Which method is used to kill airborne pathogens like tuberculosis (TB)?

Using UV lights is an effective method for killing airborne pathogens, including tuberculosis (TB). Ultraviolet (UV) light works by disrupting the DNA of microorganisms, rendering them unable to replicate and effectively neutralizing them. This method is particularly useful in settings like hospitals or clinics, where the risk of airborne transmission of infectious diseases is a concern. UV lights can be installed in areas where air circulation is managed, ensuring that the air coming into contact with the UV light is treated and pathogens are eliminated, providing a safer environment for patients and healthcare workers.

Other methods, while useful for different purposes, do not specifically target airborne pathogens in the same efficient manner. For instance, air filtration systems can capture airborne particles but may not eliminate all pathogens. Chemical disinfectants are effective for surfaces but are not designed for airborne applications. Heat sterilization is primarily used for instruments and surfaces rather than for treating air.
