The new study discovered that this was far too conservative of an estimation, finding that the density of aerosol particles near individuals in a room can be 2.5 times more than experts had thought. According to Prof. Jimenez, the results of the study strongly depend on the geometry of the classroom and the airflow, but the studys message for schools is clear: We need sufficient ventilation in all classrooms to control the spread of the Delta variant. The others are precautions that may prevent some infections, but we dont know how important they are. This photo was taken on March 24th, 2020 at Carl Schurz Park, Morse was on the Brian Lehrer Show today, and actually answered this there.

In the midst of the Covid-19 crisis, public health officials in the U.S. are increasingly trumpeting the benefits of open windows and fresh air. Whole-house fans are typically used to provide cooling by pulling air through open windows and doors and exhausting it through the roof. To try to understand the risk of COVID-19 transmission at schools, the researchers from the Massachusetts Institute of Technology (MIT) simulated two different types of ventilation in a classroom: ceiling diffusers and open windows. When used along with other best practices recommended by CDC, operating the HVAC system can be part of a plan to protect yourself and your family.
