Article Synopsis
- The study focused on karaoke-related COVID-19 outbreaks to identify risk factors for SARS-CoV-2 infection among karaoke participants.
- It involved a case-control approach, where 81 infected individuals (mostly elderly) were compared with non-infected individuals from the same karaoke bar.
- Key findings indicated that singing, not wearing a mask, and spending more time in the bar significantly increased infection risks, highlighting that less-ventilated indoor spaces pose a greater threat for virus transmission.
