I'm cleaning or binning everything that comes through the door.
I'm opening my post wearing gloves then putting it straight in the outdoors recycling if I can so it doesn't even come in the house.
Today I had a delivery of A4 coloured paper, tissues (toilet paper substitute, can't find any), water, biscuits, 4 x lion bars in a packet and 8 x kit kats in a packet. (This was from 3 days ago when I couldn't find any proper food to order online. Viking stationary was doing chocolate bars & drinks so I ordered some to cheer us all up! The drinks didn't turn up disappointingly but kids delighted with the chocolate.)
I opened the boxes wearing gloves and put them straight in the recycling. I left everything in the porch for a while. Then I got the chocolate bars, wearing gloves. opened the packets and tipped the insides out without touching them. I threw the outer packet in the outside bin.
I opened the biscuit packed and poured all the biscuits into a tub without touching them. Threw all the wrappers away and washed my hands again.
The tissues, water and craft paper are still out there. The water is wrapped in plastic so I'll do similar with that. Not sure what I'm going to do about the tissues. I can't very well wash the boxes. I might take them out too.
All this might sound extreme - I'm not usually paranoid about cleanliness at all - my house is a tip!
But since I read how long coronavirus can survive on surfaces, I know it can come in the house on parcels and the people delivering are out and about so at risk.
This might be total overkill, but I don't think so. Also, I'm conscious there could be a worse virus in future if we don't learn from this and carry on cutting down the rainforests and jungles of our planet and seeing what comes out of them - I'm just thankful it's not the children we're watching dying in Italy and China etc and knowing it's us next. So, I think even if I am overreacting, it's a useful exercise to see how I could protect my family from something that contagious in future.
Not sure if I've got it right yet. I suppose time will tell...
