How is tuberculosis primarily transmitted?

Tuberculosis (TB) is primarily transmitted through airborne droplets from an infected person. When a person with active tuberculosis coughs, sneezes, sings, or talks, they release tiny droplets containing the bacteria Mycobacterium tuberculosis into the air. Others can inhale these droplets, leading to infection. This method of transmission is highly effective in close-contact settings, making it crucial to understand and implement infection control practices in healthcare and community settings to prevent the spread of this serious disease.

The other options do not accurately reflect the primary method of TB transmission. Contaminated water sources and sharing personal items are not typically associated with the spread of TB, as the bacteria are not viable in water and cannot be transmitted through indirect contact. Direct contact with skin lesions may pertain to other infections but is not a concern for tuberculosis, which primarily affects the respiratory system and is transmitted through inhalation. Understanding the airborne nature of TB transmission is vital for effective public health measures and personal prevention strategies.
