Le cycle de transmission
Téniase. Les ténias vivent dans l’intestin des êtres humains. Les œufs du ténia sont libérés avec les matières fécales. En cas de défécation à l’air libre, l'environnement (en particulier les légumes et l'eau) peut être contaminé. Cysti...cercose humaine. L'ingestion d'œufs de ténia (due à une mauvaise hygiène après l'utilisation des toilettes ou à la consommation d'eau ou d'aliments contaminés), entraîne le développement de kystes parasitaires principalement dans le cerveau (provoquant notamment des crises d’épilepsie). Cysticercose porcine. Les porcs mangeant des œufs de ténia (présents dans les matières fécales ou l'environnement) développent des kystes parasitaires principalement dans les muscles (viande). La viande infectée contient des kystes parasitaires qui ne sont pas toujours faciles à voir. La consommation de viande de porc infectée, crue ou mal cuite, entraîne le développement du ténia.
Les mesures de prévention et de contrôle
Les médicaments prescrits dans les centres de santé peuvent traiter l'infection par le ténia. Lavez vos mains avec de l'eau et du savon après avoir utilisé les toilettes. Rincez soigneusement les légumes ou faites-les cuire avant de les manger. Utilisez les toilettes ou les latrines pour éviter la contamination de l'environnement, des porcs et des autres personnes. Garder les porcs dans des enclos pour les empêcher d’être infectés. Vaccinez et traitez les porcs pour prévenir l'infection. L'inspection des viandes permet d'identifier les porcs fortement infectés. Faites bien cuire la viande de porc (elle ne doit plus être rose) pour tuer le parasite.

La résistance aux antimicrobiens Esurvient lorsque les micro-organismes (bactéries, champignons, virus et parasites) évoluent quand ils sont exposés à des médicaments antimicrobiens (comme les antibiotiques, les antifongiques, les antiviraux, les antipaludiques et les anthelminthiques).
On ap...pelle parfois «super bactéries» celles qui développent une résistance aux antimicrobiens, mais cela concerne tous les micro-organismes.
En conséquence, les médicaments perdent leur efficacité et les infections persistent dans l’organisme, augmentant le risque de transmission à d’autres personnes.

Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.

The document "Diabetes in Pregnancy" by NICE (National Institute for Health and Care Excellence) outlines quality standards for managing diabetes in women during pregnancy, with a focus on five key areas. First, it emphasizes the importance of preconception planning for women of childbearing age wit...h diabetes. These women should receive guidance on optimizing their health before pregnancy, including achieving target HbA1c levels and taking high-dose folic acid to minimize risks. Second, joint diabetes and antenatal care is recommended for pregnant women with pre-existing diabetes, who should be seen early in pregnancy (ideally by 10 weeks gestation) by a combined diabetes and antenatal team to ensure optimal care throughout their pregnancy.
The third focus area is continuous glucose monitoring (CGM), which should be offered to pregnant women with type 1 diabetes. This includes either real-time CGM or flash monitoring to help improve blood glucose control and reduce complications during pregnancy. Fourth, postnatal testing and referral are essential for women diagnosed with gestational diabetes, who should receive glucose testing after birth to detect any persistent diabetes. Those eligible are referred to the National Diabetes Prevention Programme to lower their risk of developing type 2 diabetes. Lastly, the document recommends annual HbA1c testing for women with a history of gestational diabetes to monitor for type 2 diabetes development.
These standards aim to improve pregnancy outcomes for women with diabetes by providing individualized, accessible, and culturally appropriate care.

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

To survive and thrive, children and adolescents need good health, adequate nutrition, security, safety and a supportive clean environment, opportunities for early learning and education, responsive relationships and connectedness, and opportunities for personal autonomy and self-realization. To prom...ote their health and wellbeing, children and adolescents need support from parents, families, communities, surrounding institutions, and an enabling environment. Scheduled well care visits provide a critical opportunity for support of individual children, adolescents, parents, caregivers and families promote health and wellbeing. This guidance on scheduled child and adolescent well-care visits is the first in a series of publications to support the operationalization of the comprehensive agenda for child and adolescent health and wellbeing. It provides guidance on what is required to strengthen health systems and services to ensure healthy growth and development of all children and adolescents, and to support their parents and caregivers.
The guidance focuses on scheduled routine contacts with providers to support children and adolescents in their growth and developmental trajectory, as well as their primary caregivers and families. It outlines the rationale and objectives of well care visits and proposes a minimum 17 scheduled visits; describes the expected tasks during a contact; provides age-specific content to be address during each contact; and proposes actions to build on and maximize existing opportunities and resources.

The World Heart Federation (WHF) Roadmap series covers a large range of cardiovascular conditions. These Roadmaps identify potential roadblocks and their solutions to improve the prevention, detection and management of cardiovascular diseases and provide a generic global framework available for loca...l adaptation. A first Roadmap on raised blood pressure was published in 2015. Since then, advances in hypertension have included the publication of new clinical guidelines (AHA/ACC; ESC; ESH/ISH); the launch of the WHO Global HEARTS Initiative in 2016 and the associated Resolve to Save Lives (RTSL) initiative in 2017; the inclusion of single-pill combinations on the WHO Essential
Medicines’ list as well as various advances in technology, in particular telemedicine and mobile health. Given the substantial benefit accrued from effective interventions in the management of hypertension and their potential for scalability in low and middle-income countries (LMICs), the WHF has now revisited and updated the ‘Roadmap for raised BP’ as ‘Roadmap for hypertension’
by incorporating new developments in science and policy. Even though cost-effective lifestyle and medical interventions to prevent and manage hypertension exist, uptake is still low, particularly in resource-poor areas. This Roadmap examined the roadblocks pertaining to both the demand side (demographic and socio-economic factors, knowledge and beliefs, social relations, norms, and
traditions) and the supply side (health systems resources and processes) along the patient pathway to propose a range of possible solutions to overcoming them. Those include the development of population-wide prevention and control programmes; the implementation of opportunistic screening and of out-of-office blood pressure measurements; the strengthening of primary care and a greater focus on task sharing and team-based care; the delivery of people-centred care and stronger patient and carer education; and the facilitation of adherence to treatment. All of the above are dependent upon the availability and effective distribution of good quality, evidencebased, inexpensive BP-lowering agents.

Cardiovascular diseases (CVD) represent the highest burden of disease globally. Medicines are a critical intervention used to prevent and treat CVD. This review describes access to medication for CVD from a health system perspective and strategies that have been used to promote access, including pro...viding medicines at lower cost, improving medication supply, ensuring medicine quality, promoting appropriate use, and managing intellectual property issues. Using key evidence in published and gray literature and systematic reviews, we summarize advances in access to cardiovascular medicines using the 5 health system dimensions of access: availability, affordability, accessibility, acceptability, and quality of medicines. There are multiple barriers to access of CVD medicines, particularly in low- and middle-income countries. Low availability of CVD medicines has been reported in public and private healthcare facilities. When patients lack insurance and pay out of pocket to purchase medicines, medicines can be unaffordable. Accessibility and acceptability are low for medicines used in secondary prevention; increasing use is positively related to country income. Fixed-dose combinations have shown a positive effect on adherence and intermediate outcome measures such as blood pressure and cholesterol. We have a new opportunity to improve access to CVD medicines by using strategies such as efficient procurement of low-cost, quality-assured generic medicines, development of fixed-dose combination medicines, and promotion of adherence through insurance schemes that waive copayment for long-term medications. Monitoring progress at all levels, institutional, regional, national, and international, is vital to identifying gaps in access and implementing adequate policies.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Severe and difficult asthma in a low- and middle-income country (LMIC) can relate to lack of availability of basic medications; potentially reversible factors such as poor adherence or comorbidities such as obesity inhibiting a good response to treatment; and (rarely) true severe, therapy-resistant ...asthma. However, definitions of severity should encompass not merely doses of prescribed medication, but also underlying risk. The nature of asthmatic airway disease shows geographical variation, and LMIC asthma should not be assumed to be phenotypically the same as that in high-income countries (HICs). The first assessment step is to ensure another diagnosis is not being missed. Largely, political action is needed if children with asthma are to get access to basic medications. If a child is apparently not responding to low dose, simple medications, the next step is not to increase the dose but perform a detailed assessment of what factors (for example co-morbidities such as obesity, or social factors like poor adherence) are inhibiting a treatment response; in most cases, an underlying reason can be found. An assessment of risk of future severe asthma attacks, side-effects of medication and impaired lung development is also important. True severe, therapy-resistant asthma is rare and there are multiple underlying molecular pathologies. In HICs, steroid-resistant eosinophilia would be treated with omalizumab or mepolizumab, but the cost of these is prohibitive in LMICs, the biomarkers of successful therapy are likely only relevant to HICs. In LMICs, a raised blood eosinophil count may be due to parasites, so treating asthma based on the blood eosinophil count may not be appropriate in these settings.

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.”

It is widely understood that the food insecurity crisis in the Sahel and the Horn of Africa is one of the world’s fastest growing and most neglected crises. It lacks sufficient global focus, resources and urgency. As in so many crises, women and girls are disproportionately affected and shoulder t...he consequences of protracted neglect, with unconscionable impacts on their safety, life chances and agency.
Gaining a holistic view of the gendered drivers, risks and impacts of food insecurity in the Sahel and the Horn of Africa is difficult. This is due to a lack of data and prioritization, and the large geographical and socioeconomic terrain covered by both regions. However, what we do know about this crisis is more than enough to urgently address the needs of women and girls.
An OCHA discussion paper on this topic (which will be published imminently, and from which this policy brief is drawn) found that there is:
A strong risk of profound regression in gender equality gains made to date in the countries of concern, including on education, sexual and reproductive health, and the economic independence of women and girls (with knock-on effects on broader humanitarian and development outcomes).
An increasing challenge to reverse what must be recognized as a protracted and growing gender-based violence (GBV) emergency in the Sahel and the Horn of Africa.
The food insecurity crisis in the Sahel and the Horn of Africa is protracted, multidimensional and highly gendered, with spiralling impacts on gender equality and food security outcomes. It is driven by interwoven and overlapping factors, including climate change, political instability, conflict, socioeconomic conditions, migration and displacement and, more recently, COVID-19 and the war in Ukraine. Interlinked with these factors are gendered structural drivers of food insecurity, including deeply entrenched gender inequalities and harmful social norms. Gendered risks and impacts of food insecurity include alarming limitations on access to education, sexual and reproductive health rights, women’s agency and participation, and dramatic increases in different existing forms of GBV and the emergence of new ones. Recognition of such gendered dimensions of food insecurity and of the need for a multisectoral approach in the response is key to addressing the crisis, along-side sustained commitment and adequate allocation of resources. This policy brief draws out key findings from the OCHA discussion paper on this topic, which includes a desk review of studies, assessments and reports, and interviews with local women’s organizations on the front lines of the food insecurity crisis in communities across both regions.
Below are the most pressing gendered drivers, risks and impacts of food insecurity (not in order of priority), as well as key gaps in the current humanitarian response to food insecurity, and recommendations to take forward.

Interpeace has been working with the government and non-governmental actors in Rwanda for over 20 years, focusing on societal healing and participatory governance. Currently, Interpeace is implementing a holistic peacebuilding programme titled ‘Reinforcing community capacity for social cohesion an...d reconciliation through societal trauma healing in Rwanda’. This programme has four pillars: mental health and support; social cohesion and reconciliation; collaborative livelihoods; and prisoner rehabilitation and reintegration.
Interpeace and its partners have collaborated with national and international experts to design structured psycho-social interventions, scientifically known as ‘protocols’, which aim to support healing and peace processes. These protocols include resilience-oriented therapy, adaptations of sociotherapy, multifamily therapy, the collaborative livelihoods (COLIVE) protocol, the prisoner rehabilitation and reintegration curriculum, and the socio-emotional skills curriculum.
These protocols guide interventions in healing spaces for Genocide survivors, Genocide perpetrators, former combatants, and their descendants. They facilitate mutual healing and reconciliation, strengthen the mental resilience of individuals and communities, promote family cohesion, and address the intergenerational transmission of Genocide legacies. They also underpin initiatives to develop collaborative livelihoods and skills development, and the psychological rehabilitation and reintegration of prisoners, particularly those convicted of Genocide crimes.
