These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

This updated glossary for malaria aims to improve communication and mutual understanding within the scientific community, as well as with funding agencies, public health officials responsible for malaria programmes, and policy-makers in malaria-endemic countries
WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

This document provides guidance to Member States in the WHO European Region that wish to conduct behavioural insights studies related to COVID-19. Studies can be used to monitor public knowledge, risk perceptions, behaviours and trust with the overall aim to inform national COVID-19 outbreak respons...e measures, including policies, interventions and communications.

WHO estimates that in 2015, 257 million people were living with chronic hepatitis B virus (HBV) infection worldwide, and that 900 000 died from HBV infection, mostly through the development of cirrhosis and hepatocellular carcinoma. Worldwide, the majority of persons with chronic hepatitis B infecti...on and associated deaths in adulthood acquired their infection at birth through mother-to-child perinatal transmission or in early childhood.

For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

Questão clínica: Qual é o papel dos corticosteroides sistêmicos no tratamento de pacientes com COVID-19? Público-alvo: O público-alvo consiste principalmente de médicos, seguido por tomadores de decisão na área de saúde.
As of 31 October 2020 This is the tenth edition of this summary of rapid systematic reviews, which includes the results of a rapid systematic review of currently available literature. More than 200 therapeutic options or their combinations are being investigated in more than 1,700 clinical trials. I...n this review, 46 therapeutic options are examined. The Pan American Health Organization (PAHO) is continually monitoring ongoing research on any possible therapeutic options. As evidence emerges, then PAHO will immediately assess and update its position, and particularly as it applies to any special sub-group populations such as children, expectant mothers, those with immune conditions, etc.

The report finds that, as of 3 November, in 87 countries with age-disaggregated data, children and adolescents under 20 years of age accounted for 1 in 9 of COVID-19 infections, or 11 per cent of the 25.7 million infections reported by these countries. More reliable, age-disaggregated data on infect...ion, deaths and testing is needed to better understand how the crisis impacts the most vulnerable children and guide the response

The growing understanding of how sequence information can contribute to improved public health is driving global investments in sequencing facilities and programmes. The falling cost and complexity of generating GSD provides opportunities for expanding sequencing capacity; however, challenges to wid...espread implementation remain. This document provides policy-makers and stakeholders with guidance on how to maximize the public health benefit of SARS-CoV-2 genomic sequencing activities in the short and long term as the pandemic continues to unfold. Practical considerations for the implementation of a virus genomic sequencing programme and an overview of the public health objectives of genomic sequencing are covered. This guidance focuses on SARS-CoV-2 but is applicable to other pathogens of public health concern.

As pandemias virais costumam representar sérias ameaças ao equilíbrio dos sistemas de saúde, ao impor-lhes demandas extraor-dinárias e sustentadas, que podem ultrapassar a capacidade de atendimento, no que diz respeito tanto aos insumos e às tecnologias disponíveis, quanto aos recurs...os humanos/profissionais capacitados. Trazem o enorme desafio de equilibrar igualdade entre as pessoas e equidade na distribuição de riscos e benefícios entre elas.
Diante desse cenário de casos cada vez mais frequentes de COVID-19 na
população, surge a premente necessidade de se avaliarem as melhores práticas para a otimização da utilização dos meios e recursos disponíveis. Dessa forma, considerando o iminente risco de indisponibilidade de leitos de terapia intensiva e respiradores para todos os indivíduos, acometidos ou não pela doença, torna-se fundamental estabelecer critérios clínicos, técnicos e éticos, para a melhor utilização dos mesmos, para se conseguir otimizar resultado e gerar o maior benefício possível.

The COVID-19 pandemic has impacted regular cardiovascular healthcare access and delivery. Service utilisation has declined, and excess cardiovascular mortality has been reported in several countries. We aim to estimate excess cardiovascular deaths in Chile during 2020.
Mortality due to enteric infections is projected to increase because of global warming; however, the different temperature sensitivities of major enteric pathogens have not yet been considered in projections on a global scale. We aimed to project global temperature-attributable enteric infection mor...tality under various future scenarios of sociodemographic development and climate change.
