The secondary transmission rate in the RTLS model was 8.1%, while that in the conventional model was 5.3%. The multivariable logistic regression model revealed that the RTLS was more capable of detecting secondary transmission than the conventional method (adjusted odds ratio 6.15, 95% CI 1.92-28.69; P=.007). Conclusions: This study showed that the RTLS is beneficial when used as an adjunctive approach to the conventional method for contact tracing associated with secondary transmission. However, the RTLS cannot completely replace traditional contact tracing. %M 36197844 %R 10.2196/41395 %U //www.mybigtv.com/2022/10/e41395 %U https://doi.org/10.2196/41395 %U http://www.ncbi.nlm.nih.gov/pubmed/36197844
