Social and Economic Impact of tebibyteIntroductionOverviewTuberculosis is a joint and pathogenic communicable disease that is caused by mycobacterium tuberculosis. It is of two principle kinds pneumonic TB, which usually attacks the lungs, and extra-pulmonary TB, which attacks any part of the body, such as the lymphatic, pleural, bone and/or joint, genitourinary, miliary, peritoneal, meninges and/or central nervous system (CNS), and all other sites combined. Pulmonary TB sometimes combined with extra pulmonary tuberculosis (Parimon, 2008 Sreeramareddy et al., 2008 Friedman, 2001).Tuberculosis is spread in form of droplets which are expelled when the infected persons cough, sneeze, speak, or sing. Close, prolonged, frequent, or intense contacts are the main ways that leads to 22% of the infection rate. Other resources let in foreign-born from areas where TB is common, residents and employees living in plagued congregate settings, health care workers who serve severely infected cli ents, low-income populations, highly inflicted racial or ethnic nonage populations, children exposed to severely infected adults, and persons who inject illicit drugs.Extra pulmonary TB that occurs outside the lungs may spread through lymphatic or hematogenous public exposure to any tract or through coughing and swallowing to the gastrointestinal tract. Such a type of bacteria may remain dormant for years at a particular site before causing the disease. Since extra pulmonary TB can affect virtually all organs, it has a wide word form of clinical manifestations. A matter which causes difficulty and delay in its diagnosis (Mehta, 1991 Gonzalez et al., 2003). Though, it is said to be more often diagnosed in women and young patients (Rieder et al., 1990 Gonzalez et al., 2003 Yang et al., 2004 Noertjojo et al., 2002 Cowie and Sharpe, 1997 Antony et al., 1995 Chan-Yeung et al.,2002). In the join States, extra pulmonary TB is associated with ethnic minorities and with those born in othe r countries (Rieder et al., 1990) while in Asia, lymphatic TB occupies the front position of the risky infectious diseases (Cowie and Sharpe, 1997, 1998 Moudgil and Leitch, 1994 Nisar et al., 1991 Ormerod, et al., 1991). A study of Somali TB patients in Minnesota showed frequent lymphatic TB as well (Kempainen, et al., 2001). In HIV-infected patients, the frequency of extra pulmonary TB depends on the degree of decrease in cellular immunity (Huebner and Castro, 1995 Barnes, et.al., 1991). While in patients with
