One of the social diseases nowadays in Russia is tuberculosis. Incidence of tuberculosis is higher in areas with large population. Men are affected more often than women. The greatest number of cases occurs in little children. Socially and economically disadvantaged, alcoholics, malnourished individuals are affected more often.
Scrofula is an old-fashioned name for tuberculosis (TB). It is a bacterial infectious disease. The disease affects the lymph nodes, especially those in the neck. Symptoms include swelling of the glands and the development of abscesses. Tuberculosis may also affect other organs

but the most common form is pulmonary tuberculosis, which attacks the lungs.
The causative bacterium is Mycobacterium tuberculosis. It is a droplet infection which usually passes from person to person. It is spread via airborne droplets when an infected person coughs or sneezes. Once inhaled, the organisms implant themselves in the lungs and begin to divide. Overcrowded living conditions provide long-term environment for the infection to spread.
There is another way of transmission. A strain of tuberculosis affecting cattle can transfer to their milk and infect people drinking it. In Britain pasteurization of milk kills the bacterium but worldwide unpasteurized milk is a common source of infection.
Pulmonary tuberculosis occurs in two phases. In the primary phase the infection occurs in different parts of the body. The victim may develop a dry cough that lasts for 3 to 4 months. The secondary phase occurs with increasing age and/or worsening of patient’s health. At this stage the causative bacterium is activated and attacks the lungs. Violent, frequent coughing brings up phlegm which may be tinged with blood. Other clinical manifestations include anorexia, weight loss, low-grade fever, chills and night sweats.
To diagnose the disease a chest X-ray is made, sputum cultures are obtained. A sputum culture identifying Mycobacterium tuberculosis confirms the diagnosis. After the medications are started, sputum samples are obtained again to determine the effectiveness of the therapy.
Mantoux test is the most reliable determinant of tuberculosis infection. A positive reaction doesn’t mean that active disease is present but indicates exposure to tuberculosis or the presence of inactive disease. Once the test result is positive, it will be positive in any future tests. When Mantoux test is positive, a chest X-ray is necessary to rule out active tuberculosis or to detect old healed lesions.

The reduction in overcrowding at home, improvement in hygiene and diet, the development of antibiotics and an effective safe vaccine have reduced mortality dramatically. However, each year new cases are reported especially in poor developing countries, as well as in Russia.
The goal of treatment is to prevent transmission, control symptoms, and prevent progression of the disease.
