Difteria en las Américas – Resumen de la situación
Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

This technical document consists of epidemiological profiles (fact-sheets) for States and districts based on information available from multiple d...ata sources including the HIV Sentinel Surveillance (HSS) and the Integrated Biological and Behavioural Surveillance (IBBS). Given the need for focussed prevention efforts in low/high prevalence and vulnerable States/districts, the information presented will be useful for policy makers, program planners at national/State/ district level, researchers, and academicians in identification of areas for priority attention and also to derive meaningful conclusions for programme planning, implementation, monitoring and scale-up. This document will be a quick reference for the HIV/AIDS situation in a State/district, risk and safe behaviour of the high risk groups, their level of knowledge about STIs and HIV/AIDS, experience of violence, HIV testing and ART awareness and exposure to HIV/AIDS prevention.

L’orthopoxvirose simienne, aussi connu sous les noms de variole du singe ou monkeypox, est une zoonose causée par l'orthopoxvirus simien et reconnue comme l'infection à orthopoxvirus la plus importante depuis l'éradication de la variole.
Ce cours offre aux personnel de santé publique et aux a...gents de santé des informations approfondies pour comprendre l'épidémiologie, les modes de transmission, la présentation clinique, le diagnostic et le traitement de la variole du singe, ainsi que les stratégies nécessaires pour la prévention, Ce cours offer aussi des suggestions pour mener une enquête et mettre en oeuvre une réponse efficace à une flambée de variole du singe.

Monitoramento efetivo, avaliação epidemiológica e análise subsequente são
necessários para atingir o objetivo de interromper a transmissão da FL. Este manual foi
elaborado para oferecer aos programas nacionais de eliminação da fi lariose informação de qualidade sobre metodologias e proc...edimentos para monitoramento dos TC, avaliação adequada sobre se e quando ocorreu redução da infecção a níveis em que a transmissão provavelmente não é mais sustentável, implementação de vigilância adequada após a interrupção dos TCs para estabelecer se está ocorrendo recrudescência e medidas para comprovação da ausência de transmissão. O Manual oferece orientação geral aos programas nacionais e informações relevantes sobre questões técnicas são apresentadas nos anexos. Como as circunstâncias da vida real podem não corresponder a categorias pré-defi nidas, recomenda-se que se consultem a OMS e especialistas em situações complexas.
