The HIV infection case relates to an extrapulmonary TB. Nine cases of diabetes were diagnosed [5.8% (3.1 - 10.6)], and four of them had their diabetes status before the study. Six diabetic are between 40 and 50 years. Among TB patients, diabetes prevalence is nine times higher than HIV prevalence (P = 0.01).Conclusion:As for people living with HIV, diabetics should benefit TB prevention and routine screening of TB.
