Highlights

  • We report a familial cluster of COVID-19 to assess potential transmission of the disease during the incubation period.

  • A familial cluster of four patients with COVID-19 in Zhoushan, China had contact with an asymptomatic family member, who developed symptoms later.

  • The infectivity during the incubation period for SARS-CoV-2 is a big challenge for controlling the disease.

Abstract

We report a familial cluster of 2019 novel coronavirus disease (COVID-19) to assess its potential transmission during the incubation period. The first patient in this familial cluster was identified during the presymptomatic period, as a close contact of a confirmed patient. Five family members had close contact with this first patient during his incubation period, with four of them confirmed positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the subsequent sampling tests.
