Risk of TB infection and room ventilation. The risk of TB infection for patients waiting an average of 3 h in a waiting room, or for a healthcare worker working for 6 h in a consulting room, is shown. TB risk was calculated using the room ventilation rate measured in each room either pre-intervention (blue triangles) or post- intervention to improve natural ventilation (red circles)
