South Sudan continues to struggle with a severe health crisis affecting 8.9 million people, primarily in flood- and conflict-affected regions with population movements (displacement and returns), and disease outbreaks. The nation's health system, heavily reliant on international aid, faces staffing ...and resource shortages. Vulnerable groups, including women, children, the elderly, and those with disabilities, have limited healthcare access and face heightened risks of mortality and illness.
The life expectancy at birth (55 years) is among the lowest globally, as mortality rates remain among the highest with neonatal, infant, under-five mortality rates estimated at 39.63, 63.76 and 98.69 deaths per 1000 live births respectively, and a maternal mortality ratio of 1,223 deaths per 100,000 live births. Although some disease specific mortality rates such as TB and AIDS-related mortality have declined, mortality due to malaria and non-communicable diseases have increased over the past five years.
The main causes of morbidity remain communicable diseases; malaria, is the top cause of morbidity (64%) and mortality (45%) among outpatients, followed by pneumonia and diarrhea.20 Several Counties report malaria cases above the threshold perennially especially during the rainy seasons, affecting mainly children under five years. The last malaria indicator survey (2017) estimated malaria prevalence of 32%, 34% and 18% among children under-five, protection of civilian’s sites, and internally displaced persons, respectively.

This report complements the previous poverty analysis studies by presenting a series of poverty maps of Rwanda at cell and sector levels, based on data from EICV4 and the 2012 Population and Housing Census. A poverty map is simply a map that shows the incidence of poverty in different areas of the c...ountry. It allows the viewer to appreciate, at a glance, the geographic dimensions of poverty. Apart from their intrinsic interest, poverty maps may be used to help guide the allocation of resources across local agencies or governmental units, in an effort to better target efforts to reach the poor by pinpointing the small areas of most need.
In 2015, the National Institute of Statistics of Rwanda (NISR) published the Rwanda Poverty Profile Report which provided a detailed portrait of the extent and nature of poverty in the country, while in 2016 a Poverty Trends Analysis Report which complements the Profile study by looking at the trends in poverty between 2010/11 and 2013/14 was also published. Both reports were based on information collected by an integrated household living conditions survey (EICV4) undertaken between October 2013 and September 2014.

The report notes that iodine deficiency is a leading cause of preventable brain damage worldwide. Insufficient iodine during pregnancy and infancy results in neurological and psychological deficits, reducing a child’s IQ by 8 to 10 points. This translates ...into major losses in the cognitive capital of entire nations and thus their socio-economic development.
The report outlines urgent steps to reduce the risk of mental impairment to babies’ growing brains:
• Integrate salt iodization into national plans to support children’s nutrition and brain development in early childhood;
• Align salt iodization and salt reduction agendas;
• Establish surveillance systems to identify unreached populations;
• Strengthen regulatory systems to enforce existing legislation on salt iodization;
• Recognize the growing importance of fortified foods as potential sources of iodized salt.

The Western Pacific Region is the largest and most diverse region in the world, made up of 37 countries and territories in the Pacific, Oceania and parts of Asia, with a population of more than 1.9 billion people stretching over an area from China and Mongolia in the north to New Zealand in the sout...h. In 1999, 22 countries and territories in the Pacific joined together and launched the Pacific Programme to Eliminate Lymphatic Filariasis. Shortly after, the Global Programme to Eliminate Lymphatic Filariasis was launched in 2000. In 2004, 12 countries in the Asia subregion of the Western Pacific Region and Southeast Asian Region joined and developed the Mekong-Plus Strategic Plan for Elimination of Lymphatic Filariasis. Since then, significant efforts have been made by all endemic countries, with annual mass drug administration (MDA) as a principal strategy, through strong partnership with the WHO and other donors and partners. As a result, by the end of 2019, 10 of 22 endemic countries in the region, including 8 of 16 countries in the Pacific and 2 countries in the Asia subregion, achieved WHO validation for elimination of lymphatic filariasis (LF) as a public health problem. All the other countries are either progressing with post-MDA surveillance or accelerating efforts by adoption of the new triple drug therapy strategy and enhancement of MDA campaigns to tackle persistent transmission. Some 85% of the originally endemic implementation units have stopped MDA and the number of people requiring MDA for LF in the Western Pacific Region was reduced by 72% from 2000 to 2018. This paper reviews the progress, key success factors and remaining challenges and indicates the way forward to achieve LF elimination in the Western Pacific Region.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Many vaccines and drugs hold the promise of reducing mortality and morbidity among pregnant women and infants living in low- and middle-income countries (LMICs). However, sufficient information on the safety of drugs and vaccines in pregnant women is rarely available at the time of product licensure... or approval. To account for this, active safety surveillance efforts are needed during the post-licensure and post-approval
phase to assess the safety of drugs and vaccines in pregnant women and their offspring. Pregnancy exposure registries (PER) are used to monitor the safety of vaccines and drugs. PERs are observational studies that systematically collect health information on exposure to medical products such as drugs and vaccines during pregnancy. This review demonstrates that a number of resources presently exist in LMICs that perform active safety surveillance in pregnant populations. These results indicate such systems employ a wide variety of approaches, each with their own set of strengths and challenges, as summarized in the final section of the report.

Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr...evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

Principaux faits
D’après les estimations, 6 à 7 millions de personnes dans le monde sont infectées par Trypanosoma cruzi (T. Cruzi), le parasite responsable de la maladie de Chagas. La plupart de ces personnes vivent en Amérique latine.
La transmission à l’être humain se fait principalem...ent, en Amérique latine, par l’intermédiaire d’un insecte appelé triatome, qui peut être porteur de T. cruzi.
Parmi les autres modes de transmission de la maladie de Chagas, figurent : la transmission orale (par voie alimentaire), la transfusion de sang ou de produits sanguins, la transmission mère-enfant (congénitale), la transplantation d’organes et les accidents de laboratoire.
La maladie de Chagas ne touchait auparavant que des zones rurales de la Région des Amériques, et surtout de l’Amérique latine. Ces dernières décennies, toutefois, les mouvements de population ont fait que la plupart des personnes infectées sont des habitants de zones urbaines (urbanisation) et que la maladie s’est propagée à d’autres continents (où T. cruzi se transmet par des voies non vectorielles).
L’infection à T. cruzi est curable si un traitement est instauré rapidement après l’infection.
Chez les personnes infectées de façon chronique, un traitement antiparasitaire peut éventuellement prévenir ou enrayer la progression de la maladie, et éviter sa transmission, notamment de la mère à l’enfant.
Jusqu’à 30 % des personnes infectées de façon chronique présentent des troubles cardiaques, et jusqu’à 10 % d’entre elles souffrent de troubles digestifs et/ou neurologiques, ce qui peut imposer un traitement particulier.
Les principales méthodes de prévention de la maladie de Chagas en Amérique latine sont la lutte antivectorielle ainsi que d’autres stratégies visant à réduire la transmission vectorielle.
Dans le monde entier, le dépistage sanguin joue un rôle crucial dans la prévention de l’infection par transfusion ou transplantation d’organes.
Il est essentiel de détecter et de traiter l’infection chez les femmes et les filles en âge de procréer, ainsi que de soumettre tout nouveau-né et ses frères et sœurs à un dépistage dans le cas où la mère est infectée et n’a jamais reçu de traitement antiparasitaire.
Certains facteurs socio-économiques et environnementaux influent fortement sur la maladie de Chagas, dont la propagation et les différentes dimensions interdépendantes justifient la nécessité de mettre en œuvre des stratégies de lutte multisectorielles.
Quelques pays ont mis en place la notification et la surveillance des cas aigus et chroniques et des voies de transmission actives, qui sont essentielles à la lutte contre la maladie de Chagas.

The burden of diabetes is high and increasing globally, and in developing economies like India, mainly fueled by the increasing prevalence of overweight/obesity and unhealthy lifestyles. The estimates in 2019 showed that 77 million individuals had diabetes in India, which is expected to rise to over... 134 million by 2045. Approximately 57% of these individuals remain undiagnosed. Type 2 diabetes, which accounts for majority of the cases, can lead to multiorgan complications, broadly divided into microvascular and macrovascular complications. These complications are a significant cause for increased premature morbidity and mortality among individuals with diabetes, leading to reduced life expectancy and financial and other costs of diabetes leading to profound economic burden on the Indian health care system. The risk for diabetes is largely influence by ethnicity, age, obesity and physical inactivity, unhealthy diet, and behavioral habits in addition to genetics and family history. Good control of blood sugar blood pressure and blood lipid levels can prevent and/or delay the onset of diabetes complications. The prevention and management of diabetes and associated complications is a huge challenge in India due to several issues and barriers, including lack of multisectoral approach, surveillance data, awareness regarding diabetes, its risk factors and complications, access to health care settings, access to affordable medicines, etc. Thus, effective health promotion and primary prevention, at both, individual and population levels are the need of the hour to curb the diabetes epidemic and reduce diabetes-related complications in India

The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public health, l...aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

Anaemia is a serious global public health problem that particularly affects young children, menstruating adolescent girls and women, and pregnant and postpartum women. It is a condition in which the number of red blood cells or the haemoglobin concentration within them is lower than normal, affectin...g the blood’s ability to carry oxygen to the body’s tissues.
To reliably monitor the prevalence of anaemia at a population level, it is vital to measure the haemoglobin concentration in an accurate and precise way. In large-scale surveys, however, haemoglobin is most commonly measured using single-drop capillary blood specimens in point-of-care devices. Emerging evidence suggests that the use of single-drop capillary blood can introduce random and/or systematic errors, which may lead to inaccurate estimates, complicating effective anaemia programming.
This technical brief describes the current best practices for haemoglobin measurement, providing guidance to help plan or implement field surveys to assess anaemia at a population level. Continuing work to review emerging evidence is led by members of the WHO-UNICEF Technical Expert Advisory group on nutrition Monitoring (TEAM).
