> Something between “almost nothing” and “nobody leaving the house” would be nice. Based on who tested postive (and indeed negative) when, it appears our 8 year-old gave it to my OH, but not to his 12 year-old brother (with whom he shares a bedroom). When my OH had it, she didn't give it to me, either, and I was testing very frequently back then due to work & travel requirements. There is a hypothesis that the risk of catching Covid from someone may be related to the relative blood types. Based on the veeery small sample size of our immediate family it's definitely not the case that Covid always spreads quickly round a family group, despite us not having changed anything about our family routine when somone in the house was positive. We didn't send anyone to a separate bedroom, no-one wore a mask at home, and we all sat at the meal table together just as normal. FWIW My 12 year-old and I had Covid approximately two months later, when he caught it in his school and brought it home.
