The Event-based Surveillance Framework is intended to be used by authorities and agencies responsible for
surveillance and response. This framework serves as an outline to guide stakeholders interested in implementing
event-based surveillance (EBS) using a multisectoral, One Health approach. To ...that end, the document is arranged
in interlinked chapters and annexes that can be modified and adapted, as needed, by users.
This is a revised version of the original “Framework for Event-based Surveillance” that was published in 2018. This
framework does not replace any other available EBS materials, but rather builds on existing relevant or related
documents and serves as a practical guide for the implementation of EBS in Africa. This framework is aligned with
the third edition of the WHO Joint External Evaluation for the following indicators: strengthened early warning
surveillance systems that are able to detect events of significance for public health and health security (Indicator
D2.1); improved communication and collaboration across sectors and between National, intermediate and local
public health response levels of authority regarding surveillance of events of public health significance (Indicator
D2.2); and improved national and intermediate-level capacity to analyse data (Indicator D2.3). As countries begin
to implement and demonstrate EBS functionality they will ensure an increase in JEE scores and progress towards
meeting the requirements outlined in the IHR3F
Additionally, in African Union Member States that have adopted the Integrated Disease Surveillance and
Response (IDSR) strategy, this document is a complement to and can enhance the implementation of IDSR,
especially for the 3rd edition (2019) that includes components related to EBS.

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.

Malgré les progrès récents vers la mise au point d’un traitement hautement efficace et abordable contre le virus de l’hépatite C, beaucoup de personnes infectées par ce virus ne connaissent pas leur statut. L’Organisation mondiale de la Santé (OMS) estime qu’en 2019, 58 millions ...de personnes à travers le monde étaient atteintes d’une infection chronique par le virus de l’hépatite C, et qu’à peine 21 % d’entre elles avaient été diagnostiquées. Le défaut de sensibilisation, l’accès limité aux services de dépistage et de traitement, la stigmatisation, la discrimination et d’autres obstacles structurels contribuent au faible taux d’utilisation des services de dépistage du virus de l’hépatite C.

There is an expanding market of no- and low-alcohol beverages (NoLos). However, their effects on global ethanol consumption and public health are still questioned. Policies and regulations about NoLos’ availability, acceptability and affordability are lacking and evidence about their benefits is l...imited. Concerns have been raised about the impact of NoLos in reducing alcohol consumption and its associated harm and the possible drawbacks and implications, such as misleading minors, pregnant women, abstainers or those seeking to stop drinking about their actual ethanol content. Further, there are concerns about the implications of NoLo branded products being displayed close to the brand’s main alcoholic beverages and their potential to subtly lead to new occasions of drinking. There is a need to monitor their consumption and impact on aggregated alcohol consumption to understand the public health implications of NoLos. The alcohol by volume content of NoLos must be defined, harmonised and clearly labelled. NoLo marketing needs to be regulated to protect children, pregnant women and those seeking to stop drinking. Fiscal and pricing policies to reduce the affordability of products with higher strengths of ethanol may favour a shift towards lower alcohol strength beverages.

There has been important progress for the rights of adolescent girls and women in recent decades, yet millions still struggle to
access the nutritious diets, essential nutrition services and nutrition and care practices they need to prevent malnutrition.
Undernutrition, micronutrient deficiencies ...and anaemia amplify gender inequalities by lowering learning potential, wages and life opportunities for adolescent girls and women, weakening their immunity to infections, and increasing their risk of lifethreatening complications during pregnancy and childbirth.

This paper introduces a new dataset of official financing—including foreign aid and other forms of concessional and non-concessional state financing—from China to 138 countries between 2000 and 2014. We use these data to investigate whether and to what extent Chinese aid affects economic growth ...in recipient countries. To account for the endogeneity of aid, we employ an instrumental-variables strategy that relies on exogenous variation in the supply of Chinese aid over time resulting from changes in Chinese steel production. Variation across recipient countries results from a country’s probability of receiving aid. Controlling for year- and recipient-fixed effects that capture the levels of these variables, their interaction provides a powerful and excludable instrument. Our results show that Chinese official development assistance (ODA) boosts economic growth in recipient countries. For the average recipient country, we estimate that one additional Chinese ODA project produces a 0.7 percentage point increase in economic growth two years after the project is committed. We also benchmark the effectiveness of Chinese aid vis-á-vis the World Bank, the United States, and all members of the OECD’s Development Assistance Committee (DAC).

I examine the effectiveness of donors in targeting the highest burden of malaria in the Democratic Republic of Congo when health information structure is fragmented. I exploit local variations in the burden of malaria induced by mining activities as well as financial and epidemiological data from he...alth facilities to estimate how local aid is matching local health needs. Using a regression discontinuity design, I find significant but quantitatively small variations in aid to health facilities located within mining areas. Comparing local aid with the additional cost of treatment and prevention associated with the increased risk of malaria transmission, I find suggestive evidence that local populations with the highest burden of the disease receive a proportionately lower share of aid compared to neighbouring areas with reduced exposure to malaria infection. The evidence of disparities in the allocation of aid for malaria supports the view that donors may have inaccurate information about local population needs.

In October 2022, President Biden signed the Global Malnutrition Prevention and Treatment Act (GMPTA) into law, which directs USAID to prevent and treat malnutrition globally. The GMPTA further codifies USAID’s leadership on nutrition, with a focus on evidence-based interventions across health syst...ems and food systems, in both development and humanitarian settings.
Realizing the potential of good nutrition to save lives and ensure a brighter future for generations to come is central to U.S. Government priorities. For over 60 years, USAID has been a leader in the fight to end global malnutrition. Nutrition affects every aspect of human development: from the ability to fight disease, to children’s performance in school, to a nation’s health and economic advancement. There is overwhelming evidence of the power of good nutrition but, due to challenges in accessing safe, nutritious foods and health and sanitation services, many people in low- and middle-income countries remain undernourished.

Hypertension is referred to as a “silent killer”. Most people with hypertension are unaware of their condition as in most cases, they experience no warning signs or symptoms hence they are not identified or treated. Hypertention is associated with a number of conditions, disability, and causes o...f death. These include: strokes; myocardial infarction; end-stage renal disease; congestive heart failure; peripheral vascular disease and blindness. According to Stats SA, in 2017, hypertensive disorders resulted in 19 900 deaths with a further 44 357 deaths associated with cerebrovascular diseases and other heart diseases. This means around 30% of all deaths in 2017 were associated with increased blood pressure.

Background
Cardiovascular diseases (CVDs) are one of the global leading causes of concern due to the rising prevalence and consequence of mortality and disability with a heavy economic burden. The objective of the current study was to analyze the trend in CVD incidence, mortality, and mortality-to-...incidence ratio (MIR) across the world over 28 years.
Methods
The age-standardized CVD mortality and incidence rates were retrieved from the Global Burden of Disease (GBD) Study 2017 for both genders and different world super regions with available data every year during the period 1990–2017. Additionally, the Human Development Index was sourced from the United Nations Development Programme (UNDP) database for all countries at the same time interval. The marginal modeling approach was implemented to evaluate the mean trend of CVD incidence, mortality, and MIR for 195 countries and separately for developing and developed countries and also clarify the relationship between the indices and Human Development Index (HDI) from 1990 to 2017.
Results
The obtained estimates identified that the global mean trend of CVD incidence had an ascending trend until 1996 followed by a descending trend after this year. Nearly all of the countries experienced a significant declining mortality trend from 1990 to 2017. Likewise, the global mean MIR rate had a significant trivial decrement trend with a gentle slope of 0.004 over the time interval. As such, the reduction in incidence and mortality rates for developed countries was significantly faster than developing counterparts in the period 1990–2017 (p < 0.05). Nevertheless, the developing nations had a more rather shallow decrease in MIR compared to developed ones.
Conclusions
Generally, the findings of this study revealed that there was an overall downward trend in CVD incidence and mortality rates, while the survival rate of CVD patients was rather stable. These results send a satisfactory message that global effort for controlling the CVD burden was quite successful. Nonetheless, there is an urgent need for more efforts to improve the survival rate of patients and lower the burden of this disease in some areas with an increasing trend of either incidence or mortality.

Global cardiovascular disease (CVD) burden is high and rising, especially in low-income and middle-income countries (LMICs). Focussing on 45 LMICs, we aimed to determine (1) the adult population’s median 10-year predicted CVD risk, including its variation within countries by socio-demographic char...acteristics, and (2) the prevalence of self-reported blood pressure (BP) medication use among those with and without an indication for such medication as per World Health Organization (WHO) guidelines.
