[Results of tuberculosis screening in children with household contact].
BACKGROUND
Tuberculosis screening in children is important to identify and treat latent tuberculosis infection and thus avoid progression to disease.


METHODS
It is a prospective study realized in 83 children between November 2009 and January 2013 who consulted after a household contact for tuberculosis in the pediatric department B of Abderrahmen Mami hospital of Ariana.


RESULTS
The mean age of the children was 4.8 years (3 months-15 years). A latent tuberculosis infection was diagnosed in 31.3% of children, 10.8% had tuberculosis and 57.8% were considered healthy. Fifty-seven children (68.7%) had a close daytime contact with the index and 57.8% slept in the same bedroom of the contaminator. The identified risk factors were the diagnosis delay of the index of more than 30 days (P=0.023), presence of cavitations on the chest X-ray of the index (P=0.029) and a close daytime contact (P=0.004).


CONCLUSIONS
Our study showed a high rate of contamination in children with a household contact. Efforts are needed to shorten the time to diagnosis of adults' tuberculosis.
