Despite the human and economic impact of viral epidemics, the world is not well enough prepared for the next emerging viral outbreak. Global trends indicate that new microbial threats will continue to emerge at an accelerating rate, driven by our growing population, expanded travel and trade network...s, and human encroachment into wildlife habitat.

Méthodologie pour l’élaboration d’un plan stratégique national
Principales composantes du PSN
Un Plan humanitaire multisectoriel spécifique à la réponse COVID-19 a été développé en avril 2020 et constitue un Addendum au Plan de réponse humanitaire 2020 (PRH) afin d’intégrer l’impact de la pandémie de COVID-19 sur les besoins humanitaires existants et sur les activités des part...enaires humanitaires en République Démocratique du Congo (RDC).

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

Clinical management handbook
This document was prepared in response to a need to review and potentially update the current recommendations for the antibiotic treatment of both inpatient and outpatient management of severe acute malnutrition (SAM). The current recommendations (Table 1) are based on guidelines published in 2013 i...n the WHO Pocketbook for Hospital Care for Children, and the 2013 update on SAM (outpatient management). The global threat of increasing antimicrobial resistance and new data on efficacy and safety profiles requires a re-review of the current evidence to ensure recommendations are the most appropriate. The evidence base for the use of antibiotics in children presenting with uncomplicated SAM has been recently enlarged.

Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.

La Guinée a été le point zéro de la flambée récente de la maladie à virus Ebola. Le taux de mortalité attribuée à Ebola en Guinée était de 66 %, nettement plus élevé que les taux des deux autres pays ouest-africains les plus affectés : la Sierra Leone (32 %) et le Liberia (45 %). Face... à la fermeture des cliniques, aux patients qui évitent les établissements sanitaires de peur de contracter Ebola et aux patients présentant des symptômes semblables à ceux d’Ebola qu’on renvoie chez eux, les experts en matière de santé s’inquiètent que d’autres maladies, telles que le paludisme, la pneumonie et la fièvre typhoïde, ne seront pas soignées, et que des soins de routine comme ceux qui favorisent la santé maternelle et infantile ne seront pas fournis.
