#Airborne transmission from 20 ft distance after just 5 min of exposure. CCTV footage showed source patient (B) had no direct contact w/infected (B) seated 20 ft away, or (C) seated 14 ft away. AC unit may've aided airflow. NOTE: restaurant lacked windows & ventilation system.

Study highlights deficiency of current guidelines: "Transmission in an indoor setting is possible at a distance greater than 2m with a short period of exposure (5 minutes), and selection of close contacts in contact tracing should be changed. https://pubmed.ncbi.nlm.nih.gov/33258335/ 

*1st tweet should say source patient (B) was seated 20 ft away from infected patient (A) and 14 ft away from infected patient (C)
