Discussion Brief
Ventilation plays a key role in tuberculosis infection control, and in resource-poor settings good ventilation is often achieved by opening windows and letting the wind move the air in and out of the building. However, in some climates it is too cold to keep windows open, and this presents a problem for infection control.
A member working with Médecins Sans Frontières in Lesotho in an HIV program where 80% of patients are also diagnosed with TB wondered how health facilities operating without electricity can reduce nosocomial TB infections in cold climates where the most common heat source is charcoal stoves. Practical recommendations to improve ventilation and other infection control measures were shared.
