Background:
Knowledge of HIV-positive status may result in depressive symptoms, which may be a concern to scaling novel HIV testing interventions that move testing outside the health system and away from counselor support.
Setting:
Uganda and Zambia.
Methods:
We used longitudinal data from 2 female sex worker (FSW) cohorts in Uganda (n = 960) and Zambia (n = 965). Over 4 months, participants had ample opportunity to HIV testing using standard-of-care services or self-tests. At baseline and 4 months, we measured participants' perceived knowledge of HIV status, severity of depressive symptoms (continuous PHQ-9 scale, 0-27 points), and prevalence of likely depression (PHQ-9 scores ≥10). We estimated associations using individual fixed-effects estimation.
Results:
Compared with unknown HIV status, knowledge of HIV-negative status was significantly associated with a decrease in depressive symptoms of 1.06 points in Uganda (95% CI -1.79 to -0.34) and 1.68 points in Zambia (95% CI -2.70 to -0.62). Knowledge of HIV-positive status was significantly associated with a decrease in depressive symptoms of 1.01 points in Uganda (95% CI -1.82 to -0.20) and 1.98 points in Zambia (95% CI -3.09 to -0.88). The prevalence of likely depression was not associated with knowledge of HIV status in Uganda but was associated with a 14.1% decrease with knowledge of HIV-negative status (95% CI -22.1% to -6.0%) and a 14.3% decrease with knowledge of HIV-positive status (95% CI -23.9% to -4.5%) in Zambia.
Conclusions:
Knowledge of HIV status, be it positive or negative, was significantly associated with a decrease in depressive symptoms in 2 FSW populations. The expansion of HIV testing programs may have mental health benefits for FSWs.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
