TB prevalence, illness and deaths are very much more common in the low- and middle-income countries than high-income countries. However the higher rate of TB in low- and middle-income settings, especially in people with HIV, has meant that large TB studies have tended to be conducted there, and in some ways we know less about TB in high-income settings, especially in people with HIV.
People diagnosed with HIV in high-income countries, especially if they do not come from areas with high HIV and/or high TB prevalence, are less systematically tested for TB and so won’t get the opportunity to take TB prevention drugs if they have latent TB.
