Can I ask if you experienced covid in your family - what was the experience like in your family?
Did everyone in the family contract the virus or was it just some members of the family? If it was limited to one a member or two of the family and others didn't contract the virus - how are the hygiene measures? Was the hygiene measures stringent?
The reason I ask is my family believe if the virus gets into the household it will travel around to all. I believe it doesn't have to go to everyone in the house if everyone makes an effort with the appropriate hygiene measures of coughing and sneezing into elbow, appropriate hand hygiene, isolation in a room if feeling unwell.
