Overview
HIV is the main reason for failure to meet Tuberculosis (TB) control targets in high HIV settings. In spite of fewer people in USA suffering with TB, it remains a serious threat, especially for HIV-infected persons. In fact, worldwide TB is one of the leading causes of death among people infected with HIV. It is estimated that about 4.2% of Americans, with or without HIV infection, are infected with TB bacteria. People infected with HIV are more likely than uninfected people to get sick with other infections and diseases.
Risk Factors
The risk of developing tuberculosis (TB) is estimated to be between 20-37 times greater in people living with HIV than among those without HIV infection. In 2009, there were 9.4 million new cases of TB, of which 1.2 (13%) million were among people living with HIV. Of the 1.7 million people who died of TB, 400 000 (24%) were living with HIV. TB is a leading cause of morbidity and mortality among people living with HIV.
