Nigeria – TB detection among children with Delft Light & CAD4TB
Children aged 5-14 account for 12% of Nigeria’s TB burden. Under diagnosis and low treatment coverage in children are significant challenges.
Deployed to 8 states for TB ACF
The Delft Light & CAD4TB were used for active TB case finding during community outreaches.
Using ultra-PDX with CAD4TB
At-risk children (5 years and above) were screened using the ultra-portable X-ray with CAD4TB.
Parallel screening algorithm
Presumptive TB was identified using the WHO four-symptom screen and a CAD4TB score above 50.
Bacteriological evaluation
Children with presumptive TB were evaluated using sputum or stool samples.
Between January 2022 and December 2023, 35,636 children were screened. Of these,
- When comparing the diagnosed TB cases between children and adults, the presumptive yield and testing rate were similar.
- In contrast, the adult population had a much higher TB positivity rate with clinical diagnosis.
- The PDX with CAD4TB presents a valuable opportunity for diagnosing TB in children.
- There is a need to validate the performance of CAD systems in children for effective TB detection.
