Mycobacterium tuberculosis and HIV constitute a public health challenge. Health workers (HWs) in HIV clinics maybe at greater risk of M. tuberculosis infection, considering the high rates of HIV/tuberculosis (TB) coinfection among patients. Hence, we measured the prevalence of M. tuberculosis infection and the effect of working in an HIV clinic. We conducted a cross-sectional study in high-HIV burden health-care facilities in Abuja and Nasarawa states and recruited HWs over 4 months. We administered questionnaires and screened for M. tuberculosis infection using QuantiFERON-TB Gold-Plus. A total of 1,043 HWs were enrolled, with the majority being clinical staff (77.4%). Prevalence of interferon gamma release assay (IGRA) positivity was 44.8% (43.8% among HWs from HIV clinic and 45.3% from non-HIV clinics, P = 0.24). Nonoccupational factors such as living in a moderately (odds ratio [OR] = 0.71] or sparsely populated neighborhood (OR = 0.56), remained associated with a reduced risk of IGRA positivity, whereas male gender (OR = 1.37) and having high blood pressure (HBP) (OR = 1.52) remained associated with an increased risk after adjusting. Occupational factors such as length of career as a HW of 10 to 20 years (OR = 1.45) or 20 to 30 years (OR = 1.74) remained associated with an increased risk of IGRA positivity after adjusting. In a final multivariate model, the factors of age between 20 to < 30 years (OR = 0.61), having HBP (OR = 1.56), having a length of career as a HW of 10 to 20 years (OR = 1.66) or 20 to 30 years (OR = 2.09) and being a clinical HW (OR = 0.62) remained associated with IGRA positivity. There is a high prevalence of IGRA positivity among HWs in Nigeria. Working in HIV clinics, however, is not associated with increased risk.

The study was approved by the National Health Research Ethics Committee. Signed informed consent forms were administered prior to enrollment into the study and personal information was kept confidential. All study participants were informed of their QuantiFERON-TB Gold-Plus test result, and further testing and consultation were provided for those who accepted it.
