Diagnosing active tuberculosis based only on signs and symptoms is difficult, [99] as is diagnosing the disease in those who have a weakened immune system. [100] A diagnosis of TB should, however, be considered in those with signs of lung disease or constitutional symptoms lasting longer than two weeks. [100]
If there is any question of active TB, sputum smears must be obtained. Therefore, any applicant might have findings grouped in this category, but still have active TB as suggested by the presence of signs or symptoms of TB, or sputum smears positive for AFB. [2] The main chest X-ray findings that can suggest inactive TB are: [2] 1.
The medical history includes obtaining the symptoms of pulmonary TB: productive, prolonged cough of three or more weeks, chest pain, and hemoptysis.Systemic symptoms include low grade remittent fever, chills, night sweats, appetite loss, weight loss, easy fatiguability, and production of sputum that starts out mucoid but changes to purulent.

Mycobacterium tuberculosis is the most common cause of both pulmonary tuberculosis and tuberculous lymphadenitis. [1] [6] Historically, transmission of Mycobacterium bovis from dairy consumption was another frequent cause of tuberculous lymphadenitis, but incidence has drastically decreased in developed countries since the advent of pasteurization and other efforts to prevent bovine ...
Treatment of latent TB infection typically involves using a single drug for a prolonged period of time—the most common approach is Isoniazid for 9 months. Treatment of active TB disease is typically a combination of antibiotics, which results in patients being non-infectious to others usually within a few weeks.
Esmond R. Long and Florence B. Seibert identified the active agent in tuberculin as a protein. Seibert then spent a number of years developing methods for separating and purifying the protein from Mycobacterium tuberculosis, obtaining purified protein derivative (PPD) and enabling the creation of a reliable test for tuberculosis.

Health department says it is monitoring and working with family of patient “to persuade her to get the treatment she needs.”
Active tuberculosis begins when the bacteria starts developing, and the signs and symptoms begin to be visible. Although the TB bacteria can infect any organ (e.g., kidney, lymph nodes, bones, joints) in the body, the disease commonly occurs in the lungs. [9] Around 80% of all TB cases are related to pulmonary or lung.
