We always talk about washing our hands to prevent the spread of viruses, but we need to consider just how long viruses can last on different surfaces. The coronavirus can live for hours to days on surfaces like countertops and doorknobs. How long it survives depends on the material the surface is made from. On metal surfaces the virus can last five days unless it’s been cleaned and disinfected. One wood surfaces like table tops, the virus can last four days. On plastic surfaces such as packaging like milk containers and detergent bottles, subway and bus seats, backpacks, elevator buttons the virus can last two to three days. On stainless steel surfaces like refrigerators, pots and pans, sinks, some water bottles it can last two to three days. All of those packages you’ve been ordering, be aware that the virus can last up 24 hours on cardboard boxes.
