The investigators will evaluate the impact of the intervention using a linked data set including electronic clinic records and the HDSS census data, which will allow us to determine whether people in the intervention communities test at higher proportions than those in control communities, whether individuals who test positive in the intervention communities are more likely to receive CD4 testing and initiate treatment within 3 months than the control communities, and whether those who are eligible and not eligible for treatment are still in care 12 months after diagnosis.
