Tuberculosis (or TB) is an infectious disease, usually caused by Mycobacterium tuberculosis bacteria. [1] TB generally affects the lungs, but can also affect other parts of the body. [1]
Most people affected by TB do not have symptoms, and the disease is not active. This is called latent tuberculosis. [1] However, about 10% of latent infections progress to active disease, which, if left untreated, kills about half of those affected. [1]
The classic symptoms of active TB are a chronic cough, with blood containing sputum, a fever, night sweats, and weight loss. [1]
The last symptom of weight loss can be so pronounced that it gave TB it historic name of "consumption". [3]
Infection of other organs can cause a wide range of symptoms, including weakness, night sweats, and swollen lymph nodes. [4]
Active TB in the lungs is very contagious. In fact, it is so infectious that a person can spread it through the air, by something as simple as coughing, spitting, speaking or sneezing. [1] [5]
And active infection is more likely to occur in people with HIV or AIDS, those who are immunocompromised, and in those who smoke. [1]
On the other hand, people with latent TB do not spread the disease. [1]
Diagnosis of active TB is based on chest X-rays, as well as microscopic examination, and culture of body fluids. [6]
Diagnosis of latent TB is made using the tuberculin skin test (which is also called the Mantoux skin test), or blood tests. [6]
Prevention of TB involves screening those at high risk, early detection and treatment of cases, and prompt vaccination with the bacillus Calmette-Guérin (BCG) vaccine. [7] [8] [9] Those at high risk include household, workplace, and social contacts of people with active TB. [9]
Treatment requires the use of multiple antibiotics, over a long period of time. [1] Antibiotic resistance is making TB harder to treat, with increasing rates of multiple drug-resistant tuberculosis (called MDR-TB), and extensively drug-resistant tuberculosis (called XDR-TB). [1]
