Ndola: Average number of couples per month that received weekday couples voluntary counseling and testing in clinics with at least two years of data.

<p>Blue bar represents CVCT provided by on-duty government counselors in the ANC clinics; orange bars represent CVCT provided by on duty government counselors in the VCT department; grey bar represents weekday CVCT provided by a ZEHRP-sponsored counselor. Grey stars indicate clinic-years when no ZEHRP-sponsored staff provided CVCT services. Blue stars indicate clinics in which logbooks for data extraction were not available for that year.</p

Number and percent of first time ANC clients and partners tested 2009–2015, from HMIS reports to DHMT in Ndola.

<p>Blue represents women whose partners were not tested, orange represents women whose partners were tested. Percentage of ANC clients with male partner tested is shown above each bar.</p
