Chloroquine and hydroxychloroquine are known to potentially cause heart rhythm problems, and these could be exacerbated if treatment is combined with other medicines, such as the antibiotic azithromycin, that have similar effects on the heart.
En los últimos decenios, el estado general de salud de las personas ha mejorado considerablemente, lo que ha llevado a un aumento de la esperanza de vida al nacer en la mayor parte de los países de la Región de las Américas. Este progreso ha sido el resultado tanto de los avances en las tecnolog...ías sanitarias (antibióticos, vacunas y otros tipos de tratamiento) como de las mejoras en las condiciones en que viven las personas, incluido un mayor acceso al agua potable y el saneamiento mejorados, y a servicios de salud. Sin embargo, el progreso ha aminorado en los últimos años, y los logros han variado entre los países y territorios, así como dentro de ellos. En el camino hacia la salud universal, es esencial tener la capacidad para evaluar el progreso y darle seguimiento de acuerdo con el objetivo fundamental de los sistemas de salud, que es mejorar la salud y el bienestar de la población. Con ese fin, en esta edición de Salud en las Américas se analiza la tasa estandarizada de mortalidad prematura potencialmente evitable como indicador del desempeño de los sistemas de salud, teniendo en cuenta tanto el componente prevenible por medio de intervenciones intersectoriales y de salud pública como el componente tratable, relacionado con la efectividad de los servicios de salud, es decir, la calidad de la atención de salud.

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to ...sepsis. A recent systematic review found that data describing antimicrobial resistance were absent for 43% of countries in Africa, and only two countries have national antimicrobial resistance plans. In addition, small studies have identified indiscriminate antibiotic use both in and out of hospital settings in sub-Saharan Africa. The absence of microbiological data and lack of antibiotic stewardship complicate sepsis management and almost certainly worsens outcomes, particularly in low-resource systems. The purpose of this study was to examine the prevalence, etiology, and outcomes of sepsis among a cohort of critically ill patients in a referral hospital of Malawi, with a focus on the prevalence of culture-confirmed bacteremia and urinary tract infections.

Antimicrobial resistance (AMR) is one of the world’s top 10 public health threats. The World Health Organization (WHO) in the African Region, using the Antimicrobial Stewardship assessment tool, has assessed Member States progress on strengthening national capacity need for effective implementatio...n of antimicrobial stewardship interventions to mitigate the threat posed by AMR. The African Region bears the bulk of the global burden of AMR, which drives up health care costs and the increases the economic burden on families and societies. Ultimately, this puts the achievements of modern medicine at risk when infections can no longer be treated with first-line antibiotics. In 2019, the deaths associated with and those directly attributable to bacterial resistance were estimated around 4.95 million and 1.27 million respectively. Left unchecked, deaths from drug resistant infections will surpass the predicted annual death toll of 10 million by 2050.

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.

Antimicrobial resistance (AMR) is impacting our health, economies and development. Up to 5.2 million people may die because of resistant bacterial infections across the Western Pacific Region from 2020-2030. Childbirth, surgery, cancer treatment and other interventions will become impossibly d...angerous if bacterial infections no longer respond to available antibiotics.

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.

Issue Brief 31: Antimicrobial resistance (AMR) can occur when viruses, bacteria, parasites and fungi change over time. There is no longer a response to medicines, and the infection treatment gets really difficult which increases the risk of a disesase spread, which can lead to severe health problems.... AMR is an increasing threat to global public health worldwide that requires cross-sectional and cross-disciplinary action. It is present in every country and is spurred by several human-made factors, including over- and/or inadequate use of antibiotics, poor hygiene and infection prevention control, and excessive usage of antibiotics outside the health care sector e.g. in life stock production.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Buruli ulcer is caused by infection with Mycobacterium ulcerans. The disease is reported in more than 33 countries worldwide, but only about half of these countries regularly report data to WHO; most cases are reported from subregions of West and Central Africa. The mode of transmission is not known....
About half of those affected are children aged under 15 years; there is no gender difference. Diagnosis is based mainly on clinical and epidemiological characteristics. Of the four methods used for laboratory confirmation (microscopy, polymerase chain reaction (PCR), histopathology and culture), PCR is the most rapid and widely used. Other rapid methods for detection of mycolactone in lesions from suspected cases, such as fluorescent thin-layer chromatography, are under evaluation in four countries in Africa.
Research to develop point-of-care tests is in progress. Treatment of Buruli ulcer comprises 8 weeks of combined antibiotics (rifampicin and clarithromycin). Complementary therapies such as wound care, skin graft and prevention of disability are needed in some cases to ensure full recovery.
The target set by the World Health Organization (WHO) for control of Buruli ulcer is for countries to achieve a rate of case confirmation by PCR of at least 70%. All endemic countries have at least one PCR facility to support confirmation of cases. However, most countries in the WHO African Region have not been able to reach the target, and the rate of case confirmation has been declining

Antimicrobial resistance (AMR) is described as a situation when bacteria, viruses, fungi and parasites
change over time and no longer respond to medicines, making infections harder or impossible to treat,
and increasing the risk of disease spread, severe illness and death.1 AMR in recent years has... become
a global priority in public health due to its widespread consequences and increasing occurrence from
time to time. AMR has a formidable impact where the existing antibiotics and other antimicrobial
medicines become ineffective, and infections become increasingly difficult or impossible to treat.

The toolkit provides guidance on where to get started, including the structures and resources that should be put in place at the national and health-care facility level, through a stepwise approach in low-resource settings. As the ultimate goal of an AMS programme is sustainable behaviour change in ...physicians’ antibiotic prescribing practices, the toolkit also provides detailed guidance on how to plan, perform and assess AMS interventions – including feedback on antibiotic use over time. Finally, the toolkit provides an overview of the competencies an AMS team needs to guide health-care professionals in changing their antibiotic prescribing behaviours.

This Study presents the key results of a research that analyses the implications of an ambitious agroecological transition across Europe, following the TYFA scenario. Published in 2018, what it proposes by 2050 is fully aligned with the objectives that the European Farm to Fork and Biodiversity stra...tegies aim to achieve by 2030, in particular regarding the decrease in pesticides, nitrogen, and antibiotics on the supply side, and the transition towards more plant-based diets on the demand side. Using a world biomass balance model (GlobAgri-AgT), the impact of the TYFA scenario in the EU on world land use, the EU physical trade balance, the provision of calories and global food security is analysed in addition to key policy levers to spur the transition.

According to WHO, infection prevention and control (IPC) is a scientific approach and practical solution designed to prevent harm caused by infection to patients and health workers. It is grounded in infectious diseases, epidemiology, social science and health system strengthening. IPC occupies a un...ique position in the field of patient safety and quality universal health coverage since it is relevant to health workers and patients at every single health-care encounter. Poor WASH and IPC lead to health acquired infections, transmission of diseases from health facilities to communities and increased use of antibiotics and exacerbate outbreak and spread of infections- in this case- COVID- 19. On the contrary, effective IPC reduces hospital-acquired infections by at least 30% (WHO 2016).

Antimicrobial resistance (AMR) is a multifaceted, international public health problem, which poses a direct threat to the safety of the population of South Africa. A national response is required to complement the development of a global plan, as articulated in the WHO’s draft resolution EB134/37 ...“Combating antimicrobial resistance including antibiotic resistance”, adopted by theWorld Health Assembly in May 2014. The overuse of antimicrobials is driving resistance. A return to appropriate, targeted antimicrobial use in humans, animals and the environment is critical if we are to conserve the antimicrobial armamentarium. Various interventions have been put in place to address antimicrobial resistance in South Africa. However, these are insufficient to effectively tackle the threat faced by the country. The strengths of the current system are outweighed by its weaknesses.
