High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

Hypertension is the number one health related risk factor in India, with the largest contribution to burden of disease and mortality. It contributes to an estimated 1.6 million deaths, due to ischemic heart disease and stroke, out of a total of about 10 million deaths annually in India. Fifty seven ...percent of deaths related to stroke and 24% of deaths related to coronary heart disease are related to hypertension. Hypertension is one of the commonest non-communicable diseases in India, with an overall prevalence of 29.8% among the adult population, and a higher prevalence in urban areas (33.8% vs. 27.6%)
according to recent estimates.
Awareness of hypertension in India is low while appropriate treatment and control among those with hypertension is even lower: Hypertension is a chronic, persistent, largely asymptomatic disease. A majority of the patients with hypertension in India are unaware of their condition. This is because of low levels of awareness and the lack of screening for hypertension in adults-either as a systematic programme or as an opportunistic exercise during visits to healthcare providers.

Overuse of antimicrobial agents occurs globally in both community and hospital settings. Misuse of antibiotics can lead to a variety of adverse outcomes, including the development of antimicrobial resistanceand increased cost of hospitalization. This issuehas been particularly problematic in de...veloping countries, where antibiotic-management programs rarely exist and where antibiotics can be purchased without aprescription. In Thailand, the rate of antibiotic resistance among gram-positive and gram-negative or-ganisms has increased significantly over the past decade. These findings provide compelling evidence ofthe need for more-rational use of antimicrobial agents in Thailand.

Tuberculosis (TB) control in the African Region has evolved since the disease was declared a global emergency by the World Health Organization (WHO) in 1993. Member States have adopted and implemented successive global and regional strategies and resolutions, with demonstrable positive impacts on in...cidence, prevalence and mortality, albeit with variations across countries. By the end of 2015, the Region as a whole met the key Millennium Development Goal (MDG) target of halting and beginning to reverse TB incidence. However only 35 of the 47 Member States met the MDG target.

These guidelines are based on the 3rd Edition of the WHO Guidelines (Published 2015) World Health Organization’s Guidelines for the treatment of malaria. Additional literature surveys have been undertaken. Factors that were considered in the choice of therapeutic options included effectiveness, sa...fety, and impact on malaria transmission and on the emergence and spread of antimalarial drug resistance. On-going surveillance is critical given the spread of artemisinin resistance in Southeast Asia, although not yet confirmed anywhere in Africa. The guidelines on the treatment of malaria in South Africa aim to facilitate effective, appropriate and timeous treatment of malaria, thereby reducing the burden of this disease in our communities. This is essential to further reduce the malaria case fatality rates currently recorded in South Africa, to decrease malaria transmission and to limit resistance to antimalarial drugs.

Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

The environment in which young people live, learn and play significantly affects their decisions about whether to consume alcohol. Environmental factors are the main risk factors driving alcohol consumption and related harm among young people. Environments that normalize alcohol consumption – term...ed alcogenic environments – include contexts with unregulated advertising and marketing of alcoholic beverages, higher alcohol outlet density, products designed to facilitate affordability and low prices of alcoholic beverages. A recent body of research evidence has emerged related to the measurement, functional significance and consequences of living in alcogenic environments. This includes findings on the complex and bidirectional interactions among alcohol acceptability, availability and affordability and how they create and perpetuate alcogenic environments. Comprehensive and enforced alcohol control policies are effective at delaying the age of onset and lowering alcohol prevalence and frequency among young people. Evidence consistently confirms the effectiveness of designing and implementing alcohol control policies that regulate upstream the drivers of alcogenic environment, including alcohol availability, acceptability and affordability. These policies need to be multipronged and address the complex interactions between these drivers and the local alcohol culture

To describe the behavior of Tuberculosis/Human Immunodeficiency Virus co-infection in a cohort of people affected by sensitive Tuberculosis in Ecuador from 01 January 2010 to 31 December 2015. Results: The percentage of co...infected persons reached 11% in the whole period of study, with a range from 8.4% to 12.7%. Male sex shows the highest incidence rate, representing 76.7% at the rate of 1 man for every 3.3 women. The population with the highest incidence of patients is economically active; the age group of 25-34 years reaches 40.1%. The coastal zone of the country reports more than 75% of the coinfected patients. Conclusion: Increased HIV/AIDS screening should be increased for Tuberculosis, with particular emphasis on male sex and enhance the actions in the coastal provinces.

The National Strategic Plan on Malaria Prevention and Elimination Period 2021 – 2025 seeks to build on the previous national successes of the National Institute of Malariology, Parasitology, and Entomology (NIMPE) while addressing current challenges to reduce the overall burden of malaria in the S...outhern and Central provinces and to initiate elimination activities in remaining focal areas of transmission throughout the country. The overall targets proposed to be reached by 2025 are:
Reduce malaria morbidity rate to below 0.015/1,000 population
Reduce malaria mortality rate to below 0.002/100,000 population
Eliminate malaria in 55 provinces
Ensure no malaria outbreaks
To address the urgent threat of drug resistance, Viet Nam has committed to accelerate efforts to eliminate locally-acquired P. falciparum by 2023.

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Climate change presents significant challenges to human health and biodiversity. Increased numbers of extreme climate events, such as heat waves, droughts or flooding, threaten human health and well-being, both directly and indirectly, through impaired ecosystem functioning and reduced ecosystem ser...vices. In addition, the prevalence of non-communicable diseases is rising, causing ill health and accelerating costs to the health sector. Nature-based solutions, such as the provision and management of biodiversity, can facilitate human health and well-being, and mitigate the negative effects of climate change.

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

Asthma is the most common chronic condition in children worldwide. It affects daytime activities, sleep and school attendance and causes anxiety to parents, families and other carers. The quality of asthma diagnosis and management globally still needs substantial improvement. From infancy to the tee...nage years, there are age-specific challenges, including both underdiagnosis and overdiagnosis with stigma-related barriers to treatment in some cultures and in adolescents. The Paediatric Asthma Project Plan has been initiated to strengthen diagnosis and management of asthma. This encompasses a vision for the next 10–15 years, building on the knowledge and experience from previous educational projects. It will take into account the educational needs of patients, carers and healthcare professionals as well as the accessibility and affordability of medication, particularly in low and middle-income countries where the prevalence of asthma is rising more rapidly. This overview presents a first step for those involved in the diagnosis and management of childhood asthma to strengthen care for children globally.

Schistosomiasis is a public health problem in tropical and subtropical regions of Africa, Asia, the Caribbean and South America. It is one of the neglected tropical diseases (NTDs) - a group of diseases and conditions that affect particularly low-income populations, worldwide.
Last year, WHO laun...ched a new road map for 2021-2030 that aims to end the suffering from NTDs by 2030, in line with the Sustainable Development Goals. The road map specifically targets the elimination of schistosomiasis as a public health problem, globally.
This guideline provides evidence-based recommendations in the following areas: prevalence thresholds, target age groups and frequency of PC, establishment of WASH and snail control activities to support control and elimination of schistosomiasis, diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs, in snail hosts, and in humans.
