National tuberculosis (TB) prevalence surveys provide a nationally representative measurement of the burden of TB disease in the population, at a given point in time. Repeat surveys allow assessment of trends and tracking of progress towards national and global targets for reductions in TB disease b...urden. Survey data also provide important insights that can help national TB programmes to identify ways to improve TB diagnosis and treatment.
National TB prevalence surveys are relevant in countries that do not yet have national disease notification and vital registration systems that are of sufficiently high quality and coverage to allow reliable tracking of TB disease burden.

O volume de capacitação em Bases do diagnóstico microscópico da malária é composto por dois módulos, que servem como uma estrutura para que os instrutores montem o curso. Ele fornece as informações mínimas necessárias para capacitar alunos em diagnóstico microscópico da malária pelo m...todo de Giemsa. O volume destina-se principalmente a pessoas com escolaridade relativamente baixa no momento do início do curso; os instrutores podem ajustar o curso para participantes com níveis mais altos de escolaridade. Técnicos atualmente responsáveis pelo diagnóstico microscópico da malária também se beneficiarão da leitura do Guia do aluno.

The bench aids are intended for use as both a practical tool for health workers engaged in the routine diagnosis of malaria infections
En la reunión de alto nivel de las Naciones Unidas del 2018 se fijó el objetivo de tratar al menos a 40 millones de personas con tuberculosis (TB) entre el 2018 y el 2022; sin embargo, en el 2021 ese objetivo solo se había cumplido en un 66%. Las pruebas diagnósticas son fundamentales para logra...r el objetivo, pero constituyen un eslabón débil en la continuidad de la atención. Las pruebas de diagnóstico rápido recomendadas por la Organización Mundial de la Salud (PDRO) son sumamente precisas, acortan el tiempo hasta el inicio del tratamiento, influyen en resultados importantes para el paciente y son costo-eficaces. Aunque el objetivo para el año 2025 es que todos los pacientes notificados se hagan inicialmente una PDRO, en el 2021 tan solo el 38% se hizo una PDRO como prueba inicial, y se determinó que el acceso a las pruebas diagnósticas era un problema crítico. Una de las principales consecuencias del uso insuficiente de las PDRO es la gran brecha en la detección de la farmacorresistencia. La presente Norma de la OMS: Acceso universal a las pruebas de diagnóstico rápido de la tuberculosis se basa en las directrices de la OMS y en el manual operativo conexo
