UNLABELLED Tuberculosis is one of the most important infectious diseases in the world. Only 68% of the estimated new tuberculosis (TB) cases in Brazil are diagnosed. Our aim was to determine the risk of infection among household contacts. STUDY DESIGN Cohort of tuberculin-negative household contacts followed for 12 months. METHODS Household contacts of randomly selected index acid-fast baci...

INTRODUCTION In Tuscany, Tuberculosis incidence is more than triplicate from 1982 to the beginning of the third millennium. The impact of this trend on open population is not known, as updated studies on Tuberculosis prevalence are not available. Tuberculin skin test provides the currently most widely used tool for assessing Tuberculosis transmission in a community and the prevalence of infecti...

OBJECTIVE Because of the disparity between the recommendations regarding age and frequency for the realization of tuberculin testing during childhood, a study of tuberculous infection prevalence according to age was made in order to establish at which ages tuberculin testing would be recommendable and to determine if there is a difference in prevalence between vaccinated and non-vaccinated chil...

We have previously reported the results of ten years of systematic tuberculin Qsting of kindergarten and first grade children in Kansas City, Missouri. This report adds seven yeas of testing in different age groups (8th and 9th; and 4th and 5th grades). As reported in the previous study, the prevalence rates and conversion rates to tuberculin are markedly different depending on the frequency at...

BACKGROUND Awareness of bovine tuberculosis (BTB) by cattle owners is of extreme importance to policy makers when considering mitigation. However, to our knowledge, little is known on cattle owners' awareness of BTB in Zambia. Similarly, such knowledge is uncommon within and outside Africa. The current study investigates the epidemiological characteristics of BTB in Zambian cattle in relation t...

AIMS To study the prevalence of tuberculosis infection among children in household contact with adults having pulmonary tuberculosis, and identify the possible risk factors. METHODS Children under the age of 5 years who were in household contact with 200 consecutive adults with pulmonary tuberculosis underwent tuberculin skin testing. Transverse induration of greater than 10 mm was defined as...

BACKGROUND Tuberculosis (TB) remains one of the leading causes of death among infectious diseases worldwide. Despite its low incidence rates in countries of Western Europe and North America, the resurgence of TB in Eastern Europe and the increased immigration from high-incidence countries imply that extreme vigilance is required in order to detect early, treat, and isolate all new cases. In thi...
