Contact tracing of a 15-year-old girl with smear-negative pulmonary tuberculosis in Tehran
AbstractEarly detection of tuberculosis [TB] cases and supervised treatment are vital for control of the disease. To assess TB transmission from a sputum smear-negative pulmonary TB case, the contacts of a 15-year-old Iranian girl diagnosed with smear-negative TB in 2010 were traced. In all, 52 classmates and close friends and 15 school staff were screened by tuberculin skin test and chest X-ray. Those with a positive skin test or abnormal chest X-ray were further evaluated by chest spiral computed tomography [CT] scan and triple gastric washing. All classmates and close friends were Iranian and female. Of the 52 girls, 17 [32%] had latent infection [either positive skin test or abnormal chest X-ray] and 3 [5.7%] had active TB [abnormal CT or positive culture additional to positive skin test or abnormal X-ray]. None of the staff had abnormal findings. Contact tracing should be considered for contacts of all children with symptomatic pulmonary TB, even those who are smear-negative

Ottmani, S.; Zignol, M.; Bencheikh, N.; Laasri, L.; Blanc, L.; Mahjour, J. (2009)We reviewed data collected from 1993 to 2004 as part of the routine activities of the national tuberculosis [TB] control programme [NTP] in Morocco. More than 1 million household TB contacts were identified in approximately 200 000 investigations. On average, 77% of identified contacts were screened every year; overall prevalence was 2.5%. The proportion of TB cases identified in household contacts of registered cases was 5.6%. This was significantly higher in children under 10 years and in patients registered and diagnosed with symptomatic primary ...
Active tuberculosis among Iraqi schoolchildren with positive skin tests and their household contacts Al Kubaisy, W.; Al Dulayme, A.; Hashim, D.S. (2003)In a prospective cohort study in Iraq, schoolchildren with a positive tuberculin skin test during the nationwide survey in 2000 were followed up in 2002 to determine prevalence of latent tuberculosis [TB] infection and risk factors among household contacts. Of 205 children, 191 remained skin-test positive in 2002. Based on X-ray and clinical examination, 9 children [4.4%] were active TB cases. Among 834 household contacts, there were 144 new TB cases, giving a cumulative incidence of 17.3%. Risk factors for TB among household contacts were: age ...
