This publication aims to provide updated guidance on the specific use of yellow fever laboratory assays in the context of surveillance to be used across the Global Yellow Fever Laboratory Network for disease surveillance. In the recent years, new commercial assays became available and are now recomm...ended for use by WHO and this publication will support national program on the use of compound laboratory assays as per the most recent recommended testing algorithms. This piece is aligned with the elimination effort set in the comprehensive global strategy to eliminate yellow fever epidemics (EYE) strategy 2017-2026 and where its advisory laboratory technical working group actively contributed to its development. The target audiences are policy-makers and health workers.

The waves of yellow fever transmission in the Region of the Americas in 2016–2018 involved the largest number of human and epizootic cases to be reported in several decades. Yellow fever is a serious viral hemorrhagic disease that poses a challenge for health professionals. It requires early recog...nition of signs and symptoms, which are often nonspecific, and it can mimic other acute febrile syndromes. Early detection of suspected or confirmed cases, monitoring of vital signs, life support measures, and treatment of acute kidney failure continue to be the recommended strategies for case management. This report is the result of discussions among experienced specialists in the Americas on the clinical management of yellow fever patients, especially during outbreaks and epidemics, in the context of current medical and scientific evidence and taking into account the technical guidelines already available in the countries of the Region. It includes flowcharts for initially addressing patients with clinical suspicion of yellow fever and proposes a minimum package of laboratory tests that may be useful in contexts where resources are limited. In addition, it considers aspects of health system organization for dealing with yellow fever outbreaks and epidemics.

This guide presents a basis for understanding how diarrhoeal diseases are currently influenced by climate and weather, and may be further exacerbated by climate change. It is a technical guide on how to conduct a Vulnerability & Adaptation assessment for diarrhoeal diseases and climate change, and p...rovides guidance on how to:
identify populations and regions vulnerable to diarrhoeal diseases and the reasons for their vulnerability;
establish relevant baselines that can be analysed and monitored;
conduct analyses to project how diarrhoeal diseases may be impacted in the future due to climate change; and
identify appropriate responses to mitigate and monitor these risks over time.

Cholera is an acute gastrointestinal infection caused by the bacterium Vibrio Cholerae serogroup O1 or O139, and is often linked to unsafe drinking water, lack of proper sanitation and personal hygiene. It adversely affects mostly the poor and vulnerable populations in countries, which are already d...eprived of proper health facilities and conducive environmental conditions. The disease spreads through oro-fecal transmission by the ingestion of contaminated food or water or by person-to-person contact. It has a short incubation period of 2 hours to 5 days and the number of affected cases can rapidly increase across large regions. Cholera is a significant threat to global public health leading to an estimated 3-5 million cases per year worldwide, with an annual toll of 100,000 deaths. The disease was first reported in 1817 from the Ganges Delta of India and since then the ongoing 7th pandemic has emerged from Indonesia, reached Africa in 1970 and Somalia happens to be one of the early affected countries. Over the past few decades,
Somalia has witnessed the occurrence of repeated AWD/Cholera disease outbreaks that have caused high morbidity and mortality across the country.

Information note. In 2021, preliminary results of observational studies from the Community Access to Rectal Artesunate for Malaria (CARAMAL) project did not confirm the mortality impact observed in the controlled trial in 2009. Consequently, in January 2022, WHO released an information note on recta...l artesunate (RAS), suggesting immediate risk mitigation measures. To provide clarity on the evidence, WHO subsequently convened independent experts to conduct a formal evidence review of the data from the CARAMAL project, as well as data from other studies evaluating the deployment of pre-referral RAS at programmatic level

The introduction of vaccines for coronavirus disease 2019 (COVID-19) added another measure to the existing set of
recommended preventive measures (wearing a mask in public, keeping a distance from other people and regular handwashing). The roll-out of the vaccines, however, raised concerns that vac...cination may lead to lower adherence to the existing
preventive measures. The advice from the World Health Organization (WHO) was to continue these public health and
social measures after being vaccinated.1 However, evidence from other epidemics suggests that there is lower adherence to
preventive measures when some level of protection exists (for example, individuals who use human immunodeficiency virus
pre-exposure prophylaxis

Building on the 2021 Interim guidance, this second version and update, incorporates the lessons and feedback from the hepatitis pilots that successfully demonstrated the feasibility of measuring hepatitis B and C impact targets to demonstrate elimination, whilst highlighting challenges caused by hig...h disease burden in some countries, as well as delays in reaching mortality targets due to the long natural history of disease progression to liver cirrhosis and hepatocellular carcinoma.
The path to elimination provides a framework with 3 levels of achievements for which WHO certification is available. Each stepwise progression from bronze to silver to gold tiers will promote an iterative expansion of prevention, diagnosis and treatment services for viral hepatitis services and strengthen measurement systems to support attainment of the 2030 elimination goals.
This updated version also includes changes, clarifications and new guidance on alternative measurement approaches for country validation of elimination. Through the validation process, WHO and partners continue to provide country support for strengthening health system capacity and patient-centred services that respect and protect the human rights of people living with viral hepatitis and ensures meaningful engagement of communities in the national, regional and global viral hepatitis response.

Vaccines are powerful weapons in the fight against pandemic viruses as shown by responses to both the 2009 H1N1 influenza and the COVID-19 pandemics. However, planning for accessing, allocating and deploying vaccines in a pandemic situation is a complex endeavour, beset with multiple challenges at a...ll levels – local, regional and global. The World Health Organization (WHO) and its partners have prepared this revised guidance document to assist countries update their national deployment and vaccination plans (NDVPs) by leveraging global learnings from past pandemic responses, including the recent COVID-19 vaccination effort. The development and testing of a NDVP would not only advance pandemic preparedness efforts but would also have benefits in terms of increasing national capabilities to manage other health emergencies which require emergency vaccination campaigns.

A varíola dos macacos é uma doença infeciosa emergente causada por um vírus transmitido aos humanos por animais infetados, na sua maioria roedores. Pode ser propagado a outras pessoas, mas a transmissão de pessoa para pessoa, isoladamente, não pode facilmente sustentar um surto. A apresentaç...o clínica é semelhante à observada no passado com a varíola, mas menos grave. A varíola foi erradicada mundialmente em 1980; no entanto, a varíola dos macacos ainda ocorre esporadicamente em partes da África Central e Ocidental, perto das florestas tropicais húmidas. Normalmente, a mortalidade nos surtos da varíola dos macacos tem sido de 1 a 10%, mas com os cuidados adequados, a maioria dos doentes recupera. Este curso fornece uma introdução geral à varíola dos macacos e destina-se aos profissionais de saúde responsáveis pela prevenção e controlo da varíola dos macacos.
