Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

The aim of the people-centred framework is to help countries to develop fully prioritized and budgeted NSPs based on a culture of making full use of the available data, which are aligned with national planning cycles and which provide the basis for a robust national response that can accelerate prog...ress towards the goal of ending TB. In addition, applying the framework for other possible applications according to the country’s planning and policy cycle encourages the culture of data utilization and evidence translation into decision making and planning.

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).

These guidelines provide specific recommendations and expert suggestions — for national policy-makers and programme managers and their partners and stakeholders— on prioritizing, planning and providing HIV testing, counselling, treatment and care services for adolescents
Nepal has performed exceptionally in improving reproductive, maternal and child health outcomes over the past two decades. In this article, we discuss these achievements and outline a vision for the future of maternal, newborn and child survival in Nepal after the era of the Millennium Development G...oals. On the pathway towards quality universal health care services for all, we propose strengthening of health information systems, gradual health system reforms, improvement of existing facility based services, development of integrated service delivery models, improved technical and managerial capacity at district and facility levels. Elimination of all preventable causes of maternal, newborn and child deaths in Nepal should be our collective aspirational goal.

UNHCR’s Public Health Strategy 2021-2025 is based on the lessons learnt, and builds on the achievements, of the Global Strategy for Public Health 2014-2018.
Progress was made on policies favouring inclusion and integration into national systems3 with 92% of 48 operations surveyed reporting refuge...es having access to national primary health care facilities under the same conditions as nationals and 96% reporting refugees having access to all relevant vaccines under the same conditions as nationals. While many refugee hosting countries have policies that allow refugees to access national health services, many face partial access, prohibitive out-of-pocket expenditures and other barriers including distance to facilities, language and provider acceptance. Furthermore, more work is needed on strengthening these systems to be able to meet the needs of both host communities and refugees.

Action on behalf of unaccompanied and separated children should be guided by principles enshrined in international standards. The validity of these principles has been confirmed by experience and lessons learnt from conflicts and natural disasters in recent years. The objective of the present public...ation is to outline the guiding principles which form the basis for action in this regard.
