Design outcomes

Primary

MeasureTime frame
We expect to find higher rates MDR transmission to women than men compared with non-MDR transmission.Timepoint: Baseline

Secondary

MeasureTime frame
We expect women exposed to MDR to have higher rates of malnutrition & HIV than women exposed to non-MDR-TB, & men exposed to MDR. We expect a higher rate of latent and/or active TB among women contacts of MDR compared with women exposed to non-MDR.Timepoint: Baseline, Year 1, Year2
