Household Transmission of SARS-CoV-2
A Systematic Review and Meta-analysis
Not sure if this has been posted in the thread yet or not but it is a meta-analysis of household transmission. It reviewed and collected data from 54 studies that looked at secondary attack rates in households, and estimated overall secondary infection rate to be 16.6%. The rates varied quite a bit as you may expect, as everything with this virus does. I think living quarters and culture play a large role in transmission. Also as noted in the study was transmission rates from children to adult and vice versa.
Interesting stuff, we assume everyone in the house is going to get it if someone is sick, and the secondary transmission rate is much much higher than similar viruses and illnesses. However 16.6% is probably lower than most people would guess.
