If you're healthy and have a quality ventilation system or a big kitchen, it may not be your biggest concern, though it will still impact the environment.
That's because the particles that carry the virus get diffused by circulating air, when people are gathered indoors in tight spaces without good ventilation that increases the likelihood of spread.
So opening the sacks in an open environment with your face away from them, rolling up the sacks after you've used them, potting on in an open air environment.
Normally you're in this outside well-ventilated space and on a windy day, it's probably not going to be an issue until you put the cuttings into the boot of your car to take to the tip.
