Yes you can. If somebody who is infected with Covid-19 has touched, breathed, or coughed onto the surface before you have touched it, there is a chance the virus will be present. It can also be present in fecal particles from infected people in toilets. If you touch these areas, the virus can be passed to the part of your body that has made contact, and can then cause an infection if the contaminated part of the body then touches the eyes, nose or mouth. The virus can survive for differing times on various surface materials: up to 24hrs for fabric, paper and cardboard; up to 3 days (72hrs) on plastic, glass and stainless steel; and 4hrs on coins containing copper. Communal surfaces should be cleaned as often as is viable. It is important to wash or disinfect your hands after touching these surfaces, you can wear disposable gloves if you prefer, and avoid touching your mouth nose or eyes as much as possible.
