Background: The persistence of tuberculosis today and its global disparity send a powerful message that effective tuberculosis control must respond to its regional epidemiology. Active case finding through contact investigation is a standard protocol used for tuberculosis control, but its effectiveness has not been established, especially in endemic areas.
Methods: To quantify the potential effectiveness of contact investigation in Kampala, Uganda, we used a cross-sectional design to evaluate the social networks of 123 tuberculosis index cases and 124 controls without tuberculosis.

Aflatoxins are naturally occurring food toxins known to contaminate cereals with a carry-over effect in milk and meat products from farm animals raised on contaminated feed. In children, continuous consumption of aflatoxin-contaminated food is linked to immune suppression, vaccine interference and growth faltering while in adult populations, carcinogenesis in the liver has been established. We evaluate the main determinants of aflatoxin exposures among children recruited from primary schools in Makueni and Siaya Counties.

The aim of this study was to estimate excess risk of M. tuberculosis infection among household and extra-household contacts of index cases.

Aflatoxin exposure, malnutrition and growth impairment in children present significant public health problems in low- and middle-income countries. Recent epidemiology studies show that exposure to aflatoxins through dietary sources in early life contributes to growth retardation among children. However, the findings remain inconclusive due to limited comparative studies in high versus low aflatoxin exposure regions.

Introduction: In Vietnam, Alzheimer's disease (AD) and other dementias have become an increasingly important public health problem among the elderly. Achieving a diagnosis tool with high reliability and validity is essential. The Clinical Dementia Rating (CDR) is a global clinical scale with established diagnostic and severity-ranking utility that has been widely employed in epidemiological studies in an international context.

The efficacy and effectiveness of the influenza vaccine are a key determinant of vaccine uptake. This review aimed to synthesize the available evidence on the protection of both seasonal and monovalent pandemic H1N1 (pdmH1N1) vaccine against laboratory-confirmed influenza (LCI), influenza-like illness (ILI), and respiratory illness (RI).
