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.

According to the latest available estimates, more than 1 in 7 adolescents aged 10–19 is estimated to live with a diagnosed mental disorder globally. Almost 46,000 adolescents die from suicide each year, among the top five causes of death for their age group. Meanwhile, wide gaps persist between me...ntal health needs and mental health funding. The report finds that about 2 per cent of government health budgets are allocated to mental health spending globally.

Children in every country, every culture and at every social level face various forms of abuse,
neglect, exploitation and violence1. The abuse takes place at home, in school, in institutions,
at work, in the community, in armed conflict and natural disasters. Much violence against
children, such ...as corporal punishment and sexual abuse, remains legal and socially approved
in many countries. Growing up with violence and abuse seriously affects a child’s development,
dignity, and physical and psychological integrity. Save the Children works to prevent
abuse and neglect from happening, ensure the victims of violence are supported and that
justice is ensured.

An Examination of 13 Projects in PEPFAR-Supported Countries
Malaria is a prevalent cause of febrile illnesses in areas with high transmission, and its clinical presentation overlaps with initial signs of Ebola disease. For this reason, the effectiveness of the Ebola response in Guinea, Liberia and Sierra Leone can be optimized through the deployment of targe...ted measures to reduce the number of fever cases due to malaria
WHO recommends specific adaptations in the diagnosis of malaria and in LLIN distribution in countries heavily affected by the Ebola outbreak and mass drug administration using artemisinin-based combination therapies (ACTs) in areas where transmission of both Ebola and malaria is high and access to malaria treatment is very low.

23rd February 2017, Protea Hotel Thuringerhof, Windhoek | 2017 Namibia ART Guidelines: Summary of New and Old Recommendations
As of 15 May 2020, more than 4 million confirmed cases of COVID-19, including more than 285,000 deaths have been reported to WHO. The risk of severe disease and death has been highest in older people and in persons with underlying noncommunicable diseases (NCDs), such as hypertension, cardiac diseas...e, chronic lung disease and cancer.

A large meta-analysis of observational studies that provided the basis for the recent makeover of global recommendations for multidrug-resistant tuberculosis (MDR-TB) treatment shows that newer and repurposed drugs produced better outcomes and fewer deaths than older treatments.
The meta-analysis... of 50 studies involving 12,000 patients from 25 countries, published yesterday in The Lancet, found that bedaquiline, linezolid, levofloxacin, and moxifloxacin were associated with greater treatment success and reduced mortality compared with the previously recommended first-line treatments, while clofazimine and carbapenem antibiotics were associated with significantly improved treatment outcomes (but not reduced mortality)

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).
