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

La fourniture de sang et de produits sanguins sûrs et efficaces pour la transfusion ou la fabrication d’autres produits sanguins fait intervenir un certain nombre de processus, allant de la sélection des donneurs de sang et de la collecte, au traitement et au dépistage des dons de sang ainsi qu...’à l’analyse des échantillons des malades, à la délivrance de sang compatible et à son administration au patient. Il existe un risque d’erreur à chaque étape de la « chaîne de transfusion », et une défaillance à une quelconque de ces étapes peut avoir des conséquences graves pour les receveurs du sang ou des produits sanguins. Si la transfusion sanguine peut sauver des vies, elle comporte aussi des risques, en particulier la transmission des infections par le sang.
Le dépistage des infections transmissibles par transfusion (ITT) en vue d’exclure les dons de sang présentant un risque de transmettre une infection du donneur aux receveurs est une étape critique du processus visant à garantir au mieux la sécurité des transfusions. Un dépistage efficace des agents transmissibles par le sang les plus courants et les plus dangereux peut réduire le risque de transmission à des niveaux très faibles.

The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and ...its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels.

La resistencia a los antimicrobianos (RAM, utilizado también como equivalente de "resistente a los antimicrobianos en este documento) constituye un importante motivo de preocupación mundial en el ámbito de la salud pública y un problema para la inocuidad de los alimentos. Cuando l...os patógenos se hacen resistentes a los agentes antimicrobianos, pueden ser más peligrosos para la salud humana a causa de un posible fracaso de los tratamientos, de la pérdida de opciones para los tratamientos y de la mayor probabilidad y gravedad de las enfermedades. Los problemas relacionados con la RAM están intrínsecamente relacionados con el uso de antimicrobianos en cualquier ámbito, lo que comprende los usos humanos y no humanos. El uso de agentes antimicrobianos en animales/cultivos destinados a la producción de alimentos constituye un factor potencialmente importante de riesgo de selección y propagación a los seres humanos de microorganismos resistentes y determinantes de RAM a partir de dichos cultivos/animales a través del consumo de alimentos.

The escalating antimicrobial resistance (AMR) pandemic is a global public health threat with extensive health, economic and societal implications. Resistance emerges because of selection pressure from rational and indiscriminate antimicrobial use in human health as well as in the veterinary, agricul...ture and environmental sectors. Infections caused by resistant bacteria result in longer duration of illness, higher mortality rates and increased costs associated with alternative treatment. AMR further constrains procedures that rely on antimicrobial prophylaxis, and AMR is recognized as a threat to theworld economy.

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.

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.

The article from the African Journal of Thoracic and Critical Care Medicine provides updated guidelines on endoscopic lung volume reduction (ELVR) for treating advanced emphysema, a severe form of chronic obstructive pulmonary disease (COPD), which is prevalent in South Africa and other low- and mid...dle-income countries. The guidelines focus on identifying suitable patients based on specific criteria, such as age, lung function, and the presence of hyperinflation, while ruling out contraindications like pulmonary hypertension and recent smoking.
ELVR aims to reduce lung volume in the most damaged areas, improving breathing mechanics and quality of life. Various devices, including endobronchial valves, intrabronchial valves, and coils, are reviewed with evidence from clinical trials supporting their use. The guidelines emphasize careful patient selection and recommend only performing ELVR in specialized centers due to its high cost and risk of complications, such as pneumothorax.
