Tuberculosis is increasing in many countries.
In some areas the major influences on tuberculosis trends are the traditional ones : poverty, failures in the treatment system, and immigration.
In others, and increasingly, the HIV epidemic is having a huge impact.
HIV infection increases the risk of tuberculosis approximately 7-fold, though this may vary with the stage of the HIV epidemic, the prevalence of tuberculosis, and the age groups considered.
Dually-infected individuals develop tuberculous disease at a rate of 5-10% per year.
HIV also increases the risk of disease following recent infection, which makes a major contribution to the tuberculosis burden in some settings.
HIV-infected individuals may transmit Mycobacterium tuberculosis less than do HIV-negative individuals, but the extra cases will add to the transmission overall, and evidence of HIV-attributable increases in the annual risk of infection is beginning to be seen.
