Insights
Childhood tuberculosis (TB) is a significant public health issue in Seine-Saint-Denis. Effective contact tracing identified most pediatric TB cases, highlighting the need for broader notification criteria.
Area of Science:
- Public Health
- Pediatrics
- Infectious Diseases
Background:
- Paediatric tuberculosis (TB) reporting has been limited in recent decades.
- Seine-Saint-Denis, a low-income Paris suburb, faces a notable burden of childhood TB.
Purpose of the Study:
- To investigate diagnostic and treatment practices for children with TB in Seine-Saint-Denis.
- To assess the effectiveness of current TB surveillance and notification methods in a pediatric population.
Main Methods:
- A retrospective study identified pediatric TB cases (under 15 years) treated between September 1996 and December 1997.
- Questionnaires were distributed to hospitals and prevention units serving the area to collect data on TB diagnosis and treatment.
Main Results:
- Ninety-two pediatric TB cases were identified, with 65% diagnosed through contact tracing.
- Latent TB infection accounted for 50% of treatments, and 40% of affected children were under five years old.
- Current mandatory notification criteria in France were found to be too restrictive, with only 15 of 35 notified cases meeting the requirements.
Conclusions:
- Tuberculosis remains a public health concern in Seine-Saint-Denis, particularly among children.
- The high rate of case identification via contact tracing underscores the program's success.
- Revisions to mandatory notification criteria since 2002, including tuberculous infection, aim to improve childhood TB surveillance.
Setting:
Few series of paediatric tuberculosis (TB) have been reported in the last 20 years.
Objective:
To describe diagnostic and treatment practices in children with TB living in Seine-Saint-Denis, a low-income Paris suburb.
Methods:
Local TB incidence in 1998 was 34.2/100,000 overall and 10.2/100,000 in children. Between September 1996 and December 1997, the hospitals and prevention units serving the area's paediatric population were sent questionnaires to identify TB cases in children aged under 15 living in Seine-Saint-Denis and treated with at least one anti-tuberculosis drug.
Results:
Of 92 cases identified, 60 (65%) had been diagnosed during contact tracing; for 52 patients (60%), the index case had been found. The reason for anti-tuberculosis treatment was active TB in 26 (28.3%), latent TB in 46 (50%), and prophylaxis in 20 (21.8%). Forty per cent (37/92) of the patients were aged under 5. Only 15 of the 35 notified cases met the criteria for mandatory notification (at least three anti-tuberculosis drugs).
Conclusion:
TB remains a public health problem in Seine-Saint-Denis. The high proportion of cases identified by contact tracing attests to the efficacy of the local contact-tracing programme. The criteria for mandatory notification in France were too restrictive to ensure effective surveillance of childhood TB. Since 2002, notification has included cases of tuberculous infection in children.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
