is the risk of contracting the disease when handling these objects.
To analyze the stability of the virus in coins and banknotes used in the European Union, experts exposed money of different denominations to the pathogen that causes covid-19 for several days.
In 10-euro notes, the virus disappeared after serving three days. In ten cents, the virus disappeared after six days, and in one euro, it only lasted an hour.
Daniel Todt, co-author of the study, explains that viruses are less stable on copper, a material that some coins are made from, such as nickel. For this reason, the pathogen quickly disappeared.
The study found that the risk of contracting the disease from handling banknotes and coins is low, according to iScience magazine.
Despite the low risk, authorities around the world still recommend disinfecting cash. The Interactive Museum of Economics in Mexico even published instructions on how to do it.
How to disinfect banknotes and coins?
So much for disinfecting coins and notes, not only against the coronavirus, but also against bacteria and dirt, the Mexican museum recommends the use of gloves and a mixture of water and chlorine.
In the case of banknotes, it is advisable to place the mixture of water and chlorine in a spray bottle and then spray the money, taking care not to get too wet. Later, they recommend using a clean, dry cloth carefully to avoid bending or breaking. Coins can be soaked in the bleach-water mixture for one minute before drying with a clean cloth.
Fadela Chaib, a spokesperson for the World Health Organization (WHO), highlighted in 2020 that there is no evidence that the virus is transmitted through money, although that organization has always recommended that they wash their hands afterwards. handle banknotes or coins and avoid touching your face.
