Un comité OMS d’experts sur la trypanosomiase humaine africaine (THA) : lutte et surveillance, s’est réuni à Genève (Suisse), du 22 au 26 avril 2013. Le Dr H. Nakatani, sous-directeur général pour le VIH/SIDA, la tuberculose, le paludisme et les maladies tropicales négligées, a ouvert la... réunion au nom du Dr M. Chan, directeur-général de l’OMS.
La THA est une maladie qui afflige les populations rurales de l’Afrique, là où prolifère la mouche tsé-tsé (ou glossine), vecteur des trypanosomes qui en sont la cause. On distingue deux formes de THA : la forme à T. b. gambiense ou forme gambienne, endémique en Afrique de l’Ouest et en Afrique centrale et qui
représente actuellement 95 % des cas, et la forme à T. b. rhodesiense ou forme rhodésienne, endémique en Afrique de l’Est et en Afrique australe, à laquelle sont dus les 5 % restants.

Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

Esta publicación integra la experiencia acumulada de la OPS y las buenas prácticas desarrolladas por sus Estados Miembros en los últimos años, incluidas las discusiones y experiencias compartidas en las reuniones regionales celebradas sobre el tema, y pone el acento en la innovación y la inclus...ión social. Esto requiere cambiar con urgencia los paradigmas tradicionales, partiendo de las acciones específicas que reducen gradualmente la incidencia de la TB para dirigirnos hacia acciones multisectoriales de eficacia demostrada en la contención rápida de la epidemia.

People living with HIV who have a low CD4 count are at a much higher risk of falling ill from TB infection than HIV negative people.
It is important to offer both HIV testing to TB patients and TB diagnosis in HIV patients. Early detection and effective treatment are essential to preventing TB...-associated deaths.
WHO and UNAIDS have strongly advised countries to ensure that HIV programmes integrate regular TB screening, preventive therapy and early treatment.

The SAARC Member States have more than an estimated 2.0 million TB cases accounting for close to one-third of the total cases of TB in the world. India alone had almost one-fifth of the global disease burden due to TB. India, Pakistan and Bangladesh followed by Afghanistan are the major contributors... of disease burden of TB in the SAARC Region. They are countries that have a dubious distinction of being on the list of 22 TB High Disease Countries in the world.

The WHO Global tuberculosis report 2024 provides a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease, at global, regional and country levels. This is done in the context of global TB commitments, strategies and targets.
These guidelines are designed for settings with limited resources to provide inexpensive and effective control strategies for prevention of TB transmission in health care workers (HCW).
About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.
