Guide pour augmenter la couverture et l'équité dans toutes les communautés de la Région africaine (2017)
Les programmes élargis de vaccination (PEV) sont responsables des vaccins et luttent contre les maladies évitables par la vaccination, dans le but de les éliminer, voire les éradique...r. La présence de systèmes de vaccination solides, aptes à apporter des vaccins à ceux qui en ont le plus besoin, jouera un rôle important dans la réalisation des objectifs de santé et d'équité aussi bien que des objectifs économiques de plusieurs buts de développement mondial. Ces buts comprennent les objectifs de développement durable (ODD) à l'horizon 2030, la Décennie de la vaccination (2011-2020), le programme pour réaliser la couverture universelle d'ici à 2030, le Plan d'action mondial pour les vaccins (2011-2020), les Stratégies et pratiques mondiales de vaccination systématique et le Plan stratégique régional pour la vaccination 2014-2020.

The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and ...its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels.

Level of stunting among Bangladeshi children <5years declined from 51% in 2004 to 36% and underweight from 41% in 2007 to 33% (BDHS 2014). But the decrease in wasting rate is not as expected, which is only from 17% to 14.3 % over last decade. Approximately 3.1 % (BDHS 2014) of under-5 children suffe...ring from SAM only by weight-for-length or height z-score (WHZ) <-3 criterion and estimated to be a total of ~ 450,000. Because, there are no national information on prevalence of SAM using mid upper arm circumference (MUAC) and presence of bipedal oedema in under-5 children, thus the actual number of children suffering from SAM could be much higher than the current estimate.

This operational guidance on MHPSS provides a practical orientation and tools for UNHCR country operations. It covers specific points of good practice to consider when developing MHPSS programming and offers advice on priority issues and practical difficulties, while also providing some background i...nformation and definitions. Since MHPSS is a cross cutting concept this operational guidance is relevant for programming in various sectors, including health, community based protection, education, shelter, nutrition, food security and livelihoods.
The focus of this operational guidance is on refugees and asylum seekers, but it may apply to other persons of concern within UNHCR operations such as stateless persons, internally displaced persons and returnees. The guidance is meant for operations in both camp and non-camp settings, and in both rural and urban settings in low and middle-income countries with a UNHCR presence.
The guidance should be adapted according to different contexts. A standardized format for programme implementation cannot be offered because this depends to a large extent on existing national capacities and local opportunities.

Eleven (11) districts in Rwanda were initially were considered most at risk of the outbreak, namely:
• Rusizi, Nyamasheke, Karongi, Rutsiro, Rubavu (bordering DRC)
• Musanze, Burera, Gicumbi and Nyagatare (bordering Uganda)
• Kigali city (comprised of 3 localities) due to the presence of Ki...gali International Airport.
The National Contingency plan was revised in February 2019 and two districts added to the list (Nyabihu and Nyanza), bring total districts at risk to 13. During the timeframe, the operation, however covered the 11 initial districts.

En 2016, l’ONUSIDA lançait un appel pour que les pays d’Afrique de l’Ouest et du Centre accélérent la riposte au sida. En effet, si dans des pays d’Afrique de l’Est et du Sud les avancées sont réelles, ceux de l’Afrique de l’Ouest et du Centre sont encore en retard dans l’accès... au dépistage et au traitement antirétroviral. Le 3 juillet 2017, les Présidents de l’Union Africaine avaient adopté un plan de rattrapage pour l’Afrique de l’Ouest et du Centre avec l’appui de ONUSIDA, dans le but d’inverser la tendance de l’épidémie et combler les gaps financiers et programmatiques pour l’atteinte des 90-90-90 en 2020. Le Sénégal, à l’instar des pays de la sous région, s’est engagé à élaborer et mettre en œuvre son plan de rattrapage en 2018 pour accélérer les interventions vers l’atteinte de cet objectif. Le plan de rattrapage du Sénégal est lancé officiellement en janvier 2018 au Novotel en présence des autorités, des acteurs et des partenaires.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

Five months after the beginning of the desert locust upsurge in the Greater Horn of Africa and Yemen, and four months since the launch of the response plan (24 January 2020) a total of USD 130 million have been mobilized in the region.
As described in the recently published Food and Agriculture Org...anization of the United Nations (FAO) quarterly report (January to April 2020), a lot has been achieved already, thanks to generous contributions from resource partners and affected governments.
But bringing a desert locust upsurge under control and mitigating its impact on livelihoods and food security requires a prolonged effort and numerous factors could influence the duration and magnitude of the problem, including the widespread presence of COVID-19.

A Technical Brief for Breakthrough ACTION Field Teams
Social media can be used to collect and address rumors or popular beliefs among target audiences, share evidence-based and timely health information, receive instant feedback on materials, conduct remote trainings, promote awareness of a project..., its mission and events, and more. As increased numbers of people search online for health information, social media platforms are leading the lightning-speed spread of both dangerous coronavirus misinformation and the correct life-saving measures individuals, families, and communities can take to reduce their risk. Public health programs must have a proactive presence in these information-sharing spaces to provide access to trusted and accurate information.

The World Health Organization (WHO) has identified mental health as an integral component of the COVID-19 response. Its rapid assessment of service delivery for mental, neurological and substance use (MNS) disorders during the COVID-19 pandemic, on which this report is based, is the first attempt to... measure the impact of the pandemic on such services at a global level. The data were collected through a web-based survey completed by mental health focal points at ministries of health between June and August 2020. The questionnaire covered the existence and funding of mental health and psychosocial support (MHPSS) plans, the presence and composition of MHPSS coordination platforms, the degree of continuation and causes of disruption of different MNS services, the approaches used to overcome these disruptions, and surveillance mechanisms and research on MNS data.

Many determinants are known to affect brain health at different stages of life. The position paper provides a conceptual framework for what brain health is and how brain health can be optimized throughout life with actions across the following clusters of determinants: physical health, healthy envir...onments, safety and security, learning and social connection, and access to quality services. Optimizing brain health can not only reduces the prevalence and burden of neurological disorders, but also improve mental and physical health overall and create positive social and economic impacts, all of which contribute to greater well-being and help advance society, irrespective of the presence or absence of disorders.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

Schistosomiasis is a prevalent parasitic, neglected tropical disease (NTD) affecting over 220 million people globally, especially in sub-Saharan Africa (SSA). The pathology of this disease in terms of intestinal, liver and urinary presentations is well-known, yet its chronic effect on host genitalia... is often ignored or overlooked. Male genital schistosomiasis (MGS) is a gender-specific manifestation of urogenital schistosomiasis (UGS), associated with the presence of Schistosoma haematobium eggs and related pathologies in genitalia of men inhabiting or visiting endemic areas in SSA. Despite the first reported by Madden, the epidemiology, diagnostic testing and case management of MGS are not well-described owing to limited research and diminishing focus over several decades.

HIV-1 infection disproportionately affects women in sub-Saharan Africa, where areas of high HIV-1 prevalence and Schistosoma haematobium endemicity largely overlap. Female genital schistosomiasis (FGS), caused most frequently by S. haematobium egg deposition in the genital tract, has been associated... with prevalent HIV-1 infection in cross-sectional studies. The presence of S. haematobium eggs in genital tissue is also associated with vascularization and the accumulation of CD4+ lymphocytes and macrophages, making the granuloma-associated environment a potential contributor to HIV-1 vulnerability. In addition to modulation of the local cervicovaginal environment, FGS has also been associated with a higher frequency of systemic CD4 T-cells expressing the chemokine receptor CCR5. Tissue-entrapped eggs are also associated with clinically visible FGS-associated manifestations in the cervicovaginal mucosa. FGS lesions may breach the intact cervicovaginal immune barrier and are hypothesized to provide an entry point for HIV-1 infection. However, the underlying mechanism for potential HIV-1 vulnerability in FGS has not been fully characterized and requires further investigation.
