There is ongoing research about how long the virus that causes COVID-19 can live on surfaces such as cardboard, plastic, stainless steel, and copper. There is still no indication that COVID-19 illness can be contracted from mail or packages. Spread is still considered to be most likely person to person. However, to provide an extra measure of sanitization, you can wipe off packages with disinfectants before you bring them in your house. You should still wash your hands after opening/handling packages. It is also important to continue to clean high touch surfaces such as counters, light switches, and door knobs regularly.
