Noma (cancrum oris) is a severe gangrenous disease of the mouth and face. It mostly affects children between the ages of 2 and 6 years living in extreme poverty. In addition to the known factors such as malnutrition, lack of vaccination in children and poor oral hygiene, several social and environme...ntal factors such as maternal malnutrition and close spacing of pregnancies that result in offspring with increasingly weakened immune systems are potentially related to the onset of the disease.
The aim of this guide is to assist the ministries of health (MoHs) to identify a general goal to be attained by the end of five years, with a view to sustainably reducing the incidence of noma as a public health problem through programmes that are fully integrated with national health planning, strengthening of primary health care (PHC) and attainment of UHC.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular diseases, diabetes and chronic respiratory diseases and their risk factors are an increasing public health and development challenge in Turkey. This report provides evidence through three analyses that NCDs reduce economic output, and di...scusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs are equivalent to 3.6% of gross domestic product. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

High salt consumption is an important determinant of high blood pressure and reducing it would improve health outcomes by lowering cardiovascular disease and therefore death rates. Reducing salt intake has been identified as one of the most effective public health measures and is one of the leading ...targets at global, regional and national levels to reduce the burden of noncommunicable diseases. The purpose of the Dietary Salt Intake Survey in the Republic of Moldova was to establish current baseline average consumption of salt (sodium), potassium and iodine through 24-hour urinary excretion testing among a random sample of the adult population (aged 18–69 years), and to assess the knowledge, attitudes, practices and behaviour around dietary salt in order to enable more efficient planning and the implementation of an effective salt-reduction strategy in the Republic of Moldova.

Health communication has proven to play a crucial role in addressing diseases such as dengue, Zika and chikungunya, for which there are no definitive or easily accessible vaccines. In this context, this discipline becomes a fundamental tool to promote the change behavior and promote preventive pract...ices that reduce the transmission of these diseases. By not having a definitive medical solution, accurate and timely information, effectively disseminated through educational campaigns, media and communication channels public health, can significantly influence individual and community actions to control the spread of these mosquito-borne viruses. The accumulated research around the threat of the aforementioned arboviral diseases brings together a series of recommendations around specific communication activities, such as disseminating timely and accurate information that integrates public health concerns and the needs of information of the population, especially vulnerable groups such as women of childbearing age, pregnant women and health workers.

To implement the set of recommendations on the marketing of foods and non-alcoholic beverages to children
With the growing obesity crisis among children, WHO and other public health advocates and consumer groups have called for restrictions on advertising of ‘unhealthy foods’ high in salt, ...sugar and fat to children. Each day, children in the South East Asia Region are exposed to large volume of marketing of unhealthy foods that may influence children’s food preferences and consumption patterns and is associated with childhood overweight and obesity.
The definition of ‘unhealthy’ is debatable, and therefore, an objective method of describing foods as healthy or unhealthy is needed. A nutrient profile model does just that and therefore, a nutrition profile model for South East Asia was developed. The model is consistent with international guidance for preventing chronic disease and is a simple system with clear cut-offs for defining which foods are not suitable for advertising to children.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.
