Pretty interesting report of #Covid19 transmission during church services in Australia. Infected choir member appears to have transmitted to up to 12 church goers, some seated more than 15 meters from the choir loft. No masks. Yes, likely airborne. wwwnc.cdc.gov/eid/article/27… pic.twitter.com/Wmi6jxOPox

Here's our report on a #COVID19 cluster in a church in Sydney. We think transmission is best explained by airborne spread, likely facilitated by singing + low ventilation + a primary case near peak infectiousness. 1/2 wwwnc.cdc.gov/eid/article/27… pic.twitter.com/g14eF0HpIB

Interesting that the index case in the Australia church outbreak was 18. @paulchenz has demonstrated that viral shedding is shorter in young people...that's likely why there was trans on symptom day -2 and -1, and not on 0...his VL was likely already down.wwwnc.cdc.gov/eid/article/27…

Add it to the list - choir, spin class, gym, hockey locker room, restaurant, bus... Same factors, every time: --> indoors --> no masks --> low/no ventilation "the ventilation system at the apex was not in operation during the services." wwwnc.cdc.gov/eid/article/27…

“Video recordings showed that (the 12!) case-patients were seated >15 m from the primary case-patient, without close physical contact, suggesting airborne transmission” - Airborne Transmission of SARS-CoV-2 during Singing wwwnc.cdc.gov/eid/article/27…
