Tour group transmission may have occurred in the following sceParis-Shanghai, all of the confirmed and suspected cases had seats within two rows ( Figure 3 ). We reported three clusters of COVID-19 confirmed cases in three tour groups travelling in European countries and one cluster of suspected cases on one flight in late January 2020. In group A, the cluster was initiated by a familial transmission, followed by spread of disease to 13 out of 34 members in the 12-day tour. In conclusion, we reported a cluster of 13 COVID-19 cases, which was initiated by within-family transmission followed by propagative transmission into tour groups travelling in European countries. The study findings show that clustered cases in tour groups may be more propagative than simple familial transmission.
