The coronavirus can live much longer than the flu virus on smartphone screens



While it demonstrates the importance of cleaning and disinfecting phones and other surfaces, the study does come with some big caveats. It was conducted at a constant 68 degrees F in dark conditions to negate the effects of UV light, away from real-world conditions. The experiment also did not use fresh mucus – normally present with viruses on surfaces – which contain white blood cells and antibodies. “In my opinion infectious viruses only persist for hours in mucus on surfaces rather than days,”

; Cardiff University Professor Ron Eccles told BBC.

Recently, experts have also downplayed the risk of coronavirus transmission from surfaces. According to the Center for Disease Control (CDC), “spread from touching surfaces is not considered a common way COVID-19 spreads.” Rather, the most common vectors are respiratory droplets produced by coughing or sneezing. New guidelines also suggest it can also be airborne in “poorly ventilated, enclosed spaces that often involve activities that cause heavier breathing, such as singing or exercise.”
