Here, we report a systematic review of household transmission studies of and try to assess the secondary attack rate of household COVID-19 transmission. Studies containing data on household transmission of COVID-19 were retrieved from the electronic databases: PubMed, Embase, and a Chinese database, China National Knowledge Infrastructure (CNKI) on 1 July, 2020. Case reports with only one family involved were also excluded for analysis, because the household transmissions event collection was biased towards infection caused more serious illness. Household secondary attack rate (SAR) was calculated as the number of identified cases divided by the number of household contacts. Household SAR were greater than SAR by other contacts (OR=10.72, 95% CI: 5.70-20.17, p<0.001), suggesting much higher rates of intra-family transmission of COVID-19.	./cache/cord-308852-qdn04pun.txt	./txt/cord-308852-qdn04pun.txt
