Tuberculosis Exam Questions and
Answers 100% Solved | Graded A+
Tuberculosis - ✔✔is an infectious disease usually caused by the bacterium
Mycobacterium tuberculosis (MTB).[1] Tuberculosis generally affects the
lungs, but can also affect other parts of the body. Most infections do not
have symptoms, known as latent tuberculosis. About 10% of latent
infections progress to active disease which, if left untreated kills about half
of those infected. The classic symptoms of active TB are a chronic cough
with blood-containing sputum, fever, night sweats, and weight loss.[1] The
historical term "consumption" came about due to the weight loss.[2]
Infection of other organs can cause a wide range of symptoms.[3]
Tuberculosis is spread through the air when people who have active TB in
their lungs cough, spit, speak, or sneeze.[1][4] People with latent TB do not
spread the disease. Active infection occurs more often in people with
HIV/AIDS and in those who smoke.[1] Diagnosis of active TB is based on
chest X-rays, as well as microscopic examination and culture of body fluids.

, Diagnosis of latent TB relies on the tuberculin skin test (TST) or blood
tests.[5]
Prevention of TB involves screening those at high risk, early detection and
treatment of cases, and vaccination with the bacillus Calmette-Guérin
vaccine.[6][7][8] Those at high risk include household, workplace, and
social contacts of people with active TB.[8] Treatment requires the use of
multiple antibiotics over a long period of time.[1] Antibiotic resistance is a
growing problem with increasing rates of multiple drug-resistant
tuberculosis (MDR-TB).[1]
One-third of the world's population is thought to be infected with TB.[1] New
infections occur in about 1% of the population each year.[9] In 2014, there
were 9.6 million cases of active TB which resulted in 1.5 million deaths.
More than 95% of deaths occurred in developing countries. The number of
new
Signs and symptoms - ✔✔Tuberculosis may infect any part of the body, but
most commonly occurs in the lungs (known as pulmonary tuberculosis).[3]
Extrapulmonary TB occurs when tuberculosis develops outside of the
lungs, although extrapulmonary TB may coexist with pulmonary TB.[3]
