Extensively drug-resistant tuberculosis, or XDR-TB, is an even more severe category, showing resistance to fluoroquinolones and at least one of the second-line injectable drugs. Individuals with compromised immune systems, such as those living with HIV, are at a much higher risk of developing active disease from a latent infection.

Risk Factors and Transmission Dynamics Understanding the types of tuberculosis also involves recognizing who is at risk and how transmission occurs. This transition from latent to active is the primary gateway to developing the various symptomatic forms of the disease.
Close contact with an active pulmonary TB case is the primary mode of transmission. This complex interplay between the pathogen, the environment, and the host immune response dictates the clinical presentation and type of tuberculosis that emerges.
Extrapulmonary Tuberculosis Types and Symptoms by Location
This poses a significant treatment challenge, requiring longer, more expensive, and more toxic second-line drug regimens. Common manifestations include lymphadenitis (swollen lymph nodes), often in the neck; tuberculous meningitis, which affects the membranes surrounding the brain and spinal cord; and skeletal tuberculosis, frequently targeting the spine (Pott's disease).
