Nature Communications, Published online: 21 May 2026; doi:10.1038/s41467-026-73470-w This study shows that increasing space per person from 2 to 32 m3 can dramatically reduce airborne infection risk from illnesses like COVID-19, even under poor ventilation. Updated ventilation and spaciousness standards are needed.
