Since 1995, WHO has ensured a consistent approach to national, regional and global TB surveillance by providing standardized definitions, forms and registers for the recording and reporting of individual-level and aggregated data about people diagnosed with and treated for TB, which are used worldwi...de. This standardization has facilitated the regular reporting of TB data to WHO from 215 countries and areas in annual rounds of global TB data collection, with findings published in an annual WHO global TB report since 1997 and data made publicly available via the online WHO global TB database.

Le cadre de surveillance basé sur les événements est destiné à être utilisé par les autorités et les
agences responsables de la surveillance et de l'intervention. Ce cadre sert de cadre pour guider les
parties prenantes intéressées par la mise en œuvre de la surveillance basée sur le...s événements (SBÈ)
en utilisant une approche multisectorielle axée sur l'approche « Une seule santé ». À cette fin, le
document est organisé en chapitres et annexes interconnectés qui peuvent être modifiés et adaptés,
selon les besoins, par les utilisateurs.
Il s'agit d'une version révisée du « Cadre pour la surveillance basée sur les événements » original qui
a été publié en 2018. Ce cadre ne remplace aucun autre matériel SBÈ disponible, mais s'appuie plutôt
sur des documents pertinents ou connexes existants et sert de guide pratique pour la mise en œuvre
de l'SBÈ en Afrique. Ce cadre est conforme à la troisième édition de l'évaluation externe conjointe de
l'OMS pour les indicateurs suivants : systèmes d'alerte précoce renforcés capables de détecter les
événements importants pour la santé publique et la sécurité sanitaire (indicateur D2.1) ; amélioration
de la communication et de la collaboration entre les secteurs et entre les niveaux d'autorité nationaux,
intermédiaires et locaux d'intervention en matière de santé publique en matière de surveillance des
événements importants pour la santé publique (indicateur D2.2) ; et amélioration de la capacité
d'analyse des données aux niveaux national et intermédiaire ( Indicateur D2.3). Au fur et à mesure
que les pays commenceront à mettre en œuvre et à démontrer la fonctionnalité SBÈ, ils garantiront
une augmentation des scores EEC et des progrès vers le respect des exigences décrites dans l'RSI
(Règlement sanitaire international).
En outre, dans les États membres de l'Union africaine qui ont adopté la Surveillance et réponse
intégrées aux maladies (SRIM), ce document complète et peut améliorer la mise en œuvre de l'SRIM,
en particulier pour la 3e édition (2019) qui inclut des composants liés à l'SBÈ.

The WHO Global Antimicrobial Resistance and Use Surveillance System (GLASS) was launched in 2015 to foster AMR surveillance and inform strategies to contain AMR. The system started with surveillance of AMR in bacteria causing common human infections and has expanded its scope to include surveillance... of antimicrobial consumption (AMC), invasive fungal infections, and a One Health surveillance model relevant to human health. To meet future challenges, it is in continuous evolution to enhance the quality and representativeness of data to inform the AMR burden accurately. As of the end of 2022, 127 countries, territories and areas participate in GLASS.
The fifth GLASS report, produced in collaboration with Member States, summarizes 2020 data on AMR rates in common bacteria from countries, territories, and areas. The report brings new features, including analyses of population testing coverage or AMR trends. For the first time, the report presents 2020 data on AMC at the national level. A new interactive dashboard allow users to explore AMR and AMC global data, country profiles and download the data.
This report marks the end of the early implementation phase of GLASS. In addition to presenting data collected through the latest data call, this report provides a summary of five years of national AMR surveillance data contributed to GLASS from its initiation, presents AMR findings in the context of progress of country participation in GLASS and in global AMR surveillance coverage and laboratory quality assurance systems at (sub)national level.
Patterns of antimicrobial consumption are presented by country with a particular focus on antibacterials. The report also presents the antimicrobial consumption according to the WHO AWaRe antibiotic classification, for penicillins and cephalosporines. From a One Health perspective, the report presents antimicrobial consumption data in the human sector expressed in tons to allow a comparison with antimicrobial consumption from other sectors (not included in this report).

Africa CDC Institute of Pathogen Genomics (IPG) was launched in November 2019 and operates under the Division of Laboratory Systems and Networks.
IPG coordinate the implementation of molecular diagnostics, pathogen genomics and bioinformatics in National Public Health Institutions (NPHIs) and/or Re...fe-
-rence Laboratories (NRLs) across Africa.
Africa CDC and APHF are coordinating a continental initiative to maximize the benefits of molecular approaches and pathogen genomics for more effective
outbreak preparedness, prevention, response, and for the control and elimination of endemic diseases in Africa. One of Africa CDC’s flagship initiative is the Africa
Pathogen Genomics Initiative (Africa PGI), a partnership that aims to strengthen laboratory systems and enhance genomic surveillance by equipping the continent’s
public health institutions with the tools, training, and data infrastructure.
About the Project
In 2023, 166 outbreaks and public health events were reported in Africa. This calls for a resilient laboratory systems for timely detection and reporting of current and future outbreaks. This project aims to scale up molecular diagnostic and genomic sequencing-based detection and characterization of outbreaks.
Africa CDC is working with Member States to develop guidance, diagnostic algorithm, training and capacity building to enable outbreak detection, and reporting to inform public health response.

DHS Further Analysis Reports No. 107 - This report, based largely on the 2014-15 national survey in Rwanda, focuses on changes and trends in reproductive behavior since 2010. In the 4-5 years after the 2010 survey, fertility continued its decline to 4.2 births per woman as contraceptive prevalence i...ncreased slightly. However, the earlier downward trend in number of children desired appears stalled. This is clearly evident from an increase in the proportions of married women and men who say they want more children. Child mortality has significantly declined and remains strongly related to fertility; while age at marriage has continued to increase. The demographic goals specified in the 1998-99 plan for development, Rwanda Vision 2020, appear on track, but the annual rate of population growth remains high, currently 2.5%, because fertility is high. Furthermore, large numbers of young people are now entering their child-bearing years. Although most trends seem encouraging, especially compared with other countries in sub-Saharan Africa, significant population growth is expected in Rwanda, from 12 to 16 million people by 2030, and to 22 million people by mid-century, even with assumed reductions of fertility.

The ongoing COVID-19 pandemic presents an exceptional and unprecedented challenge for competent authoritiesa with responsibilities for national food safety control systemsb to continue conducting routine functions and activities in accordance with national regulations... and international recommendations. In many countries, competent authority staff are largely working from home, teleworking being the normal practice, and all face-to-face meetings cancelled or rescheduled as teleconferences. It is challenging to maintain, without interruption, routine activities such as the inspection of food business operations, certifying exports, control of imported foods, monitoring and surveillance of the safety of the food supply chain, sampling and analysis of food, managing food incidents, providing advice on food safety and food regulations for the food industry, and communicating on food safety issues with the public.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.

Antimicrobial resistance (AMR) is a global human, animal, plant and environment health threat that needs to be addressed by every country. The impacts of AMR are wide-ranging in terms of human health, animal health, food security and safety, environmental effects on ecosystems and biodiversity, and ...socioeconomic development. Just like the climate crisis, AMR poses a significant threat to the delivery of the 2030 Agenda for Sustainable Development. The response to the AMR crisis has been spearheaded through the global action plan on antimicrobial resistance (GAP-AMR), developed by the World Health Organization (WHO) in 2015, in close collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (WOAH), and formally endorsed by the three organizations’ governing bodies and by the Political Declaration of the high-level meeting of the United Nations General Assembly on AMR in 2016. In 2022, the three organizations officially became the Quadripartite by welcoming the United Nations Environment Programme (UNEP) into the alliance “to accelerate coordination strategy on human, animal and ecosystem health”.
The aim of the GAP-AMR is to ensure the continuity of successful treatment with effective and safe medicines.
Its strategic objectives include:
• improving the awareness and understanding of AMR;
• strengthening the knowledge and evidence base through surveillance and research;
• reducing the incidence of infection through effective sanitation, hygiene and infection prevention measures; optimizing the use of antimicrobial medicines in human and animal health; and
• developing the economic case for sustainable investment that takes account of the needs of all countries and increasing investment in new medicines, diagnostic tools, vaccines and other interventions.
With the adoption of the GAP-AMR, countries agreed to develop national action plans (NAPs) aligned with the GAP-AMR to mainstream AMR interventions nationally. Individually, the Quadripartite took action to advance AMR interventions in their respective sectors. FAO adopted a resolution on AMR recognizing that it poses an increasingly serious threat to public health and sustainable food production, and developed an AMR action plan to support the resolution’s implementation. For its part, WOAH developed a strategy on AMR aligned with the GAP-AMR, acknowledging the importance of a One Health approach to AMR. Similarly, more recently, UNEP’s governing body, the United Nations Environment Assembly, recognized that AMR is a current and increasing threat and a challenge to global health, food security and the sustainable development of all countries, and welcomed the GAP-AMR and the NAPs developed in accordance with its five overarching strategic objectives

Since 2001, several Demographic and Health Surveys (DHS) include HIV
testing. For many countries, in particular in sub-Saharan Africa, DHS are
the only national source of data in general population. Several DHS collect
latitude and longitude of surveyed clusters but the sampling method is not
ap...propriate to derive local estimates: sample size is not large enough for a
direct spatial interpolation.
We developed a generic approach to map spatial regional trends of HIV
prevalence from DHS. We present how our results from Burkina Faso 2003
DHS shed new light on HIV epidemics.

The Democratic Republic of Timor-Leste has the highest TB incidence rate in the South East Asian Region - 498 per 100,000, which is the seventh highest in the world. In Timor-Leste TB is the eighth most common cause of death.
The salient observations are as follows:
In 2018, 487 (12.5%) of the... 3906 notified TB patients were tested for RR-TB and only 12 lab confirmed RR-TB patients were initiated on standard MDR-TB treatment of 20-months duration, (a 3-fold increase in RR-TB detection compared with 2017). This amounts to treatment coverage of only 17% of 72 estimated MDR/RR-TB among notified TB patients (3906) and 5% of 240 estimated incident MDR-TB patients as compared to 62% treatment coverage of 6300 incident drug sensitive TB patients estimated in TLS. The treatment success in the 2016 annual cohort of 6 MDR-TB patients has been reported at 83%. 80% of TB patients know their HIV Status with around 1% TB-HIV co-infection, 37/ 77 (48%) TB-HIV Co-infection Detected. Of the 387 PLHIV currently alive on ART, exact status on TB screening and testing is unknown. % of PLHIV newly enrolled in HIV care who received IPT is not known.
In 2018, the mortality rate for TB was 94 deaths per 100,000 people (1200 per annum) in TL with an increasing mortality trend (Figure 1), despite TB services being available for nearly two decades.
A survey of catastrophic costs due to TB (2016) highlights that 83% of TB patients are reported to be facing catastrophic costs due to the disease. This is the highest rate in the world.

Effective monitoring, epidemiological assessment and evaluation are necessary to achieve the aim of interrupting LF transmission. This manual is designed to ensure that national elimination programmes have available the best information on methodologies and procedures for monitoring MDA, appropriate...ly assessing when infection has been reduced to levels where transmission is likely no longer sustainable, implementing adequate surveillance after MDA has ceased to determine whether recrudescence has occurred, and preparing for verification of the absence of transmission. The manual provides general guidance to national programmes; relevant background information on technical issues is contained in the annexes. As real-life situations may not correspond to predefined categories, consultation with WHO and experts is recommended in complicated situations.

Rabies is a fatal viral disease, but is preventable in humans. The rabies virus is transmitted to humans through virus-laden saliva from a rabid animal, mostly dogs. The virus is shed in the saliva of an infected animal and can be introduced into another body through bites, scratches and any other ...wounds that transect the skin. Contact of the infected saliva with mucous membranes is also thought to be a possible route of infection, whereas contact of infected saliva with intact skin is not considered an exposure. Rabies is preventable through pre-exposure prophylaxis (PrEP) for individuals at high and continual risk, and post-exposure prophylaxis (PEP).
