In this cluster of COVID-19 cases, little to no transmission occurred from asymptomatic case-patients [0 cas en fait]. Presymptomatic #transmission was more frequent [75%] than symptomatic transmission. The serial interval was short [incubation médiane : 4,3 jours] ; very short intervals occurred.

In conclusion, our study suggests that asymptomatic cases are unlikely to contribute substantially to the spread of #SARS-CoV-2. #COVID-19 cases should be detected and managed early to quarantine close contacts immediately and prevent presymptomatic #transmissions.
