Should I avoid touching surfaces when shopping during the COVID-19 pandemic?
See full answerResearch suggests that COVID-19 is more commonly spread from respiratory droplets passed from people in close contact than from touching surfaces. It is possible but probably less common that those droplets land on surfaces, and then a person gets infected by touching their own mouth, nose, or eyes, after touching the surface (source). Washing your hands with soap and water (or using alcohol-based hand sanitizer) regularly and avoiding touching your face will help with this concern. Another important way to avoid getting the virus while shopping is to wear a mask and stay at least 6 feet away from others.
