Scientists focus on role of ventilation in preventing tuberculosis transmission

Scientists studying the role of room ventilation in tuberculosis transmission found that students in Cape Town, South Africa, spend almost 60 percent of their day in poorly ventilated rooms, at risk of transmission, according to results published May 7, 2014, in the open access journal PLOS ONE by Eugene Richardson from Stanford University School of Medicine and colleagues. The researchers propose an increase in low-cost, WHO-compliant natural ventilation to facilitate healthy indoor environments and reduce risks.
