Summary
Tuberculin sensitivity was investigated in 1,405 Lebanese school children. A 4.3% prevalence of tuberculosis infection was found, with higher rates in lower socio-economic groups and older children.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Context:
- Tuberculosis (TB) poses a significant global health challenge, particularly impacting vulnerable populations.
- North Lebanon faces a substantial burden of childhood disease attributed to TB.
- This study focuses on a deprived suburb of Tripoli, Lebanon, to assess TB infection markers.
Purpose:
- To determine the prevalence of tuberculin sensitivity in school children in North Lebanon.
- To analyze the relationship between socio-economic status, age, sex, and tuberculin sensitivity.
- To evaluate the clinical status of children with positive tuberculin reactions.
Summary:
- A cross-sectional study assessed tuberculin sensitivity using the Intra-Dermal Reaction (IDR) technique in 1,405 BCG-unvaccinated school children (ages 2-15).
- The overall prevalence of tuberculin sensitivity was 4.3%, significantly higher in the lowest socio-economic group (5.7%) compared to the middle group (2.4%).
- Prevalence increased with age (over 10 years), and induration diameters exceeded 10 mm in 83.6% of positive cases. Chest X-rays and sputum tests for Acid Fast Bacilli (AFB) were negative in all children with positive reactions.
Impact:
- Highlights the significant prevalence of tuberculosis infection in school-aged children in a deprived area of North Lebanon.
- Identifies socio-economic status and age as key factors associated with higher tuberculin sensitivity.
- Suggests the need for targeted public health interventions and further investigation into latent tuberculosis infection in this population.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
