When in close quarters with someone infected with tuberculosis (TB), wearing special masks is essential for preventing the transmission of the bacterial infection. TB is primarily spread through the air when an infected person coughs, sneezes, or even talks, releasing droplets that contain the bacteria. The use of special masks, such as N95 respirators, is crucial as they provide a higher level of filtration compared to standard masks, effectively reducing the risk of inhaling the infectious particles. Other methods like keeping windows open could help improve ventilation, but they are not a substitute for the protective efficacy offered by specially designed masks. Frequent use of hand sanitizer is important for hand hygiene, but it does not address airborne transmission, which is the primary route for TB spread. Therefore, wearing special masks is the most effective precaution when in close proximity to someone with TB.
