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.

Marco Schäferhoff and colleagues critique funding estimates for the maternal and child health Millennium Development Goals, and make recommendations for improving the tracking of financing flows and estimating the costs of scaling up interventions for mothers and children.
Cervical cancer, along with maternal deaths, has been identified as a national priority in
South Africa as well as other Sub-Saharan African countries. Cervical cancer is the
second most common cancer among women in South Africa, after breast cancer. Due
to limited access to prevention, early dia...gnosis and treatment, cervical cancer is often
fatal.

Prompt, effective antimalarial treatment, and supportive care can substantially reduce the rate of mortality from severe malaria. However, many children in malaria-endemic countries do not have access to health facilities or a qualified health care provider and do not receive the necessary care in a... timely fashion. Without rapid detection of danger signs and access to effective treatment, including pre-referral treatment that can be administered in the community level, many of these children with severe malaria die.
In situations where there is no immediate access to a health care facility, WHO recommends the administration of a standard dose of an effective antimalarial medicine as pre-referral treatment before referral to a facility at which complete treatment can be administered.
Rectal artesunate is the WHO-recommended pre-referral intervention in situations where artesunate injection are not feasible for children under the age of 6 years with suspected severe malaria. The intervention reduces the risk of death or permanent disability by up to 50% provided the child is referred to a health facility at which complete treatment can be administered.
This field guide is aimed at supporting the effective deployment of RAS as pre-referral treatment of suspected severe malaria in line with the WHO malaria guidelines.

The World Health Organization (WHO) is releasing the second edition of its Global Accelerated Action for the Health of Adolescents (AA-HA!) guidance. The document aims to equip governments to respond to the health and well-being challenges, opportunities and needs of adolescents.
The guidance pro...vides the latest available data on adolescent health and well-being. It also outlines an updated list of core indicators that data should be collected on. Globally, road injury was the top cause of death for adolescent males in 2019. Among female adolescents, the leading causes of death were diarrhoeal diseases among the younger group (10-14 years) and tuberculosis (TB) in the older group (15-19 years).
Over the last 20 years, mortality rates have declined among adolescents globally, with the largest decline in older (15–19 years) adolescent girls. For non-fatal diseases, the burden has not improved over the past two decades, with the main causes of ill health in this category being: mental health conditions (depressive and anxiety disorders, childhood behavioural disorders), iron deficiency anaemia, skin diseases and migraine.
Adolescent well-being depends on a range of factors, including healthy food, education, life skills and employability, connectedness, feeling valued by society, safe and supportive environments, resilience, and the freedom to make choices. To take an appropriately holistic approach, the guidance outlines how to take crosscutting action to support adolescent health and well-being, with mutually reinforcing interventions across sectors, such as health, education, social protection, and telecommunications. Targeted efforts are also required to engage adolescents, as they trust health systems less than adults do and are especially vulnerable to modern-day trends, like online bullying and gaming.

While there has been real progress in addressing the burden of disease in the WHO African region, the COVID-19 pandemic has highlighted the link between health, economics and security, as the region saw decades of progress threatened, including positive trends in decreasing inequality. In the Africa...n Region the momentum towards achieving the 2030 SDG disease burden reduction targets (SDG targets 3.3, 3.4 and 3B) has stalled.
The COVID-19 pandemic was also a major threat to gains made, such as the eradication of polio in the region, declared in 2020; reduced numbers of new HIV infections in 2021 compared to 2010; and passing the 2020 milestone of the End TB Strategy, with a 22% reduction in new cases compared with 2015. However, the pandemic also disrupted essential health services in 92% of countries globally, 22.7 million children missed basic immunization, there was an increase in malaria and TB, and global deaths from TB rose for the first time since 2015.

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline... is available both online and PDF.
**This version of the living guideline (version 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

Multi-sectoral Cholera Elimination Plan
This resource pack was developed for the country offices of the World Health Organization and national Public Health institutions, as an overview of the key information needed for advising their Member States in response to questions raised on human health due to influenza outbreaks or detections in... animals. It assembles the available information from WHO, FAO and WOAH, on recommendations and guidelines on influenza that might be relevant to a country experiencing detections or outbreaks of influenza in animals or facing suspicion of human infections with animal-origin influenza viruses. This resource pack updates the information provided in the Summary of Key Information Practical to Countries Experiencing Outbreaks of A(H5N1) and Other Subtypes of Avian Influenza, published in 2016. Additionally, the scope of this current document was broadened to address the risks to public health from all animal influenza viruses, not only avian influenza. Links to existing resources were updated and new resources were added where available.

The WHO COVID-19 Clinical management: living guidance contains the most up-to-date recommendations for the clinical management of people with COVID-19. Providing guidance that is comprehensive and holistic for the optimal care of COVID-19 patients throughout their entire illness is important.
This report makes clear that there is a path to end AIDS. Taking that path will help ensure preparedness to address other pandemic challenges, and advance progress across the Sustainable Development Goals. The data and real-world examples in the report make it very clear what that path is. It is not... a mystery. It is a choice. Some leaders are already following the path—and succeeding. It is inspiring to note that Botswana, Eswatini, Rwanda, the United Republic of Tanzania and Zimbabwe have already achieved the 95–95–95 targets, and at least 16 other countries (including eight in sub-Saharan Africa) are close to doing so.

A lot has happened this year. While we continued to tackle the COVID-19 pandemic, we were hit by disease outbreaks and
humanitarian crises. Yet, despite these challenges, we marched on, resolute in resolving critical health systems issues to increase
access to quality healthcare services. To furth...er our vision and bring concrete actions to reality, under
the leadership of the Government of South Sudan, we developed the Health Sector Strategic Plan to define the strategic
approaches, key interventions, mapping resource needs, and the implementation framework to strengthen the health system
to deliver essential quality health services equitably for 2023 to 2027. For WHO, this Plan will usher in a new reality -- access
to lifesaving or health-promoting interventions is doable and possible, making the health sector fairer, especially for those
unable to pay

Las infecciones del sitio quirúrgico (ISQ) constituyen una de las Infecciones Asociadas al Cuidado de la Salud (IACS) más frecuentes que ponen en riesgo a los pacientes llevando muchas veces al fracaso del procedimiento quirúrgico. Con una incidencia mucho mayor en países de medianos y bajos ing...resos, representa un desafío de la práctica médica cotidiana que compromete la salud y la seguridad de los pacientes. La indicación de profilaxis primaria con antibióticos en relación a los procedimientos invasivos, tiene como objetivo disminuir la incidencia de infecciones con la consecuente disminución de la morbimortalidad debiendo utilizarse únicamente en aquellos procedimientos en los que hay evidencia de efectividad. Cabe destacar que la indicación inadecuada, tiene potenciales efectos adversos tales como infecciones por Clostridium difficile, emergencia de resistencia
bacteriana, reacciones adversas a drogas e incremento de los costos en salud.
La profilaxis antibiótica como complemento de una buena técnica quirúrgica, es una medida costo efectiva de prevención de las ISQ representando alrededor del 30% de la indicación de antibióticos entre los pacientes hospitalizados. Dado que en algunos estudios el uso inapropiado de antibióticos se ve reflejado en el 40 al
80% de las indicaciones médicas, desde la Comisión de Infecciones Asociadas al Cuidado de la Salud y Seguridad del Paciente de SADI hemos realizado una actualización de la evidencia disponible. Este documento es una acción complementaria al consenso “Prevención de Infección del Sitio Quirúrgico” realizado entre SADI y el Instituto Nacional de Epidemiología “J. Jara” durante el Congreso de SADI 2015.
La posibilidad de contar con una guía actualizada de profilaxis quirúrgica adaptada a nuestro medio, constituye una herramienta de uso cotidiano por parte de los profesionales del equipo quirúrgico que permite la optimización de la utilización de fármacos restringiendo así la emergencia y diseminación de la resistencia bacteriana. Sin duda esperamos que pueda ser de utilidad para el equipo de salud.

Globally each year, millions of people suffer illness or lose their lives because the vaccines, medicines and diagnostic tests that they need are either unavailable or unaffordable – and this lack of access to medicine is acute in low- and middle-in-
come countries (LMICs). While the COVID-19 pan...demic laid this inequity bare, it also saw the pharmaceutical industry develop and bring new vaccines and treat- ments to market at unprecedented speed. As the world emerges from the worst
of this crisis, pharmaceutical companies are now at an important juncture, where lessons learned from the pandemic can prove pivotal in finding solutions to bridge long-standing gaps in access to medicine in LMICs.
