Training of front-line health workers for tuberculosis control: Lessons from Nigeria and Kyrgyzstan

Efficient human resources development is vital for facilitating tuberculosis control in developing countries, and appropriate training of front-line staff is an important component of this process. Africa and Central Asia are over-represented in global tuberculosis statistics. Although the African region contributes only about 11% of the world population, it accounts for at least 25% of annual TB notifications, a proportion that continues to increase due to poor case management and the adverse impact of HIV/AIDS. Central Asia's estimated current average tuberculosis prevalence rate of 240/100 000 is significantly higher than the global average of 217/100 000. With increased resources currently becoming available for countries in Africa and Central Asia to improve tuberculosis control, it is important to highlight context-specific training benchmarks, and propose how human resources deficiencies may be addressed, in part, through efficient (re)training of frontline tuberculosis workers. This article compares the quality, quantity and distribution of tuberculosis physicians, laboratory staff, community health workers and nurses in Nigeria and Kyrgyzstan, and highlights implications for (re)training tuberculosis workers in developing countries

Factors influencing the higher incidence of tuberculosis among migrants and ethnic minorities in the UK.

Migrants and ethnic minorities in the UK have higher rates of tuberculosis (TB) compared with the general population. Historically, much of the disparity in incidence between UK-born and migrant populations has been attributed to differential pathogen exposure, due to migration from high-incidence regions and the transnational connections maintained with TB endemic countries of birth or ethnic origin. However, focusing solely on exposure fails to address the relatively high rates of progression to active disease observed in some populations of latently infected individuals. A range of factors that disproportionately affect migrants and ethnic minorities, including genetic susceptibility, vitamin D deficiency and co-morbidities such as diabetes mellitus and HIV, also increase vulnerability to infection with Mycobacterium tuberculosis (M.tb) or reactivation of latent infection. Furthermore, ethnic socio-economic disparities and the experience of migration itself may contribute to differences in TB incidence, as well as cultural and structural barriers to accessing healthcare. In this review, we discuss both biological and anthropological influences relating to risk of pathogen exposure, vulnerability to infection or development of active disease, and access to treatment for migrant and ethnic minorities in the UK
