Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Ebola disease and Marburg disease outbreaks continue to occur in Africa, with increased frequency. In addition to resulting in high mortality and morbidity, the outbreaks generate fear and mistrust about the response activities within the communities affected.
Infection prevention and control (IP...C) is a key pillar in the outbreak response; adherence to IPC practices can prevent and control transmission of infections to health and care workers, patients and their family members.
During the 2014-2016 West African Ebola disease outbreak, there was an urgent need for rapid IPC guidance to help support ministries of health, health-care providers and non-governmental organizations (NGOs). In response, WHO produced several documents related to the outbreak based on expert opinion, including IPC-specific documents and documents on clinical management that also referenced key IPC principles and practices. Since that time, many practices in the field have become institutionalized.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular diseases, diabetes and chronic respiratory diseases and their risk factors are an increasing public health and development challenge in Turkey. This report provides evidence through three analyses that NCDs reduce economic output, and di...scusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs are equivalent to 3.6% of gross domestic product. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

An economic burden analysis shows that economic losses from NCDs are equivalent to 3.9% of gross domestic product.

A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment.

The Pharmaceutical Forum of the Americas (PFA) has previously published guidelines and organised campaigns for community pharmacists on the prevention, detection and control of arbovirus infections in 2018 with a grant from the FIP Foundation for Pharmacy Education and Research. Building on that exp...ertise, FIP joined efforts with the PFA and is now publishing its first-ever handbook to support pharmacists in the
area of vector-borne diseases. As the integration of the regional forums in FIP advances, such collaborative projects are tangible results of an increasingly regionally informed and regionally targeted work by FIP.

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.
