What is a preventive measure for tuberculosis patients to limit the spread?

The choice of using disposable tissues as a preventive measure for tuberculosis patients is crucial in limiting the spread of the disease. Tuberculosis (TB) is predominantly transmitted through airborne droplets when an infected person coughs, sneezes, or even speaks. When a TB patient uses disposable tissues, it effectively captures respiratory secretions that may contain the bacteria, decreasing the likelihood of aerosol transmission to others. This practice promotes hygiene and helps contain any potential pathogens, making it an essential part of infection control strategies.

Outdoor activities can be beneficial for overall health and fresh air circulation but may not directly prevent the spread of TB in crowded or enclosed spaces. Exercising indoors doesn't inherently address the risk of airborne transmission, especially if the ventilation is poor. Regular hand washing is vital in general infection control, particularly for preventing the spread of viruses and bacteria, but it does not specifically target the transmission route of tuberculosis, which is primarily respiratory. Therefore, using disposable tissues stands out as the most effective preventive measure in this context.
