Transfusion Transmissible Infection (TTI) Screening & Hepatitis B Virus (HBV) Surveillance
Wajir County Blood Safety & Infection Prevention Programme (Kenya)
A high-impact infection prevention and blood safety surveillance programme addressing severe and previously under-reported Hepatitis B Virus (HBV) burden in Wajir County, transforming passive screening into an active IPC-led blood safety and epidemiological intelligence system.
Project Background
Wajir County carries a significantly high and largely hidden Hepatitis B burden, with HBV positivity rates reaching up to 10.7%, more than ten times the WHO safe threshold for blood donors.
Prior to this intervention, there was no structured surveillance system, no donor follow-up mechanism, and no integrated infection prevention response for transfusion-transmissible infections.
This project transformed blood screening from a passive testing activity into a fully functional IPC-led surveillance system capable of detecting trends, notifying reactive donors, and informing national policy.

Project Objectives
Improve Blood Safety
Strengthen transfusion safety through systematic TTI screening and surveillance.
HBV Surveillance
Monitor and analyze Hepatitis B trends among blood donors in Wajir County.
Donor Notification System
Ensure timely notification and referral of reactive donors.
Evidence Generation
Generate actionable epidemiological data for county and national response.
