2011• Hepatitis unit created

within RBC

• National TWG created• Viral load testing

introduced in 1st facility

2012

2013• Guidelines for prevention and

treatment• ROFAH created• Screening introduced at 2 facilities• Treatment available at 4 referral

centers

• Guidelines updated• National Policy adopted• NOP developed • HCWs trainings• Media coverage WHD activities• Price negotiations with pharmaceutical

companies• Limited coverage of treatment by health

insurances• First patient’s treated with SOF/Ribavirin

2015

2016• Sensitizing high risk groups• Screening of ~117,000

PLHIV• ELISA used at 13 sites• 1st patients treated with

SOF/LDV • Standardized patient file

introduced

2017-2018• Campaigns: ~438k

people screened and ~427k vaccinated

• Screening: remaining ~26k PLHIV and high risk population like prisoners, FSW and MSM

• 1st patients treated with SOF/DCV

• 8505 patients treated (SOF/LDV &SOF/DCV)

Methodology

8

✓ Screening targeted individuals:

✓ aged >45 years in lower socio-economic groups

✓ FSWs

✓ Diabetics

✓ HCWS

✓ Sensitization done through multimedia announcements and local church leaders

✓ Healthcare workers introduced and trained in VH screening, diagnosis and patient

counseling

✓ Sample testing for HBV & HCV using Murex Elisa (Spe:100%, Se: 99.9%)

✓ Bivariate and multivariate logistic regressions used to assess factors associated

with HBSAg and HCVAb positivity

Conclusion

✓ Results from the campaign serve as preliminary evidence

for variations in prevalence across different populations.

✓ Rwanda’s experience serves as important evidence for

other low and middle-income countries.

✓ campaign results will be used to plan national services for

future integration and decentralization of screening into

routine care at lower-level health centers.
