3 days ago I took delivery of a parcel. Postman was wearing a mask and handed me the parcel. We talked for maybe 30 seconds and we were about a meter away from each other.
He lives next door to my mum who tells me that his wife had called her tonight to say she wouldn't be able to call like normal because her husband has tested positive.
How much do I need to worry about my exposure to the virus? I was shielding last time and about to go back into shielding so I'm nervous.
