In collaboration with YMCA in Spain, we have carried out a study on the ventilation of camping tents as a means of assessing the risks of aerosol transmission of COVID-19.

Our conclusion is that properly ventilated camping tents with two occupants may offer comparable safety levels to those of very well ventilated dormitory rooms with eight or more occupants.

Proper ventilation often entails opening additional ventilation inlets and outlets to those already built into the tent. For Canadian-type tents, sufficient ventilation may be achieved by partially rolling up the side flaps; igloo-type tents are less COVID-19-safe, and adequate ventilation may require partially or totally opening the tent doors.
