We conducted a cross-sectional study from August 2003 to February 2004 to identify risk factors for bovine tuberculosis (BTB) in the Kafue basin of Zambia. We investigated a total of 106 herds of cattle for presence of BTB using the comparative intradermal tuberculin test (CITT) while an interviewer-administered questionnaire was used to gather epidemiological data on herd structure, management...

The recent epidemiology of TB and data on risk factors for LTBI are reviewed. The evidence-based recommendations provided emphasize the paradigm that children and adolescents should be screened for risk factors by using a risk-factor question...
