WHO Guideline. Since 2010, countries in the meningitis belt have started to introduce a new serogroup A meningococcal conjugate vaccine conferring individual protection and herd immunity. Following the successful roll-out of this vaccine, epidemics due to Neisseria meningitidis serogroup A (NmA) are... disappearing, but other serogroups (e.g. NmW, NmX and NmC) still cause epidemics, albeit at a lower frequency and of a smaller size. Due to these changes, WHO organized the review of the evidence to provide recommendations for epidemic control, related to operational thresholds for investigation and response to outbreaks, the use of rapid diagnostic tests, antibiotic regimens in epidemics, and prophylaxis for household contacts of cases

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.

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.

Antimicrobial resistance has become one of the most eminent threats to global health and a rising concern for healthcare specialists. All around the world, many common infections are becoming resistant to the antimicrobial medicines used to treat them, resulting in high morbidity and mortality with ...serious social and economic implications. Additionally, there are few new antibiotics being developed but they are expensive and are not new classes. Antimicrobials are critical in the management of infectious diseases. They are also essential tools for protecting animal health and welfare, and contribute in production of safe food. Inappropriate use of antimicrobials can lead to resistance which is known as the antimicrobial resistance (AMR) resulting in high morbidity and mortality with serious social and economic implications.

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.

Irresponsible pharmaceutical companies fuel the proliferation of superbugs through supply chain pollution, the European Public Health Alliance (EPHA) reports. The advocacy group uncovered lapses such as dirty production and inadequate waste disposal in the production of antimicrobials in China and I...ndia, which supplies most of the antimicrobials consumed in Europe. In a briefing detailing the pollution, the EPHA urges major purchasers of antibiotics to blacklist irresponsible pharmaceutical companies, demand that the industry clean up its supply chain, introduce greater transparency on the origin of antibiotics, and review and revise procurement policies from an ethics perspective.

1st edition.
Unitaid’s report describes a slate of new devices that can more efficiently identify dangerously ill children so that they can be treated immediately. These tools make it easier to recognize danger signs, and support integrated approaches to reducing childhood deaths from the three ...greatest childhood killers: malaria, pneumonia and diarrhoea.
The report also highlights tests that can determine whether or not a child has an illness that can be treated with antibiotics. Viral infections are a common cause of childhood fevers, but cannot be cured with antibiotics. Although many children seeking care at clinics have fever, three-quarters by some estimates, only a small fraction of those have an illness that can be treated with an antimalarial or antibiotic drug

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.

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.

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.

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).

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.
