UNIDENTIFIED FEMALE: When people, if they get in coughing I roll the windows down in the back a little bit and kind of you know circulate the air around the car.
Their thick masonry walls insulated against the heat, and the vertical air shafts between the buildings give at least some airflow to stifling tenement rooms.
Check your ventilation and keep the air circulating, make sure everyone has a mask on if you're outdoors and cannot maintain a six foot distance or anytime you're indoors with people who are not in your immediate household.
