I don't understand how you would catch the virus in that circumstance, can you please explain it to me.
Huyton Red just named one or two of many ways heimdall. Basically saying even if you do everything right can still catch it.
Let me explain how life as been for me two weeks before lockdown. First of all I'm in the 20% bracket whereas I'm more vunrable than others to possible catching the virus due to my health issues, not going into my health side as isn't warranted.
To some people (( definitely me )) I'm more paranoid than most so extra careful, many will say over extreme but can't be helped. It's my choice and if it means there's 0.1 less chance of me getting the virus then it's worth.
My two children were doing my shopping until last week whereas I've now ventured out. However, when they bring my shopping they don't come into the house as you can even walk in after picking something off your shoes, highly unlikely but still possible. They leave shopping at the door, I use gloves in case any germs on bags or even my shopping goods till I wash/clean as many items as possible in a bacteria & virus protector.
Food doesn't stock itself, many staff don't use gloves/masks so can inadvertently pass virus un be knowing that they may have the virus also. Hell, I even spray my soles when I come. I also put my cloths straight into the wash. Yes I'm going overboard as stated in my paranoia.
Literally anyone can just brush again and accidentally rub something on your clothing, you have a itch and scratch accordingly. Thus leaving it on your hands and then you may just rub your/nose/mouth/eyes and outside chance you could pick something up.
Apparantly one of the worse places for picking virus up is shopping and petrol stations. So even if you don't go still possible a outsider can bring it to your doorstep. It's that bad for me I don't even open mail up without gloves then still wash my hands.
Like I've said, if there's 0.1 chance less of me picking virus up through my paranoia them I've atleast tried my best.
Hope this helps.m
