It’s hypothetically possible, but parcels pose a very small risk.
A US study found that the coronavirus can survive for up to 24 hours on cardboard (and paper is likely to be similar). So for the parcel to be contaminated, someone with COVID-19 would have had to touch or cough on your parcel within the past day.
The chances of this are low, but common sense advice would be to wash your hands with soap and water after opening the parcel, and then again after you’ve disposed of the packaging – especially if you or anyone else in your household is in one of the vulnerable groups.
The same study found that the virus can survive for up to three days on hard, shiny surfaces such as plastic and stainless steel – which is why door handles are particularly good vectors for the virus. So, if you receive anything packaged in plastic, such as takeaway deliveries, make sure to wash your hands after touching it, and especially before eating.
We don’t yet know how long the virus can survive on smartphone screens, but it’s likely to be up to three days. This means that you should ideally clean your phone with disinfectant wipes (Apple recommends 70 per cent isopropyl alcohol wipes), at least once a day.
