Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

While many of the countries hit by the COVID-19 in the first few months of the year are now beginning to relax lockdown measures as infection and death rates fall, in the regions most affected by HIV, TB and malaria, such as Africa, South Asia and Latin America, the pandemic continues to accelerate.... In lower resource settings, lockdowns are less effective and hard to sustain, and clinical care facilities are extremely limited. In such environments, the response to COVID-19 must focus on containing the pandemic’s spread as far as possible through testing, contact tracing and isolation, protecting the health workforce through training and the provision of personal protective equipment (PPE) and minimizing the knock-on impact on other diseases through shoring up fragile health systems, and adapting existing disease programs.

n October 2019, WHO convened the first meeting of the Buruli ulcer laboratory network (BU-LABNET) in Yaoundé, Cameroon, bringing together 11 laboratories from nine countries at the Pasteur Centre of Cameroon (CPC), the network’s Coordinating Centre. The network was formally established at th...is meeting (1) and its members were those present. The objective of BU LABNET is to improve diagnosis of Buruli ulcer based on polymerase chain reaction (PCR) using standardized testing protocols, involving external quality assurance programmes and sharing knowledge among member laboratories.

HIV, viral hepatitis and STI epidemics, particularly among people who inject drugs and other key populations, continue to be fuelled by laws and policies criminalizing sex work; drug use or possession; diverse forms of gender expression and sexuality; stigma and discrimination; gender discrimination...; violence; lack of community empowerment and other violations of human rights. These sociostructural factors limit access to health services, constrain how these services are
delivered and diminish their effectiveness.

This paper explores access to water, sanitation, and health in pastoral communities in northern Tanzania. It argues that the concept of gender, used on its own, is not enough to understand the complexities of sanitation, hygiene, water, and health. It explores pastoralists’ views and perspectives ...on what is ‘clean’, ‘safe’, and ‘healthy’, and their need to access water and create sanitary arrangements that work for them, given the absence of state provision of modern water, sanitation, and hygiene (WASH) infrastructure. Although Tanzania is committed to enhancing its citizens’ access to WASH services, pastoral sanitation and hygiene tend to be overlooked and little attention is paid to complex ways in which access to ‘clean’ water and ‘adequate sanitation’ is structured in these communities. This paper offers an intersectional analysis of water and sanitation needs, showing how structural discrimination in the form of a lack of appropriate infrastructure, a range of sociocultural norms and values, and individual stratifiers interact to influence the sanitation and health needs of pastoralist men, women, boys, and girls.

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

Saúde Soc. São Paulo, v.30, n.1, e200450, 2021
Desde março de 2020, quando a Organização Mundial de Saúde declarou que o mundo vivia uma pandemia de covid-19, acompanhamos um quadro sanitário sem precedentes nos últimos 100 anos. As medidas atuais contra a ...doença têm como objetivo o controle da transmissão e envolvem ações individuais e coletivas de higiene e distanciamento físico, enquanto a busca por uma vacina se apresenta como a esperança para vencer a pandemia. Considerando o contexto social de clamor por uma nova vacina, este ensaio crítico discute o paradoxo e as contradições da relação indivíduo-sociedade no contexto da covid-19 à luz da hesitação vacinal como fenômeno histórico e socialmente situado. Este ensaio aponta que as tomadas de decisão sobre (não) vacinar ou sobre (não) seguir as medidas preventivas e de controle da propagação da covid-19 são conformadas por pertencimentos sociais e atravessadas por desigualdades que tendem a se exacerbar. A infodemia que cerca a covid-19 e a hesitação vacinal refletem a tensão entre o risco cientificamente validado e o risco percebido subjetivamente, também influenciada pela crise de confiança na ciência. Percepções de risco e adesão a medidas de saúde extrapolam aspectos subjetivos e racionais e espelham valores e crenças conformados pelas dimensões política, econômica e sociocultural.

One of the main aims of the WHO Global Initiative for Childhood Cancer and the CureAll Americas framework is to strengthen centers of excellence and promote the training of the health workforce, especially pediatric oncology nurses, specialized in nursing care for children and adolescents with cance...r and their families. These health personnel provide compassionate, non traumatic, complex, continuous, ethical, conscious patient- and family-centered care in order to meet the physical, emotional, psychosocial, and cultural needs of the people involved. This publication is aimed at health administration teams, hospital management teams, and professional pediatric oncology nursing groups. Its objective is to identify, systematize, and consolidate available evidence on the scope of pediatric oncology nursing practice in Latin America and the Caribbean based on core competencies, in order to incorporate them into clinical practice, teaching, and research. The preparation process included a systematic review aimed at finding the best evidence on this subject. Patient- and family centered care and the conceptual model of competencies for teenagers and young adults with cancer, developed by the Teenage Cancer Trust with the support of the Royal College of Nursing, were the theoretical foundations supporting the systematization of recommendations.
