For the central air conditioner was always running at home, the infection risk of COVID-19 would have increased when Patient 1 gathered with other family members during his incubation period, which indicated that close contact, especially in a small enclosed space, might be the cause of familial transmission. Family members, especially of whom the confirmed cases contacted with since one incubation period before onset rather than 2 days before onset, should be regarded as close contact and centrally isolated in case of asymptomatic infection already existed in the family.
