COVID-19 can live on cardboard for up to 24 hours, 3 days on plastic. I would suggest using gloves (if available) to open the package, have someone else remove contents, and then with gloves still on, dispose of the box in a container of some sort (garbage bag, etc). Wash hands after all contact with incoming material.
EDIT: Washing your hands well is probably sufficient; excuse my paranoia suggesting gloves, extraordinary times.
