The WHO COVID-19 Essential Supplies Forecasting Tool (COVID-19-ESFT) is meant to help countries forecast essential supplies for their COVID-19 response including personal protective equipment (e.g., masks and gloves), biomedical equipment for case management (e.g., ventilators and oxygen concentrato...rs), diagnostic reagents and equipment, essential drugs for supportive care, and consumable medical supplies.
The tool is best suited for estimating essential supply needs over a short time period (12 weeks or fewer) but can be used for longer.
COVID-19-ESFT does not quantify or account for resources already available locally or those pending delivery. When using the ESFT to inform procurement, we recommend factoring in resources already available locally and only including the additional resources required in the forecast.
This tool is updated regularly so users should monitor the website for the latest release version.

Os sistemas de saúde estão enfrentando um rápido aumento na demanda gerada pelo surto da COVID-19. Quando os sistemas de saúde ficam sobrecarregados, há um aumento drástico na mortalidade direta causada por um surto e também na mortalidade indireta por doenças imunopreveníveis e por aquelas... doenças que possuem tratamento. Análises do surto de ebola em 2014-2015 sugerem que o aumento no número de óbitos causados por sarampo, malária, HIV/AIDS e tuberculose atribuíveis a falhas no sistema de saúde ultrapassou o número de óbitos causados pelo ebola. A capacidade de um sistema de manter a prestação de serviços essenciais de saúde dependerá de sua capacidade inicial e da carga da doença e do contexto de transmissão do vírus COVID-19 (classificado como nenhum caso, transmissão esporádica, em clusters ou comunitária). Manter a confiança da população na capacidade do sistema de saúde de atender, com segurança, as necessidades essenciais e de controlar o risco de infecção nas unidades de saúde é fundamental para garantir que as pessoas continuem a buscar atendimento quando necessário e que sigam as orientações de saúde pública.

Nigeria’s healthcare system faces significant challenges in financing and quality, impacting the delivery of services to its growing population. This study investigates healthcare workers’ perceptions of these challenges and their implications for healthcare policy and practice. A cross-sectiona...l survey was conducted with 600 healthcare professionals from eight states across Nigeria, representing a variety of healthcare occupations. Participants completed a questionnaire that assessed their perceptions of healthcare financing, quality of care, job satisfaction, and motivation using a 5-point Likert scale, closed- and open-ended questions. Descriptive statistics, Chi-squared test, and regression analysis were used to analyze the data. The findings revealed that healthcare workers were generally not satisfied with the current state of healthcare financing and system quality in Nigeria. Poor funding, inadequate infrastructure, insufficient staffing, and limited access to essential resources were identified as major challenges.

The IFRC Psychosocial Centre has published a guidance note providing an overview of the psychosocial consequences of virus outbreaks, with a focus on mpox, and outlines key considerations for MHPSS programming.
The current mpox outbreaks present numerous challenges for responding National Societi...es. A key issue is addressing stigma as individuals infected, or suspected of having mpox may experience social ostracization, discrimination, and even violence. In many African communities, where cultural and social norms are vital to community health, considering the cultural and psychosocial implications of virus outbreaks is integral for effective disease management. In addition, Red Cross Red Crescent staff and volunteers may be personally exposed and working in complex environments with rumours and misinformation generating fear and anxiety. This guidance addresses the key mental health and psychosocial support implications of the ongoing mpox crisis.
Guleed Dualeh, MHPSS Advisor
This guidance note is intended for Red Cross Red Crescent National Societies and IFRC departments who may be responding to mpox in their country, or region. It includes guidance on:
Common reactions and behaviours in epidemics
Caring for staff and volunteers in health emergencies
Integration of MHPSS considerations for into health responses

INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

WHO today released its first roadmap to tackle postpartum haemorrhage (PPH) – defined as excessive bleeding after childbirth - which affects millions of women annually and is the world’s leading cause of maternal deaths.
Despite being preventable and treatable, PPH results in around 70 000 de...aths every year. For those who survive, it can cause disabilities and psychological trauma that last for years.
“Severe bleeding in childbirth is one of the most common causes of maternal mortality, yet it is highly preventable and treatable,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This new roadmap charts a path forward to a world in which more women have a safe birth and a healthy future with their families.”
The Roadmap aims to help countries address stark differences in survival outcomes from PPH, which reflect major inequities in access to essential health services. Over 85% of deaths from PPH happen in sub-Saharan Africa and South Asia. Risk factors include anaemia, placental abnormalities, and other complications in pregnancy such as infections and pre-eclampsia.
Many risk factors can be managed if there is quality antenatal care, including access to ultrasound, alongside effective monitoring in the hours after birth. If bleeding starts, it also needs to be detected and treated extremely quickly. Too often, however, health facilities lack necessary healthcare workers or resources, including lifesaving commodities such as oxytocin, tranexamic acid or blood for transfusions.
“Addressing postpartum haemorrhage needs a multipronged approach focusing on both prevention and response - preventing risk factors and providing immediate access to treatments when needed - alongside broader efforts to strengthen women’s rights,” said Dr Pascale Allotey, WHO Director for Sexual and Reproductive Health and HRP, the UN’s special programme on research development and training in human reproduction. “Every woman, no matter where she lives, should have access to timely, high quality maternity care, with trained health workers, essential equipment and shelves stocked with appropriate and effective commodities – this is crucial for treating postpartum bleeding and reducing maternal deaths.”

Principaux faits
D’après les estimations, 6 à 7 millions de personnes dans le monde sont infectées par Trypanosoma cruzi (T. Cruzi), le parasite responsable de la maladie de Chagas. La plupart de ces personnes vivent en Amérique latine.
La transmission à l’être humain se fait principalem...ent, en Amérique latine, par l’intermédiaire d’un insecte appelé triatome, qui peut être porteur de T. cruzi.
Parmi les autres modes de transmission de la maladie de Chagas, figurent : la transmission orale (par voie alimentaire), la transfusion de sang ou de produits sanguins, la transmission mère-enfant (congénitale), la transplantation d’organes et les accidents de laboratoire.
La maladie de Chagas ne touchait auparavant que des zones rurales de la Région des Amériques, et surtout de l’Amérique latine. Ces dernières décennies, toutefois, les mouvements de population ont fait que la plupart des personnes infectées sont des habitants de zones urbaines (urbanisation) et que la maladie s’est propagée à d’autres continents (où T. cruzi se transmet par des voies non vectorielles).
L’infection à T. cruzi est curable si un traitement est instauré rapidement après l’infection.
Chez les personnes infectées de façon chronique, un traitement antiparasitaire peut éventuellement prévenir ou enrayer la progression de la maladie, et éviter sa transmission, notamment de la mère à l’enfant.
Jusqu’à 30 % des personnes infectées de façon chronique présentent des troubles cardiaques, et jusqu’à 10 % d’entre elles souffrent de troubles digestifs et/ou neurologiques, ce qui peut imposer un traitement particulier.
Les principales méthodes de prévention de la maladie de Chagas en Amérique latine sont la lutte antivectorielle ainsi que d’autres stratégies visant à réduire la transmission vectorielle.
Dans le monde entier, le dépistage sanguin joue un rôle crucial dans la prévention de l’infection par transfusion ou transplantation d’organes.
Il est essentiel de détecter et de traiter l’infection chez les femmes et les filles en âge de procréer, ainsi que de soumettre tout nouveau-né et ses frères et sœurs à un dépistage dans le cas où la mère est infectée et n’a jamais reçu de traitement antiparasitaire.
Certains facteurs socio-économiques et environnementaux influent fortement sur la maladie de Chagas, dont la propagation et les différentes dimensions interdépendantes justifient la nécessité de mettre en œuvre des stratégies de lutte multisectorielles.
Quelques pays ont mis en place la notification et la surveillance des cas aigus et chroniques et des voies de transmission actives, qui sont essentielles à la lutte contre la maladie de Chagas.

KEY MESSAGES
Always talk to a GBV specialist first to understand what GBV services are available in your area. Some services may take the form of hotlines, a mobile app or other remote support.
Be aware of any other available services in your area. Identify services provided by humanitarian pa...rtners such as health, psychosocial support, shelter and non-food items. Consider services provided by communities such as mosques/ churches, women’s groups and Disability Service Organizations.
Remember your role. Provide a listening ear, free of judgment. Provide accurate, up-to-date information on available services. Let the survivor make their own choices. Know what you can and cannot manage. Even without a GBV actor in your area, there may be other partners, such as a child protection or mental health specialist, who can support survivors that require additional attention and support. Ask the survivor for permission before connecting them to anyone else. Do not force the survivor if s/he says no.
Do not proactively identify or seek out GBV survivors. Be available in case someone asks for support.
Remember your mandate. All humanitarian practitioners are mandated to provide non-judgmental and non-discriminatory support to people in need regardless of: gender, sexual orientation, gender identity, marital status, disability status, age, ethnicity/tribe/race/religion, who perpetrated/committed violence, and the situation in which violence was committed. Use a survivor-centered approach by practicing:
Respect: all actions you take are guided by respect for the survivor’s choices, wishes, rights and dignity.
Safety: the safety of the survivor is the number one priority.
Confidentiality: people have the right to choose to whom they will or will not tell their story. Maintaining confidentiality means not sharing any information to anyone.
Non-discrimination: providing equal and fair treatment to anyone in need of support.
If health services exist, always provide information on what is available. Share what you know, and most importantly explain what you do not. Let the survivor decide if s/he wants to access them. Receiving quality medical care within 72 hours can prevent transmission of sexually transmitted infections (STIs), and within 120 hours can prevent unwanted pregnancy.
Provide the opportunity for people with disabilities to communicate to you without the presence of their caregiver, if wished and does not endanger or create tension in that relationship.
If a man or boy is raped it does not mean he is gay or bisexual. Gender-based violence is based on power, not someone’s sexuality.
Sexual and gender minorities are often at increased risk of harm and violence due to their sexual orientation and/or gender identity. Actively listen and seek to support all survivors.
Anyone can commit an act of gender-based violence including a spouse, intimate partner, family member, caregiver, in-law, stranger, parent or someone who is exchanging money or goods for a sexual act.
Anyone can be a survivor of gender-based violence – this includes, but isn’t limited to, people who are married, elderly individuals or people who engage in sex work.
Protect the identity and safety of a survivor. Do not write down, take pictures or verbally share any personal/identifying information about a survivor or their experience, including with your supervisor. Put phones and computers away to avoid concern that a survivor’s voice is being recorded.
Personal/identifying information includes the survivor’s name, perpetrator(s) name, date of birth, registration number, home address, work address, location where their children go to school, the exact time and place the incident took place etc.
Share general, non-identifying information
To your team or sector partners in an effort to make your program safer.
To your support network when seeking self-care and encouragement.

BACKGROUND: Growing political attention to antimicrobial resistance (AMR) offers a rare opportunity for achieving meaningful action. Many governments have developed national AMR action plans, but most have not yet implemented policy interventions to reduce antimicrobial overuse. A systematic evidenc...e map can support governments in making evidence-informed decisions about implementing programs to reduce AMR, by identifying, describing, and assessing the full range of evaluated government policy options to reduce antimicrobial use in humans.
METHODS AND FINDINGS: Seven databases were searched from inception to January 28, 2019, (MEDLINE, CINAHL, EMBASE, PAIS Index, Cochrane Central Register of Controlled Trials, Web of Science, and PubMed). We identified studies that (1) clearly described a government policy intervention aimed at reducing human antimicrobial use, and (2) applied a quantitative design to measure the impact. We found 69 unique evaluations of government policy interventions carried out across 4 of the 6 WHO regions. These evaluations included randomized controlled trials (n = 4), non-randomized controlled trials (n = 3), controlled before-and-after designs (n = 7), interrupted time series designs (n = 25), uncontrolled before-and-after designs (n = 18), descriptive designs (n = 10), and cohort designs (n = 2). From these we identified 17 unique policy options for governments to reduce the human use of antimicrobials. Many studies evaluated public awareness campaigns (n = 17) and antimicrobial guidelines (n = 13); however, others offered different policy options such as professional regulation, restricted reimbursement, pay for performance, and prescription requirements. Identifying these policies can inform the development of future policies and evaluations in different contexts and health systems. Limitations of our study include the possible omission of unpublished initiatives, and that policies not evaluated with respect to antimicrobial use have not been captured in this review.
CONCLUSIONS: To our knowledge this is the first study to provide policy makers with synthesized evidence on specific government policy interventions addressing AMR. In the future, governments should ensure that AMR policy interventions are evaluated using rigorous study designs and that study results are published.

The development of this Operational Roadmap has been driven by a growing consensus in Ukraine on the need to prioritize activities that are urgently required to address the mental health and psychosocial needs of the country’s population and also the importance of basing the response on existing s...tructures, resources and innovations introduced in reforms in past years.
According to this consensus, new resources mobilized by and for Ukraine should complement existing ones, in line with the national vision and with best international standards, and should be planned in a way that further strengthens the country’s mental health system.
The Government of Ukraine is committed to urgently addressing the mental health and psychosocial needs of the population, under the auspices of the First Lady of Ukraine and the leadership of the recently established Intersectoral Coordination Council for Mental Health and Psychological Assistance to Victims of the Armed Aggression of the Russian Federation against Ukraine (referred to in this document as the Intersectoral Coordination Council).
This Roadmap has been developed following a series of consultations with Ukrainian authorities and national and international agencies working in the area of mental health and psychosocial support (MHPSS) and engaged in emergency response in Ukraine. The consultation process was organized by the Ministry of Health of Ukraine (MOH) and supported by WHO Ukraine, under the auspices of the First Lady of Ukraine and in collaboration with the MHPSS Technical Working Group of Ukraine (MHPSS TWG Ukraine) and the IASC MHPSS Reference Group (IASC MHPSS RG), and building on substantial advances in the mental health sector under existing programmes in the country.
The Roadmap is informed by international technical guidance and national policies and plans, including the IASC Guidelines on MHPSS in Emergency Settings, the Minimum Services Package for MHPSS in Emergencies (MHPSS MSP), the IASC Common Monitoring and Evaluation Framework, the World Health Organization (WHO)’s Comprehensive Mental Health Action Plan 2013– 2030, the WHO European Framework for Action on Mental Health, the Concept for Development of Mental Health Care in Ukraine until 2030, the National Mental Health Action Plan for 2021–2023 and the National Recovery and Development Plan.
Informed by the overall goal of MHPSS assistance in Ukraine – to reduce suffering and improve the mental health and psychosocial well-being of the affected population – the Roadmap aims to provide a consolidated overview of envisioned MHPSS priorities, informed by the local context and the vision of the Government of Ukraine together with national and international partners, and with the best available evidence and resources, to all MHPSS stakeholders already engaged in or joining emergency response and recovery efforts in Ukraine.
As well as information on the context in Ukraine, the Roadmap includes:
• a list of evidence-based MHPSS interventions and services contextualized and introduced in Ukraine in recent years (described in Table 1) and
• a set of multisectoral actions to scale up MHPSS services in both the short and longer terms, informed by available evidence, international technical guidance and expert consensus (described in Table 2).

The second ECDC/EFSA/EMA joint report on the integrated analysis of antimicrobial consumption (AMC) and antimicrobial resistance (AMR) in bacteria from humans and food-producing animals addressed data obtained by the Agencies’ EU-wide surveillance networks for 2013–2015. AMC in both sectors, exp...ressed in mg/kg of estimated biomass, were compared at country and European level. Substantial variations between countries were observed in both sectors. Estimated data on AMC for pigs and poultry were used for the first time. Univariate and multivariate analyses were applied to study associations between AMC and AMR. In 2014, the average AMC was higher in animals (152 mg/kg) than in humans (124 mg/kg), but the opposite applied to the median AMC (67 and 118 mg/kg, respectively). In 18 of 28 countries, AMC was lower in animals than in humans. Univariate analysis showed statistically-significant (p < 0.05) associations between AMC and AMR for fluoroquinolones and Escherichia coli in both sectors, for 3rd- and 4th-generation cephalosporins and E. coli in humans, and tetracyclines and polymyxins and E. coli in animals. In humans, there was a statistically-significant association between AMC and AMR for carbapenems and polymyxins in Klebsiella pneumoniae. Consumption of macrolides in animals was significantly associated with macrolide resistance in Campylobacter coli in animals and humans. Multivariate analyses provided a unique approach to assess the contributions of AMC in humans and animals and AMR in bacteria from animals to AMR in bacteria from humans. Multivariate analyses demonstrated that 3rd- and 4th-generation cephalosporin and fluoroquinolone resistance in E. coli from humans was associated with corresponding AMC in humans, whereas resistance to fluoroquinolones in Salmonella spp. and Campylobacter spp. from humans was related to consumption of fluoroquinolones in animals. These results suggest that from a ‘One-health’ perspective, there is potential in both sectors to further develop prudent use of antimicrobials and thereby reduce AMR.

La enfermedad de Chagas, también llamada tripanosomiasis americana, sigue siendo endémica en 21 países de América Latina. Sin embargo, como consecuencia de las migraciones, la urbanización, la intensificación del turismo, la modificación de las estrategias agrícolas y el cambio climático, l...a enfermedad ha traspasado el marco rural y el ámbito latinoamericano que le dieron identidad durante decenios, y ha logrado instalarse en la periferia de las ciudades del área endémica y en países de América del Norte, Europa, Asia y Oceanía y transformarse en un problema de salud pública global. Teniendo en cuenta que el Chagas afecta a poblaciones en situación de pobreza en las que produce graves consecuencias para la salud y la economía de las personas infectadas, y que los recursos orientados a fomentar el desarrollo de proyectos de investigación, estrategias de control y planes de atención médica a los pacientes detectados son escasos, la Organización Mundial de la Salud (OMS) incorporó esta enfermedad al grupo de enfermedades infecciosas desatendidas (EID) en el año 2005. Se reconoce actualmente la naturaleza multidimensional de la enfermedad de Chagas, cuya caracterización contempla una intrincada trama de aspectos socioculturales, políticos, biológicos, ambientales y sanitarios. Parte sustancial de todo ello radica en el carácter zoonótico de la endemia y la consiguiente imposibilidad de su erradicación. Por ende, resulta muy complicada la construcción de la ruta crítica para enfrentar esta enfermedad, con la aspiración o el objetivo de su eliminación como problema de salud pública. El propósito de esta guía es ofrecer a los Estados Miembros un instrumento que permita actualizar y estandarizar los procesos de evaluación del control, verificación de la interrupción de la transmisión, y validación de la eliminación de la enfermedad de Chagas como problema de salud pública, en consonancia con: a) la Estrategia y plan de acción para la prevención, el control y la atención de la enfermedad de Chagas; b) el Plan de acción para la eliminación de las enfermedades infecciosas desatendidas y las medidas posteriores a la eliminación 2016-2022; c) el Plan de acción sobre entomología y control de vectores 2018-2023; d) guías o procedimientos operativos estandarizados existentes para la verificación o validación de la eliminación de otras enfermedades infecciosas desatendidas (EID) como la oncocercosis, la filariasis linfática y el tracoma, y e) Enfermedades tropicales desatendidas. Prevención, control, eliminación, erradicación.

We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in ...the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges, supporting a cost-effective IVS strategy for early warning of CL outbreaks through an environmental modification alert network, which includes multiple sources of information and actors. In relation to VL, the earliest colonization sites and spatial distribution were explained by modeling and forecasting the most likely hotspots, persistent in time and space, and modulated by environmental variables. Therefore, for VL, a scalar strategy of critical site selection is proposed from a “city” scale based on secondary sources such as remote sensing for the definition of possible areas to monitor and intervene, a scale of restriction from possible to most likely areas through local knowledge, and a “focal site” scale of trap placement through field observation; in this way, IVS activities are carried out at a few sites of the urban landscape and allow a sustainable program.
