Introduction
The most commonly used disinfection method in tuberculosis wards is ultraviolet (UV) disinfection. For example, opening windows to ventilate the room allows natural UV radiation from outdoor sunlight to disinfect the air, effectively killing airborne *Mycobacterium tuberculosis*. In the absence of sunlight, UV disinfection can still be performed on cloudy days, or chlorine-containing disinfectants can be sprayed to effectively decontaminate bedding.

    Patients with pulmonary tuberculosis spread *Mycobacterium tuberculosis* via airborne droplets generated during speaking, laughing, or exhaling. This is a chronic infectious disease caused by *Mycobacterium tuberculosis*. Infection does not occur when an individual possesses robust natural immunity. However, individuals with compromised immune function are highly susceptible to infection. So, how should a room occupied by a pulmonary tuberculosis patient be disinfected?

How to Disinfect a Room Occupied by a Pulmonary Tuberculosis Patient

The most commonly used disinfection method in tuberculosis wards is ultraviolet (UV) irradiation. For instance, opening windows for ventilation allows natural outdoor UV light from sunlight to disinfect the air, effectively killing airborne *M. tuberculosis*. In the absence of direct sunlight—such as on overcast days—artificial UV lamps may be employed for disinfection. Alternatively, chlorine-containing disinfectants can be sprayed to eliminate *M. tuberculosis* on bedding and floor surfaces. Additionally, peracetic acid may be used for air disinfection. Therefore, specific disinfection protocols for tuberculosis wards must strictly adhere to established guidelines and standards.

Tuberculosis is primarily transmitted via respiratory droplets; thus, prompt disinfection of the patient’s living environment is essential. Comprehensive room disinfection must cover every corner to ensure thorough decontamination.

In daily life, maintain a regular, balanced diet—avoid spicy, irritating foods and overeating, and refrain from staying up late. We hope this information is helpful to you.
