Based on the transmission-dynamic parameters estimated here, we simulated observations from our estimated model and assumed that only one home visit was carried out. To eliminate the effect due to the time of implementing the interventions, we only considered households with initial home visit within the same day as the symptoms onset of the index case. We computed the simulated difference of RT-PCR-positive between HH group and control group. We considered seven scenarios in which the home visit was carried out, respectively, at day 0, day 1, day 2, day 3, day 4, day 5, and day 6 since the symptoms onset of the index cases.
