Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, [7] is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs , but it can also affect other parts of the body. [ 1 ]
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 ...
Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into the human body and by the tiny size of the lesions (1–5 mm). Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the term "miliary" tuberculosis.
The risk of chronic diseases increased with age and, in some cases, was exacerbated by unhealthy lifestyles. Cancer and heart disease shot up across the century, increasing 90-fold from 1900 to ...
Other parts of the medical history include prior TB exposure, infection or disease and medical conditions that increase risk for TB disease such as HIV infection. Depending on the sort of patient population surveyed, as few as 20%, or as many as 75% of pulmonary tuberculosis cases may be without symptoms.
In fact, death from tuberculosis was greater in diabetic patients. [9] Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "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 ...
Tuberculosis is back to being the leading infectious disease killer across the globe, surpassing COVID-19, according to a recent report from the World Health Organization.. Nearly 8.2 million ...
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 ).
