Cluster of Severe Acute Respiratory Syndrome Coronavirus 2 Infections Linked to Music Clubs in Osaka, Japan.

ABSTRACT:

Background

It is important to understand the mode of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for disease control. We aimed to clarify how soon SARS-CoV-2 transmission can occur after infection by asymptomatically infected individuals.

Methods

Results

Among cases, 51 cases attended a live music club only once and were considered to have a single visit.

Three routes of secondary transmission were identified, with 2-4 days from inf
