a HIV, human immunodeficiency virus; PITC, provider initiated testing and counseling; HBHTC, home-based HIV testing and counseling; VBHTC, venue-based HIV testing and counseling. aAll HIV-positive clients were screened to assess their new or prior diagnostic status. HIV-positive clients who reported having never previously tested HIV-positive were defined as newly HIV diagnosed. PITC began in Q4 2014 in seven of 11 health facilities and was implemented in all 11 facilities during Q1 2015 –Q1 2017. HBHTC teams visited all Bukoba Municipal Council (BMC) households on the mainland and offered HIV testing to encountered persons during Q1 2015 –Q2 2016. HBHTC was not conducted during Q3 2016. In Q4 2016, HBHTC teams visited all homes and offered HIV testing on two BMC islands. In Q1 2017, HBHTC was restricted to home clusters on the mainland that included partners and family members of persons diagnosed during VBHTC events. VBHTC was conducted on the mainland from Q4 2014 –Q1 2017 and on the islands in Q4 2016. VBHTC was conducted primarily in urban wards during Q4 2014 –Q3 2015, rural wards during Q4 2015 –Q1 2016, and urban wards Q2 2016 –Q1 2017. Proportion newly diagnosed was calculated by dividing counts of newly diagnosed clients by total HIV tests conducted for that quarter (Fig 2).
