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 ...an class="attribute-to-highlight medbox">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.

Lymphatic filariasis is a neglected tropical disease that can cause permanent disability through disruption of the lymphatic system. This disease is caused by parasitic filarial worms that are transmitted by mosquitos. Mass drug administration (MDA)... of antihelmintics is recommended by WHO to eliminate lymphatic filariasis as a public health problem. This study aims to produce the first geospatial estimates of the global prevalence of lymphatic filariasis infection over time, to quantify progress towards elimination, and to identify geographical variation in distribution of infection.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense... challenge, but the payoff is more effective and sustainable experiences, with higher social awareness, increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

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 replacing 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).

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associa...ted with current serological tests makes it difficult to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

The objective of this concept note and the framework it outlines is the elimination of a group of CDs and ...x">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. Though 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....

This report is the annual global monitoring report documenting progress towards Sustainable Development Goal (SDG) 2 targets 2.1 and 2.2. This year’s report explores the links between urbanization... and changing food systems and how these changes are impacting the availability, affordability and desirability of healthy diets, food security and malnutrition in all its forms. It shows that understanding the ways in which urbanization is shaping food systems will require using a rural-urban continuum lens. By mapping the interlinkages across the rural-urban continuum, governments can identify challenges created by urbanization and suitable policies, technologies, investments and governance mechanisms to help address them.

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during ...o-highlight medbox">the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline is available both online and PDF.
**This version of the living guideline (version 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

This report makes clear that there is a path to end AIDS. Taking that path will help ensure preparedness to address other pandemic challenges, and advance progress across the Sustainable Development Goals. ...>The data and real-world examples in the report make it very clear what that path is. It is not a mystery. It is a choice. Some leaders are already following the path—and succeeding. It is inspiring to note that Botswana, Eswatini, Rwanda, the United Republic of Tanzania and Zimbabwe have already achieved the 95–95–95 targets, and at least 16 other countries (including eight in sub-Saharan Africa) are close to doing so.
