If you touch the credit card machine in the supermarket or the gym’s exercise machine you may be up for an infection.<\/p>\n
At the peak of the coronavirus, you may have realized that you risked getting infected by touching these kinds of surfaces. But it is only now that research has really begun to look at viruses on surfaces that can act as sources of infection in public spaces. Scientists now know that they can<\/em> lead to infection through indirect contact, which is contamination via surfaces.<\/p>\n Johannes Roth Madsen and Jacob Pohl Stangerup Nielsen study seventh and eighth semester medicine, respectively, at the Faculty of Health and Medicine at the University of Copenhagen.<\/p>\n For one week last winter in the period 2-8 February 2022, they looked for virus residues from Sars-Cov-2 (coronavirus) on a total of 357 surfaces in Copenhagen.<\/p>\n By doing so, the two medical students helped launch a new project with six other researchers to find out how people infect each other indirectly.<\/p>\n \u00bbThe study has proven that coronavirus can sit as particles on surfaces that we touch in the course of our daily lives,\u00ab says Johannes Madsen. The two medical students are surprised about this result, as no one needs to touch the travel card machines to check in. They don’t yet have a good explanation.<\/p>\n No previous Danish study has been done that shows how humans can be indirectly infected with Sars-Cov-2. There are, on the other hand, Danish studies on how we can be directly infected via, say handshakes, or when the infection floats through the air as droplets via sneezes from person to person.<\/p>\nFound evidence of coronavirus on surfaces<\/h3>\n

\nThe study found that 42 per cent of all of the examined credit card machines in supermarkets and in other places had RNA from Sars-Cov-2 on their surfaces. The Rejsekort travel card machines in public transport had remnants of it in 40 percent of cases.<\/p>\nOffers perspective on influenza virus also<\/h3>\n
