Area of Science:
- Public Health
- Infectious Disease Control
- Pediatric Health
Background:
- India's Revised National Tuberculosis Control Programme (RNTCP) mandates tuberculosis (TB) screening for household contacts of smear-positive pulmonary TB (PTB) cases.
- The RNTCP also recommends 6-month isoniazid preventive therapy (IPT) for asymptomatic children under 6 years old.
Purpose of the Study:
- To evaluate the effectiveness of child contact screening and IPT administration within the RNTCP framework.
- Assessing the implementation gaps in child tuberculosis prevention strategies.
Main Methods:
- A cross-sectional study was conducted in urban and rural areas of Tamil Nadu, South India.
- Data collection involved reviewing TB treatment cards, interviewing TB patients, and conducting focus group discussions with healthcare workers.
Main Results:
- Only 14% of child contacts (<14 years) were screened for TB, and 19% of eligible children (<6 years) received IPT.
- Incomplete documentation of contact details on treatment cards was observed.
- Healthcare workers showed varying levels of TB awareness and procedural knowledge.
Conclusions:
- Improved implementation of contact screening and IPT requires better documentation systems, such as dedicated IPT cards.
- Targeted training for healthcare workers is crucial to enhance knowledge and adherence to TB control protocols.
Background:
India's Revised National Tuberculosis Control Programme (RNTCP) recommends screening of all household contacts of smear-positive pulmonary tuberculosis (PTB) cases for tuberculosis (TB) disease, and 6-month isoniazid preventive therapy (IPT) for asymptomatic children aged <6 years.
Objective:
To assess the implementation of child contact screening and IPT administration under the RNTCP.
Methods:
A cross-sectional study conducted in four randomly selected TB units (TUs), two in an urban (Chennai City) and two in a rural (Vellore District) area of Tamil Nadu, South India, from July to September 2008. The study involved the perusal of TB treatment cards of source cases (new or retreatment smear-positive PTB patients started on treatment), interview of source cases and focus group discussions (FGDs) among health care workers.
Results:
Interviews of 253 PTB patients revealed that of 220 contacts aged <14 years, only 31 (14%) had been screened for TB, and that of 84 household children aged <6 years, only 16 (19%) had been initiated on IPT. The treatment cards of source cases lacked documentation of contact details. FGDs revealed greater TB awareness among urban health care workers, but a lack of detailed knowledge about procedures.
Conclusion:
Provision for documentation using a separate IPT card and focused training may help improve the implementation of contact screening and IPT.

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.
