While it shows the importance of cleaning and disinfecting phones and other surfaces, the study comes with some big caveats. To deny the effects of UV light away from real world conditions it was done at a constant temperature of 68 degrees F in dark conditions. The experiment did not use fresh mucosa – usually present with a virus on the surface – containing white blood cells and antibodies. “I think the infectious virus will stay on the surface for hours of saliva rather than just days,” said Ron Eckhalls, a professor at Cardiff University. BBC.
Recently, experts have also reduced the risk of coronavirus transmission from surfaces. According to the Centers for Disease Control (CDC), “Spreading from a touch surface is not considered a common way to spread COVID-19.” , Larynx, the most common vector are respiratory drops produced by coughing or sneezing. The new guidelines also suggest that it may also be transmitted by airborne transmission, such as “airtight and closed spaces that often include activities that involve heavy breathing, such as singing or exercise.”
