Impact of the COVID-19 pandemic on regional and national uptake of HIV testing services in Sierra Leone: a descriptive analysis
Bibliographic record
Abstract
Abstract Background A key milestone in the reduction of the global HIV burden is reaching the UNAIDS 95-95-95 target by 2025. The COVID-19 pandemic may have affected the ability of countries to achieve this target, but data to describe this impact is limited. This study assessed national HIV testing service uptake in Sierra Leone during three periods of the COVID-19 pandemic. Methods We conducted a retrospective cross-sectional study using secondary program data of all patients tested for HIV in all 16 districts of Sierra Leone. Data from March 2019 to February 2020 (pre-COVID-19); March 2020 to February 2021 (during COVID-19); and March 2021 to February 2022 (post-COVID-19) were extracted from DHIS-2 and descriptive analyses were performed using Stata (15.1, StataCorp LLC, College Station, TX). Results The median number of HIV tests was 58,588 (IQR 54,232 to 62,077) in the pre-COVID phase, 55,141 (IQR 52,975 to 57,689) during the COVID-19 phase, and 74,954 (IQR 72,166 to 76,250) in the post-COVID phase. This shows that HIV testing rate decreased by 6.3% during the COVID-19 period and increased substantially by 36.0% in the post-COVID-19 period. Twice more women than men were tested for HIV across all periods—pre-COVID-19 (38,825 vs. 19,789), during COVID-19 (36,923 vs. 17,755), and post-COVID-19 (49,205 vs. 25,472) phases. Conclusion Our study shows that HIV testing was significantly disrupted during the COVID-19 pandemic but recovered quickly after the pandemic. These findings highlight that lessons learned from previous epidemics may influence adaptive strategies to maintain essential health services during public health emergencies.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
