We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in ...the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges, supporting a cost-effective IVS strategy for early warning of CL outbreaks through an environmental modification alert network, which includes multiple sources of information and actors. In relation to VL, the earliest colonization sites and spatial distribution were explained by modeling and forecasting the most likely hotspots, persistent in time and space, and modulated by environmental variables. Therefore, for VL, a scalar strategy of critical site selection is proposed from a “city” scale based on secondary sources such as remote sensing for the definition of possible areas to monitor and intervene, a scale of restriction from possible to most likely areas through local knowledge, and a “focal site” scale of trap placement through field observation; in this way, IVS activities are carried out at a few sites of the urban landscape and allow a sustainable program.

This research paper uses the Health Resources and services Availability Mapping System (HeRAMS) database to develop two composite indices – one for health centres and one for hospitals – in order to analyse and assess the health facilities’ performance across time and to evaluate the di...sparities among regions in the Syrian Arab Republic. The indices will provide an evidence-based tool for the main actors in the health sector to identify gaps, to intervene accordingly and to assess the impact of their interventions on the health system. The process of constructing the indices includes description and selection of variables, application of normalization techniques and weighting methods, and sensitivity analysis.
A literature review, analysis of the scope of the HeRAMS database, analysis of the crisis situation, data limitation and expert consultations were the main aspects of the construction process of the indices.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.

La Stratégie de riposte face à la résistance aux antipaludiques en Afrique est un document technique de sensibilisation qui se fonde sur les bases factuelles les plus solides dont on dispose et vise à réduire au maximum la menace et l’impact de la résistance aux antipaludiques de Plasmodium ...falciparum en Afrique. Elle a pour objectifs i) d’améliorer la détection de la résistance et d’assurer une riposte en temps utile ; ii) de retarder l’émergence de la résistance à l’artémisinine et aux médicaments associés utilisés dans les combinaisons thérapeutiques à base d’artémisinine (CTA) ; et iii) de freiner la sélection et la propagation des parasites résistants là où une pharmacorésistance est confirmée. Si la Stratégie cible l’Afrique, il convient de noter que la
menace de la résistance aux antipaludiques concerne tous les pays d’endémie palustre et que les interventions proposées dans le présent document sont applicables dans d’autres régions géographiques à condition d’être adaptées aux spécificités locales.

AVADAR is a mobile sms-based software application designed to improve the quality and sensitivity of Acute Flaccid Paralysis (AFP) surveillance by health workers and key informants within hospital facilities and local communities.
The idea is simple: Health workers visit remote villages to check if... local inhabitants have any symptoms of a range of life-threatening infectious diseases, including polio and measles. Then, with the mobile app, they quickly and easily alert WHO.
The AFP video component was developed by World Health Organization (WHO) and eHA, and the software design component was handled by Novel-T. To date, eHA has translated the app into 17 languages.
Informant Selection & Capacity Building
The selection of informants (including health workers) was led by the WHO and each country’s Ministry of Health team. Once selected, screening and training was jointly conducted by WHO, the Ministries of Health, and eHealth Africa team.
In several countries, “special informants” with limited literacy participate in the project via a simplified version of the app that only requires a “yes” or “no” response to having seen a child with AFP symptoms

This sourcebook aims to detail why health needs to be part of urban and territorial planning and how to make this happen. It brings together two vital elements we need to build habitable cities on a habitable planet: 1) Processes to guide the development of human settlements – in this document ref...erred to as “urban and territorial planning (UTP)”; and 2) concern for human health, well-being and health equity at all levels – from local to global, and from human to planetary health.
This sourcebook identifies a comprehensive selection of existing resources and tools to support the incorporation of health into UTP, including advocacy frameworks, entry points and guidance, as well as tools and illustrative case studies. It does not provide prescriptions for specific scenarios – these should be determined by context, people and available resources.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

Spread of resistance to antimicrobial agents (AMR) does not know national borders and has reached dimensions, which require immediate actions at the national, regional and global levels.
Antibiotic resistance is a natural biological response to improper use of antimicrobial agents (AMA); increasing... number of essential drugs, which become ineffective, contributing to selection, survival and replication of resistant strains of microorganisms. When chosen antimicrobials prove to be ineffective, the second- or third-line drugs need to be used although
in the majority of cases these drugs are more expensive, less safe and not always available.

Soil transmitted helminth (STH) infections are among the most common human infections worldwide with over 1 billion people affected. Many estimates of STH infection are often based on school-aged children (SAC). This study produced predictive risk-maps of STH on a more finite scale, estimated the nu...mber of people infected, and the amount of drug required for preventive chemotherapy (PC) in Ogun state, Nigeria. Georeferenced STH infection data obtained from a cross-sectional survey at 33 locations between July 2016 and November 2018, together with remotely-sensed environmental and socio-economic data were analyzed using Bayesian geostatistical modelling. Stepwise variable selection procedure was employed to select a parsimonious set of predictors to predict risk and spatial distribution of STH infections. The number of persons (pre-school ages children, SAC and adults) infected with STH were estimated, with the amount of tablets needed for preventive chemotherapy. An overall prevalence of 17.2% (95% CI 14.9, 19.5) was recorded for any STH infection. Ascaris lumbricoides infections was the most predominant, with an overall prevalence of 13.6% (95% CI 11.5, 15.7), while Hookworm and Trichuris trichiura had overall prevalence of 4.6% (95% CI 3.3, 5.9) and 1.7% (95% CI 0.9, 2.4), respectively. The model-based prevalence predictions ranged from 5.0 to 23.8% for Ascaris lumbricoides, from 2.0 to 14.5% for hookworms, and from 0.1 to 5.7% for Trichuris trichiura across the implementation units. The predictive maps revealed a spatial pattern of high risk in the central, western and on the border of Republic of Benin. The model identified soil pH, soil moisture and elevation as the main predictors of infection for A. lumbricoides, Hookworms and T. trichiura respectively. About 50% (10/20) of the implementation units require biannual rounds of mass drug administration. Approximately, a total of 1.1 million persons were infected and require 7.8 million doses. However, a sub-total of 375,374 SAC were estimated to be infected, requiring 2.7 million doses. Our predictive risk maps and estimated PC needs provide useful information for the elimination of STH, either for resource acquisition or identifying priority areas for delivery of interventions in Ogun State, Nigeria.

MICROBIAL DRUG RESISTANCEVolume 24, Number 5, 2018ªMary Ann Liebert, Inc.DOI: 10.1089/mdr.2017.0383
Antibiotic resistance (ABR) is a worldwide publichealth concern, with serious health, economic, and so-cietal repercussions. Its emergence is attributed to the se-lective pressure exerted by antib...iotic use in the community, hospitals, veterinary health, agriculture, aquaculture, and the environment. Additionally aggravating the situation is the fact that very few new antibiotics have recently been produced by pharmaceutical companies. It is widely acknowledged that food animals are key reservoirs of antibiotic-resistant bacteria and that antibiotic usage in this population favors the emergence, selection, and spread of resistance among animals and humans, both through zoonoses (infectious diseases trans-mitted between animals and humans) and the food chain.

La résistance aux antimicrobiens (ou RAM, cette abréviation étant est ici également employée en mode adjectif pour désigner les organismes « résistants aux antimicrobiens ») est une préoccupation majeure pour la santé publique mondiale et une question de sécurité san...itaire des aliments. Lorsque des pathogènes deviennent résistants aux agents antimicrobiens, ils peuvent présenter un risque plus important pour la santé découlant d’un éventuel échec thérapeutique, de la diminution de choix thérapeutiques et de la probabilité accrue d’apparition et de gravité de la maladie. Les problèmes en rapport avec la RAM sont liés de façon inhérente à l’usage des antimicrobiens dans tous les types d’environnements, y compris les utilisations humaines et non humaines. L'utilisation d’agents antimicrobiens dans la production alimentaire animale et végétale représente un facteur de risque important pour la sélection et la transmission de micro-organismes résistants aux antimicrobiens (micro-organismes RAM) et de déterminants de la résistance aux antimicrobiens (déterminants de la RAM) des animaux et des plantes alimentaires à l’humain par sa consommation d’aliments.
