However, most infections with M. tuberculosis do not cause disease, [169] and 90–95% of infections remain asymptomatic. [87] In 2012, an estimated 8.6 million chronic cases were active. [170] In 2010, 8.8 million new cases of tuberculosis were diagnosed, and 1.20–1.45 million deaths occurred (most of these occurring in developing countries).
Symptoms of M. tuberculosis include coughing that lasts for more than three weeks, hemoptysis, chest pain when breathing or coughing, weight loss, fatigue, fever, night sweats, chills, and loss of appetite. M. tuberculosis also has the potential of spreading to other parts of the body. This can cause blood in urine if the kidneys are affected ...
[19] [20] Globally, the severe malnutrition common in parts of the developing world causes a large increase in the risk of developing active tuberculosis, due to its damaging effects on the immune system. [21] [22] Along with overcrowding, poor nutrition may contribute to the strong link observed between tuberculosis and poverty. [23] [24]
Tuberculosis is a disease caused by a bacterium called Mycobacterium tuberculosis, per the CDC. Tuberculosis spreads through the air from one person to another. Someone with an active infection ...
"HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death globally for HIV-infected people." [10]
Tuberculosis, or TB, is a disease that usually affects the lungs but can affect other parts of the body. It can live in the body without making you sick or causing any symptoms but can discovered ...
Epiglottitis is a bacterial infection of the larynx which causes life-threatening swelling of the epiglottis with a mortality rate of 7% in adults and 1% in children. [10] Haemophilus influenzae is still the primary cause even with vaccinations. Also Streptococcus pyogenes can cause epiglottitis.
Because MDR tuberculosis is an airborne pathogen, persons with active, pulmonary tuberculosis caused by a multidrug-resistant strain can transmit the disease if they are alive and coughing. [41] TB strains are often less fit and less transmissible, and outbreaks occur more readily in people with weakened immune systems (e.g., patients with HIV ).
