Noma (cancrum oris) is a serious gangrenous disease of the mouth and face, mainly affecting children aged 2 to 6 years in sub-Saharan Africa.
Despite substantial knowledge gaps, it is reported to be linked with malnutrition, poor oral hygiene, immunosuppression, and living in extreme poverty situ...ations.
This course addresses epidemiology, pathogenesis, clinical features, diagnosis, treatment, and public health considerations, including the human rights perspective of noma.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particularly in sub-Saharan Africa.
These guidelines update the recommendations that were first released i...n 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

The CDC's "Malaria's Impact Worldwide" webpage provides an overview of malaria's global burden, highlighting that in 2022, there were approximately 249 million malaria cases and 608,000 deaths, predominantly among young children in sub-Saharan Africa. It emphasizes that nearly half the world's po...pulation is at risk, with malaria being a leading cause of illness and death in many affected countries. The page also discusses the significant economic and social costs of malaria on individuals, families, communities, and nations. Despite progress in reducing mortality rates by 36% from 2010 to 2020, recent years have seen a plateau in advancements, underscoring the need for ongoing vigilance and research.

This Implementation Kit (I-Kit), developed by the Health Communication Capacity Collaborative (HC3), which is funded by USAID and based at the Johns Hopkins Center for Communication Programs, offers structured guidance for improving social and behavioural change communication (SBCC) strategies relat...ed to malaria in pregnancy (MiP). Designed for programme managers and stakeholders, the toolkit addresses critical communication gaps in MiP programming, particularly among service providers. It provides tools to help users integrate MiP into situation analyses, segment audiences, define behavioural objectives and draft strategic communication plans.
MiP poses a significant public health challenge, contributing to maternal and neonatal mortality and morbidity in sub-Saharan Africa. Although effective interventions exist, such as the use of insecticide-treated nets, intermittent preventive treatment in pregnancy (IPTp) and timely diagnosis and treatment, their implementation remains inconsistent. The I-Kit supports more effective SBCC planning and implementation, with the aim of increasing the uptake and impact of these interventions and ultimately reducing malaria-related deaths and illness among pregnant women and newborns.

Malaria in children presents significant clinical challenges, with variations in presentation based on the malaria parasite involved and the child's underlying health conditions. The World Health Organization reports high incidence rates, particularly in sub-Saharan Africa, and emphasizes the import...ance of effective treatment strategies. First-line treatment often involves Artemether-Lumefantrine (ALu), while severe malaria requires careful management and the use of intravenous Quinine. Management protocols emphasize early diagnosis and the monitoring of severe complications to reduce mortality.

his sequel to the Groundswell report includes projections and analysis of internal climate migration for three new regions: East Asia and the Pacific, North Africa, and Eastern Europe and Central Asia. Qualitative analyses of climate-related mobility in countries of the Mashreq and in Small Island D...eveloping States (SIDS) are also provided. This new report builds on the scenario-based modeling approach of the previous Groundswell report from 2018, which covered Sub-Saharan Africa, South Asia, and Latin America. The two reports’ combined findings provide, for the first time, a global picture of the potential scale of internal climate migration across the six regions, allowing for a better understanding of how slow-onset climate change impacts, population dynamics, and development contexts shape mobility trends.

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.

Schistosomiasis is widely recognized as a disease that is socially determined. An
understanding of the social and behavioural factors linked to disease transmission and
control should play a vital role in designing policies and strategies for schistosomiasis
prevention and control. To this must b...e added the awareness that schistosomiasis is
also a disease of poverty. It still survives in poverty-stricken, remote areas where there
is little or no safe water or sanitation, and health care is scarce or non-existent. For
a variety of complex reasons, many of which are addressed in this book, the disease
is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural
China. This concern for human behaviour in an environment of poverty echoes the
concerns of the new research priority for “diseases of poverty” identified by the
Special Programme for Research & Training in Tropical Diseases.

Nearly 800 women die every day from preventable maternal causes, and in 2022 alone, an estimated 2.3 million newborns died. For every maternal death, countless more women endure life-altering injuries, infections, and disabilities related to childbirth.
Maternal deaths are concentrated in the poo...rest regions and conflict-affected areas. In 2020, sub-Saharan Africa accounted for nearly 70% of all maternal deaths, with just 22 countries responsible for 81% of the global total. Humanitarian crises and fragile health systems exacerbate these challenges, with maternal mortality rates in crisis-affected areas often double the global average. The barriers to progress are multifaceted, including inadequate funding, poor-quality healthcare, harmful gender and social norms, and critical gaps in data and accountability.

This year’s MPI results show that more than two-thirds of the multidimensionally poor—886 millionpeople—live in middle-income countries. A further 440 million live in low-income countries. In both groups, data show, simple national averagescan hide enormous inequality inpatterns of povertywith...in countries. For instance, in Uganda 55 percentof the population experience multidimensional poverty—similartotheaverage in Sub-Saharan Africa. But Kampala, the capital city, has an MPI rate of sixpercent, whileinthe Karamojaregion, the MPI soars to 96 percent—meaningthat partsof Ugandaspan the extremes of Sub-Saharan Africa.There is even inequality under the same roof. In South Asia, for example, almost a quarter ofchildren under five live in households where at least one child in the household is malnourished but at least one child is not.
There is also inequality among the poor. Findings of the2019 global MPI paint a detailed picture of the many differences in how-and how deeply -people experience poverty. Deprivationsamong the poor varyenormously: in general, higher MPI valuesgo hand in hand with greater variationin the intensity of poverty. Results also show that children suffer poverty more intensely than adults and are more likely to be deprived in all 10 of the MPI indicators, lackingessentialssuch as clean water, sanitation, adequate nutrition or primary education

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.”

Infections by the soil-transmitted helminths (STH), including Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale/Necator americanus (hookworms), and Strongyloides stercoralis, disproportionately affect children around the world. Because of their transmission associated with poor sanita...ry conditions and inadequate hygiene practices, higher burden of disease is seen in children from developing countries from sub-Saharan Africa, Southeast Asia, and Latin America. Approximately 267 million preschool-age children (PSAC) and 568 million school-age children (SAC) worldwide are at risk of STH infection as well as impaired child growth and cognitive development from A. lumbricoides, T. trichiura, and hookworm infections, and death due to severe S. stercoralis infection. Thus, their control is a global health priority.

Globally, in low-income countries, the average newborn mortality rate is 27 deaths per 1,000 births, the report says. In high-income countries, that rate is 3 deaths per 1,000. Newborns from the riskiest places to give birth are up to 50 times more likely to die than those from the safest places.
...>
The report also notes that 8 of the 10 most dangerous places to be born are in sub-Saharan Africa, where pregnant women are much less likely to receive assistance during delivery due to poverty, conflict and weak institutions. If every country brought its newborn mortality rate down to the high-income average by 2030, 16 million lives could be saved.
More than 80 per cent of newborn deaths are due to prematurity, complications during birth or infections such as pneumonia and sepsis, the report says. These deaths can be prevented with access to well-trained midwives, along with proven solutions like clean water, disinfectants, breastfeeding within the first hour, skin-to-skin contact and good nutrition.
