Rapid Test for Recent Infection (RTRI) Surveillance Activities & Inventory Tool

Overview

The Rapid Test for Recent Infection (RTRI) is a pointofcare assay that can differentiate between recent and longstanding HIV infections. Coupled with a robust datacollection platform, the RTRI Surveillance Activities and Inventory Tool enables publichealth programs to monitor new transmission trends, allocate resources efficiently, and support targeted prevention interventions.

This page provides a concise guide to the purpose of RTRI surveillance, key activities, and how to use the webbased inventory system that tracks test kits, training sessions, and field data.

Why Use RTRI?

• Timely detection of recent infections: Results are available within minutes, allowing immediate publichealth action.
• Improved epidemic modeling: Distinguishing recent from chronic cases refines incidence estimates.
• Targeted outreach: Communities with rising recentinfection rates can receive focused education, testing, and treatment services.
• Costeffective: Onestep testing reduces laboratory workload and shortens turnaround time compared with traditional serological algorithms.

Surveillance Activities

1. Site Selection and Mapping

Identify highrisk geographic zones using existing HIV prevalence data, demographic indicators, and communityreporting mechanisms. Map these zones in the tool to allocate test kits and plan field visits.

2. Training & Capacity Building

Conduct a standardized 2day training for health workers covering sample collection, test execution, interpretation of results, data entry, and biosafety. Training records are uploaded directly into the inventory system.

3. Testing Protocol

1. Obtain informed consent and collect a fingerstick blood sample.
2. Apply the sample to the RTRI cassette according to the manufacturers instructions.
3. Read the result after the recommended incubation period (typically 15minutes).
4. Record the outcome Recent, LongTerm, or Invalid in the mobile data capture form.

4. Data Aggregation and Reporting

Daily uploads from field devices feed a central dashboard that displays:

• Number of tests performed per site.
• Proportion of recent infections.
• Geospatial heatmaps of recentinfection clusters.

5. Quality Assurance

Every month, a random 10% sample of tested kits is sent to a reference laboratory for verification. Results are logged in the tool to calculate concordance rates and trigger corrective actions if needed.

Inventory Tool Features

The system is hosted on a secure cloud server with endtoend encryption. Offline data entry is possible through the mobile app; once connectivity is restored, records sync automatically.

Getting Started

1. Register your organization: Visit Create Account and complete the registration form.
2. Define your inventory: Enter the initial quantity of RTRI kits, ancillary supplies, and storage locations.
3. Upload training data: After each training session, upload the participant list and certificates.
4. Begin testing: Field officers log in, select their assigned site, and record each test result as it occurs.
5. Monitor dashboards: Supervisors review weekly summaries, identify emerging clusters, and reallocate kits as needed.
