Flu Exposure Study Finds No Transmission in Shared Room, Highlights Masks and Airflow
A small study exposed five flu-infected participants to 11 healthy volunteers in a poorly ventilated hotel room. Surprisingly, none of the healthy participants became sick, a result researchers attribute to factors like prior immunity in middle-aged adults, a mild flu season, and limited coughing; the study reinforces the value of good airflow and masks in reducing flu spread.
