Bathrooms are a concern—because of toilet plumes. “Because a flush can release plume of aerosolized droplets in the air—and we know #SARSCoV2 can be spread in fecal matter—encountering toilet plumes from others may put you at risk for #COVID19.” @NatBCo https://www.washingtonpost.com/travel/tips/road-trip-rest-stop-covid/

2) “Often people get a false sense of security because if they go into a bathroom & don’t see anyone else, they think they’re safe. But we know aerosols can stay in the room for anywhere from 20 min to 4 hours. It depends on ventilation, & often bathrooms have poor ventilation.”

4) What really irks me is that there is almost never a toilet lid in public bathrooms in the US. Goto Europe and Asia—most of the time you’ll find toilet lids. It’s like a mask for a toilet. And US just doesn’t have enough toilet masks. Oy.
