Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated th...at at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The objective of this concept note and the framework it outlines is the elimination of a group of CDs and the negative health effects they generate, which together create a tangible burden on affected individuals, their families and communities, and on health care systems throughout the Region. Thou...gh there is no unified consensus on the best measures to use for the public’s health and a nation’s epidemiologic situation, it is common for the disease burden to be measured by disease rates (incidence, prevalence, etc.), disease-specific death rates, comparative morbidity and mortality rates, geographic distribution, and disability-adjusted life years (DALYs). The current epidemiological situation, including data on disease rates or geographic distribution for the diseases in Table 1, is discussed below in Section 4. Hotez et al. (2008) were the first to review and compare the burden of DALYs in Latin America and the Caribbean—for NTDs, HIV/AIDS, malaria, and TB—as it existed about 10 years ago. Though the regional burden of TB, malaria, and neglected infectious diseases (NIDs) is somewhat less than it was 10 years ago, work (and schooling) continue to be lost to illness and premature death or disability, and the need for stepping up disease elimination efforts is evident in all communities living in vulnerable conditions....

J Glob Health Sci. 2020 Jun;2(1):e3. A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-...ended list of some 20 parasitic, bacterial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.

Language influences the way we think, how we perceive reality, and how we behave. With respect to HIV, language can embody stigma and discrimination, which impacts access to testing, acquisition of HIV, and engagement with treatment. Language plays a role in supporting respect and empowerment of ind...ividuals, as communities shape how they are referred to and the labels they wish to use. Consideration and use of appropriate language can strengthen the global response to the HIV pandemic by diminishing stigma and discrimination and increasing support and understanding for individuals and communities living with HIV.

La lutte contre la tuberculose est une des priorités du ministère de la santé. C’est ainsi que le Plan Stratégique National de lutte contre la Tuberculose 2013-2017 du Sénégal a inscrit dans son programme d’actions la préoccupation de mieux d’améliorer la prise en charge des personnes ...vulnérables, dont les prisonniers. L’état de santé est un indicateur clef du bien être de la société, et les prisons servent de miroir. Une bonne compréhension des conditions sanitaires des détenus pourrait contribuer à améliorer le système de santé publique d’un pays. L’environnement carcéral est bien reconnu comme un lieu où les conditions de vie sont propices à la concentration de l’ensemble des maladies de la société, en premier lieu, les morbidités infectieuses.

La prise en charge de la tuberculose représente un véritable défi en milieu carcéral et l’organisation de la continuité des soins à la sortie un enjeu majeur. Comme tout être humain, les détenus ont le droit de jouir du meilleur état de santé physique et mental possible. Ce droit est gar...anti par l’article 25 de la Déclaration universelle des droits de l’homme adoptée par l’Organisation des Nations Unies, et par l’article 12 du Pacte international relatif aux droits économiques, sociaux et culturels. Ce travail fait un état des lieux sur la prise en charge de la tuberculose en milieu carcéral au Sénégal, depuis les stratégies de dépistage jusqu’à la continuité des soins après la sortie de prison.

22 April 2022, This document provides updated interim recommendations on the use of masks by health workers providing care to patients with suspected or confirmed COVID-19. This update is prompted by new evidence around mask use and COVID-19 transmission, as well as the emergence of variants of conc...ern including Omicron. Masks continue to be a critical tool to prevent the spread of COVID-19. These interim guidelines supersede the recommendations provided in the WHO recommendations on mask use by health workers, in light of the Omicron variant of concern published on 22 December 2022.
WHO continually evaluates the emerging evidence and will review these interim recommendations within two months and issue new guidance as needed.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.
