A mean of 0.7 contacts per case were reached by telephone by public health authorities and only 0.5 per case were monitored. In 9 locations, the median time from specimen collection to contact notification was 6 days or less. In 6 of 8 locations with population comparison data, positive test prevalence was higher among named contacts than among the general population. The authors suggest these findings indicate that despite being a high-yield activity for case finding, contact tracing had a suboptimal impact on SARS-CoV-2 transmission.\u00a0<\/span><\/li>\n<\/ul>\n<p><i><span style=\"font-weight: 400\">Lash et al.\u00a0(June 2021).
