Reduction of antibiotic consumption will not be sufficient to control antimicrobial resistance because contagion—the spread of resistant strains and resistance genes—seems to be the dominant contributing factor. Im...proving sanitation, increasing access to clean water, and ensuring good governance, as well as increasing public health-care expenditure and better regulating the private health sector are all necessary to reduce global antimicrobial resistance.

Based on the Vulnerability Index developed in this review, an estimated 22.7 million persons in Myanmar, or 44% of the population, were found to have some form of vulnerability related to human development and/or exposure to active conflict/violence. These people experience varying combinations of p...oor housing, lack of education, poor educational attainment, lack of access to safe sanitation and improved drinking water, and direct exposure to conflict.
Shan and Ayeyarwady have the largest populations of vulnerable persons, a function of both their size and relative vulnerability in comparison to other States and Regions. Yangon and Shan show the widest variation in vulnerability across townships (in terms of the number of vulnerable persons and their level of vulnerability), followed by Mandalay, Chin and Rakhine.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

The National Institute for Transforming India (NITI) Aayog has developed the Composite Water Management Index (CWMI) to enable effective water management in Indian states in the face of extreme water stress. The Index and this associated report are expected to: (1) establish a clear baseline and ben...chmark for state-level performance on key water indicators; (2) uncover and explain how states have progressed on water issues over time, including identifying high-performers and under-performers, thereby inculcating a culture of constructive competition among states; and, (3) identify areas for deeper engagement and investment on the part of the states. Eventually, NITI Aayog plans to develop the index into a composite, national-level data management platform for all water resources in India.

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.

Across Zimbabwe, 7 million people in urban and rural areas are in urgent need of humanitarian assistance, compared to 5.5 million in August 2019. Since the launch of the Revised Humanitarian Appeal in August 2019, circumstances for millions of Zimbabweans have worsened. Drought and crop failure, exa...cerbated by macro-economic challenges and austerity measures, have directly affected vulnerable households in both rural and urban communities. Inflation continues to erode purchasing power and affordability of food and other essential goods is a daily challenge. The delivery of health care, clean water and sanitation, and education has been constrained and millions of people are facing challenges to access vital services.

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.

The sub-Saharan African region, carries 90% of the over 250 million cases of schistosomiasis occurring worldwide. In this region, after Nigeria, Tanzania is second country having the highest cases of schistosomiasis and approximately 51.5%0 of the Tanzanian population is either exposed or live in ar...eas with high risk of exposure. The country is endemic to both Schistosoma mansoni and Schistosoma haematobium, these infections are common in communities characterised with limited access to water, sanitation, hygienic practices and health services. Schistosoma mansoni infection is associated with hepatosplenic disease characterised with hepatomegaly, splenomegaly, progressive periportal fibrosis (PPF) which can lead to portal hypertension and its related sequelae, mainly ascites, liver surface irregularities, oesophageal varices and haematemesis. The main consequences of S. haematobium infection are haematuria, dysuria, nutritional deficiencies, urinary bladder lesions, hydronephrosis, urinary bladder squamous cell carcinoma and in children, growth retardation. Preventive chemotherapy using mass drug administration (MDA) of praziquantel targeting primary school aged children is the main strategy for controlling schistosomiasis in Tanzania.

Cholera which disproportionally impacts poor countries and the most vulnerable continues to affect at least 47 countries across the globe, resulting in an estimated 1.3 – 4 million cases, and 21,000 - 143,000 deaths per year worldwide. In Ethiopia, despite major improvements seen in the increasing... access to healthcare, clean water, and improvement in maternal and child health, the country continues to be significantly affected by cholera outbreaks. From 2015 – 2021 for example, several outbreaks of cholera have occurred in multiple parts of the country resulting in over 105,000 cases and thousands of deaths. Some of the risk factors associated with cholera in Ethiopia include inadequate access to clean water, practice of open defecation, poor household and environmental sanitation, unhygienic latrine and weak sanitation practise among communities.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Issue Brief 33: Since 21 June 2023, 57 024 new cholera cases, including 399 new death have been reported worldwide (European Center for Disease Prevention and Control). In total, 25 countries have reported cases since the beginning of 2023. The major underlying causes of potential outbreaks are poor... environmental infastructure, lack of health care services, lack of save water and sanitation as well as increase population movement. Climate change becomes an additional trigger, as extreme climate events like cyclones,floods and droughts reduce access to clean water and create an ideal environment for cholera to thrive. The overall capacity to respond to the multiple outbreaks is obstructed by a global lack of resources.
This issue brief provides an overview of the current outbreaks, treatment guidelines, information material, countries strategies and more.

Human schistosomiasis is caused mainly by 3 schistosome species: Schistosoma haematobium, S. mansoni and S. japonicum. S. guineensis, S. intercalatum and S. mekongi have a highly localized distribution in Central Africa and along the Mekong River in South-East Asia, respectively. Soil-transmitted h...elminthiases (STH) are infections caused by 4 parasite species: Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale and Necator americanus. The 2 latter species are indistinguishable microscopically and are usually reported together as “hookworms”. Schistosomiasis and STH are neglected tropical diseases (NTDs) and are transmitted mainly in areas with poor access to clean water and sanitation. The presence of an intermediate snail host in water is essential to allow Schistosoma to complete their life cycle. Schistosomiasis and STH can cause significant morbidity, including anaemia, nutritional disturbances and, in the case of schistosomiasis, granuloma, organ pathology and cancer, and an increased risk of acquisition of HIV. In women, urogenital schistosomiasis may cause vaginal bleeding, pain during sexual intercourse and nodules in the vulva, now described as female genital schistosomiasis. Groups at risk for STH and schistosomiasis are those in need of micronutrients: preschool-aged children (pre-SAC, 1–4 years of age), school-aged children (SAC, 5–14 years), women of reproductive age (WRA) and, in addition for schistosomiasis adult and entire communities in high-risk areas.

Humanitarian crises exacerbate nutritional risks and often lead to an increase in acute malnutrition. Emergencies include both manmade (conflict) and natural disasters (floods, drought, cyclones, typhoons, earthquakes, volcanic eruptions, etc.). Complex emergencies are combinations of both manmade a...nd natural disasters, often of a protracted nature. Millions of people are affected by humanitarian crises every year. The increasing frequency and scale of emergencies requires nutrition to be addressed in all phases of a response.
Crisis situations, whether acute or protracted, impact on a range of factors that can increase the risk of undernutrition, morbidity, and mortality. They may involve: the large-scale destruction of property and infrastructure; the erosion of livelihood strategies and purchasing power; a breakdown of and reduced access to essential services, including health services, water supply, and sanitation; and the displacement of large numbers of people. Emergencies can also disrupt social systems and the quality of care/feeding practices. Household access to food may be negatively affected and people may find themselves in overcrowded settlements with their families divided. As a result, at the individual level, there is often an increased risk of deteriorating health and nutritional status, resulting in a greater likelihood of death.

n recent decades, a significant improvement in people’s general health conditions has occurred, leading to an increase in life expectancy at birth in most countries in the Region of the Americas. This progress has been the result of both health technology advances – antibiotics, vaccines, and ot...her treatments – and improvements in the conditions in which people live, including increased access to improved drinking water and sanitation, and health services. Nevertheless, progress has slowed in recent years, and achievements have varied among countries and territories, as well as within them. In the journey toward universal health, it is essential to have the ability to monitor and assess progress in terms of the ultimate goal of health systems: improving the health and well-being of populations. To this end, this edition of Health in the Americas analyzes the standardized rate of potentially avoidable premature mortality as an indicator of health system performance, considering both its preventable component through public and intersectoral health interventions, as well as the treatable component, related to the effectiveness of health services, that is, the quality of health care. The analysis of potentially avoidable premature mortality provides a metric for comparing and tracking performance over time.
