Study Notes
- Tuberculosis is an infectious disease typically caused by Mycobacterium tuberculosis bacteria.
- It affects the lungs, but can also impact other body parts, including about 1 in 5 cases where the infection is extrapulmonary.
- Most tuberculosis infections are asymptomatic, known as latent tuberculosis; about 10% of these progress to active disease, which can be fatal if left untreated.
- The disease is primarily spread through the air when people with active infections cough, sneeze, speak, or spit.
- People with HIV/AIDS and smokers are more likely to develop active tuberculosis infections.
- Approximately 60% of patients with extrapulmonary manifestations of tuberculosis have no evidence of pulmonary infection on chest radiographs or in sputum cultures.
- Symptoms of active pulmonary tuberculosis include: persistent cough, chest pain, unexplained weight loss, and fever.
- Extrapulmonary involvement can manifest in various ways, including ocular, urinary, skeletal, neurological, cardiac, peritoneal, cutaneous, and more.
- Tuberculosis can be fatal if untreated, with about half of those affected by active disease dying.
- Tuberculosis can be spread through the air when infected individuals cough, sneeze, speak, or spit.
- People with latent tuberculosis do not spread the disease.
- People with HIV/AIDS and smokers are more susceptible to developing active tuberculosis.
- Extrapulmonary involvement in tuberculosis occurs in one fifth of all cases.
- Approximately 60% of patients with extrapulmonary manifestations of tuberculosis have no evidence of pulmonary infection on chest radiographs or in sputum cultures.
