Here’s a guide to how long coronaviruses — the family of viruses that includes the one that causes COVID-19 — can live on some of the surfaces you probably touch every day.
Different Kinds of Surfaces
Metal
Examples: doorknobs, jewelry, silverware
5 days
Wood
Examples: furniture, decking
4 days
Plastics
Examples: milk containers and detergent bottles, subway and bus seats, backpacks, elevator buttons
2 to 3 days
Stainless steel
Examples: refrigerators, pots and pans, sinks, some water bottles
2 to 3 days
Cardboard
