Despite several years of medical advances the worldis still a long way from exorcizing the medical demon of tuberculosis. When considering the worldwide scenario, nine million new cases are diagnosed annually and at least 1.5 million people succumb to the disease every year. Several reasons were stated in support of failure to curb the disease, like the lack of investment into diagnostic tools and treatment, persisting poverty, lack of access to medical care, increase in drug-resistant strains of TB, crowded living conditions and the most leading cause is the spread of HIV, the virus that causes AIDS. Infection with HIV suppresses the immune system, making it difficult for the body to control TB bacteria.
