Background The clock is steadily ticking towards 2020 when the UNAIDS 90-90-90 global target in the fight against HIV/AIDS is hoped to be achieved. The hypothesis tested is the significant association between youthful age and HIV test outcome. The aim of the study was to engage in an accelerated HIV case finding and ensure enrolment into care among key populations in Western Nigeria fulfilling the first & second 90 of the UNAIDS targets.

Methods Lay Adhoc Staff/volunteers were purposely selected and trained. Consenting prison inmates had their blood samples taken and tested following the country’s HIV serology National testing algorithm, using the recommended HIV testing kits. Those who tested positive went through a retesting process in the laboratory and confirmed positive. Post-test counselling was then conducted.

Results A total of 771 prison inmates were tested across the four prisons (Male 765, Female 6) with a mean age ± SD is 31.25 ± 9.47 years. Ten of them (Male 9, Female 1) were confirmed new positives with a mean age ± SD is 31.40 ± 6.24 years, yielding a positivity rate of 1.3%. Eight of the ten positives are in their youthful age (<35 years). Odd’s ratio shows that youthful age have higher association with HIV test outcome (OR: 2.81, CI: 0.80–9.79). The linkage rate for the positives is 100% with good escort service while adherence is ≥ 95%.

Conclusion This mode of HIV testing service (HTS) has proved to reach a key population yielding more positives in much fewer numbers of people tested and in a short period of time with 100% linkage with better resource/health financing outlook. Community ART Differentiated Service Delivery (DSD) Model is in line for the patients to sustain the gains in the effort to achieve the 90-90-90 fast track UNAIDS targets.
