Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions".

There is a popular misconception that tuberculosis is purely a disease of the lungs that manifests as coughing. [47] Tuberculosis may infect many organs, even though it most commonly occurs in the lungs (known as pulmonary tuberculosis). [8]

Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB). Almost one in four people in the world is infected with TB bacteria. [1]

An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
