Las infecciones de transmisión sexual (ITS) constituyen un importante problema de salud pública en todo el mundo, que afecta a la calidad de vida y se acompaña de importantes niveles de morbilidad y mortalidad. Estas infecciones influyen directamente en la salud infantil y reproductiva porque tra...en consigo infertilidad, cánceres y complicaciones del embarazo. También tienen una influencia indirecta porque facilitan la transmisión por vía sexual del virus de la inmunodeficiencia humana (VIH), pesando así igualmente en la economía de los países y las personas. Cada día, más de un millón de personas contraen una infección de transmisión sexual. Se calcula que en 2012 hubo en el mundo 357 millones de nuevos casos de ITS curables (blenorragia, clamidiasis, sífilis o tricomoniasis) que afectaron a adultos de entre 15 y 49 años de edad, entre ellos 5,6 millones de casos de sífilis. El número de casos prevalentes de sífilis asciende, según las estimaciones, a unos 18 millones.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

There has been important progress for the rights of adolescent girls and women in recent decades, yet millions still struggle to
access the nutritious diets, essential nutrition services and nutrition and care practices they need to prevent malnutrition.
Undernutrition, micronutrient deficiencies ...and anaemia amplify gender inequalities by lowering learning potential, wages and life opportunities for adolescent girls and women, weakening their immunity to infections, and increasing their risk of lifethreatening complications during pregnancy and childbirth.

Lack of trained providers capable of identifying which labouring women could benefit from assisted vaginal birth (AVB), and of safely performing the procedure is a major barrier for its use. Education and training are, therefore, considered crucial for building skills and confidence in conducting AV...B and there is evidence that it would be welcomed by healthcare providers. However, acquiring and maintaining AVB skills is a complex task that requires a supportive environment, mentorship, supervision and accountability. As with other practices to manage infrequent procedures and complications, continuous education and on-site supervision are essential to ensure the safe and sustainable use of AVB.

Chronic manifestations of Chagas disease present as disabling and life-threatening conditions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mechanisms underlying Trypanosoma cruzi’s infection and the host-parasit...e interactions that follow, prompt diagnosis and treatment remain a challenge, particularly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence
factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

To support the achievement of health equity in the Region, the regional inter-agency movement Every Woman Every Child Latin America and the Caribbean (EWEC-LAC) advocates for and supports the use of equity and evidence-based policies, strategies and interventions to accelerate equitable progress in ...the health of women, children and adolescents. Although progress has been made, great inequities persist. Women from the LAC region’s poorest countries are almost four times more likely to die due to complications during childbirth than those living in the wealthiest countries. Through the years, several tools, instruments and methods (TIMs) have been developed by global, regional and country partners that can be used to conduct systematic equity-based analyses and/or re-designs of health systems, programs, strategies and interventions. The main purpose of this document is to present an overview of existing TIMs that can be used by policymakers, program managers, development partners, nongovernmental organizations, academia and civil society partners to strengthen systematic identification, analysis and responding to social inequities in the health of women, children and adolescents in LAC. The TIMs included were identified through a systematic search process

WHO today released its first roadmap to tackle postpartum haemorrhage (PPH) – defined as excessive bleeding after childbirth - which affects millions of women annually and is the world’s leading cause of maternal deaths.
Despite being preventable and treatable, PPH results in around 70 000 de...aths every year. For those who survive, it can cause disabilities and psychological trauma that last for years.
“Severe bleeding in childbirth is one of the most common causes of maternal mortality, yet it is highly preventable and treatable,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This new roadmap charts a path forward to a world in which more women have a safe birth and a healthy future with their families.”
The Roadmap aims to help countries address stark differences in survival outcomes from PPH, which reflect major inequities in access to essential health services. Over 85% of deaths from PPH happen in sub-Saharan Africa and South Asia. Risk factors include anaemia, placental abnormalities, and other complications in pregnancy such as infections and pre-eclampsia.
Many risk factors can be managed if there is quality antenatal care, including access to ultrasound, alongside effective monitoring in the hours after birth. If bleeding starts, it also needs to be detected and treated extremely quickly. Too often, however, health facilities lack necessary healthcare workers or resources, including lifesaving commodities such as oxytocin, tranexamic acid or blood for transfusions.
“Addressing postpartum haemorrhage needs a multipronged approach focusing on both prevention and response - preventing risk factors and providing immediate access to treatments when needed - alongside broader efforts to strengthen women’s rights,” said Dr Pascale Allotey, WHO Director for Sexual and Reproductive Health and HRP, the UN’s special programme on research development and training in human reproduction. “Every woman, no matter where she lives, should have access to timely, high quality maternity care, with trained health workers, essential equipment and shelves stocked with appropriate and effective commodities – this is crucial for treating postpartum bleeding and reducing maternal deaths.”

WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT) in the treatmen...t of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.

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.

Around the world, more than 2 billion people lack access to safely managed water, sanitation and hygiene services, with conflicts and climate change exacerbating the issue.
Unsafe and insufficient WASH facilities, especially in rural and remote areas, can lead to increased health complications fo...r older people, persons with disabilities and children. They also reinforce cycles of poverty, inequality and deprivation – particularly for women, children and marginalized groups, who are disproportionately impacted by a lack of equitable access to water and sanitation.
Launched on World Water Day, the guidelines address the knowledge gap on ways to practically implement inclusive approaches to WASH infrastructure development, particularly in developing countries and fragile contexts.

The Global Leprosy Strategy 2021–2030 “Towards zero leprosy” was developed through a broad consultative process with all major stakeholders during 2019 and 2020. Valuable inputs were provided by national leprosy programme managers, technical agencies, public health and leprosy experts, funding... agencies and persons or members of communities directly affected by leprosy.
The Strategy aims to contribute to achieving the Sustainable Development Goals. It is structured along four pillars:
(i) implement integrated, country-owned zero leprosy road maps in all endemic countries;
(ii) scale up leprosy prevention alongside integrated active case detection;
(iii) manage leprosy and its complications and prevent new disability; and
(iv) combat stigma and ensure human rights are respected. Interruption of transmission and elimination of disease are at the core of the Strategy.

Human strongyloidiasis is a chronic parasitic disease caused by infection with Strongyloides stercoralis, a soil-transmitted helminth that is estimated to infect 300–600 million people worldwide. This neglected tropical disease (NTD) is endemic globally, predominately in the South-East Asia, Afric...an and Western Pacific regions, and in South and Central America. Strongyloidiasis has a wide range of clinical presentations, including subclinical disease, symptomatic disease (often with diarrhoea, abdominal pain and urticaria) and a rare but deadly complication of hyperinfection with disseminated disease. The feared complication of disseminated strongyloidiasis can occur in the setting of immunocompromising conditions (e.g. human T-cell lymphotropic virus type 1 infection and malignancies) or immunosuppressive medications (e.g. steroids) and has an estimated case-fatality rate exceeding 60%. The standard treatment for chronic S. stercoralis infection is oral medication with ivermectin.
