Antibiotics, also known as antimicrobial drugs, are medicines that can kill or inhibit the growth of bacteria to cure infections in people, animals and sometimes plants. Antibiotics are medicines for bacterial infections (such as pneumococcal pneumonia or staphylococcal bloodstream infections); anti...microbial drugs that are effective against viruses are usually called antiviral drugs (such as those for influenza, HIV and herpes). Not all antibiotics are active against all bacteria. There are more than 15 different classes of antibiotics that differ in their chemical structure and their action against bacteria. An antibiotic may be effective against only one or multiple types of bacteria.

Antimicrobials have been a critical public health tool since the discovery of penicillin in 1928, saving the lives of millions of people around the world. Today, however, the emergence of drug resistance is reversing the miracles of the past eighty years, with drug choices for the treatment of many ...infections becoming increasingly limited, expensive, and, in some cases, non-existent.
Conscious of the public health threats of AMR to both humans, animals and the environment, the ministries of health and sanitation, agriculture forestry and food security and the environmental protection agency put together a national multi-sectoral coordinating group tasked with the responsibility of establishing mechanisms to integrate all initiatives into a single concerted action and development of the national AMR strategic plan (2018-2022). The National Strategic Plan on Antimicrobial Resistance is the first approach which addresses AMR specifically.

Of the 50 antibiotics in the pipeline, 32 target WHO priority pathogens but the majority have only limited benefits when compared to existing antibiotics. Two of these are active against the multi-drug resistant Gram-negative bacteria, which are spreading rapidly and require urgent solutions.
Gr...am-negative bacteria, such as Klebsiella pneumoniae and Escherichia coli, can cause severe and often deadly infections that pose a particular threat for people with weak or not yet fully developed immune systems, including newborns, ageing populations, people undergoing surgery and cancer treatment.
The report highlights a worrying gap in activity against the highly resistant NDM-1 (New Delhi metallo-beta-lactamase 1), with only three antibiotics in the pipeline. NDM-1 makes bacteria resistant to a broad range of antibiotics, including those from the carbapenem family, which today are the last line of defence against antibiotic-resistant bacterial infections.

Revised working paper following AVAREF meeting February 2019.
WHO has published a roadmap aiming to coordinate partners’ actions and contributions to the licensing and roll-out of Merck’s Ebola vaccine (VSV-ZEBOV) in African countries. The vaccine was developed during the West Africa Ebola epi...demic of 2014-2016, during which more than 11 000 people lost their lives to the disease. The vaccine was tested in European and African countries at the time and is currently used under an “expanded access” protocol in the Democratic Republic of Congo.
WHO will expedite prequalification and licensing of the vaccine for use in countries at risk of Ebola outbreaks and will coordinate work between those countries’ regulatory authorities and the European Medicines Agency and the US Food and Drug Administration.

Human African Trypanosomiasis (HAT, sleeping sickness) and Animal African Trypanosomiasis (AAT) are neglected tropical diseases generally caused by the same etiological agent, Trypanosoma brucei. Despite important advances in the reduction or disappearance of HAT cases, AAT represents a risky reserv...oir of the infections. There is a strong need to control AAT, as is claimed by the European Commission in a recent document on the reservation of antimicrobials for human use. Control of AAT is considered part of the One Health approach established by the FAO program against African Trypanosomiasis. Under the umbrella of the One Health concepts, in this work, by analyzing the pharmacological properties of the therapeutic options against Trypanosoma brucei spp., we underline the need for clearer and more defined guidelines in the employment of drugs designed for HAT and AAT. Essential requirements are addressed to meet the challenge of drug use and drug resistance development. This approach shall avoid inter-species cross-resistance phenomena and retain drugs therapeutic activity.

This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospita...ls in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included.

Spread of resistance to antimicrobial agents (AMR) does not know national borders and has reached dimensions, which require immediate actions at the national, regional and global levels.
Antibiotic resistance is a natural biological response to improper use of antimicrobial agents (AMA); increasing... number of essential drugs, which become ineffective, contributing to selection, survival and replication of resistant strains of microorganisms. When chosen antimicrobials prove to be ineffective, the second- or third-line drugs need to be used although
in the majority of cases these drugs are more expensive, less safe and not always available.

For 50 patients requiring surgical care in emergency situations assuming 2 operations per patient (100 interventions)
WHO trauma and emergency surgery kit (TESK) aims to provide materials and drugs to meet the needs of 50 patients requiring surgical care in emergency situations, assuming an avera...ge of two operations per patient. This kit is intended for use by health care providers who are trained in appropriate management of emergent surgical issues and are acting within their scope of practise. It is designed for use in areas where basic levels of infrastructure exist. The composition of TESK has recently been revised in collaboration with the International Committee of the Red Cross to meet the dynamic requirements of emergency situations. In general, this kit contains oral and IV medicines including cold chain drugs and medical supplies including renewables and instruments.
WHO TESK is intended to provide the resources needed for surgical procedures in operating theatres. Some of the sub-units may be used for simpler procedures that may occur in other parts of the facility.

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021–2030 (“the road map”) sets explicit targets for the elimination of onchocerciasis by 2030, including eliminating the need for mass drug administration (MDA) of ivermectin in at least... one focus in 34 countries, in more than 50% of the population in at least 16 countries, and in the entire endemic population in at least 12 countries. The road map also targets interruption of onchocercal transmission in 12 countries by 2030. Achieving these targets and milestones will require a number of critical actions. These include establishing a well-coordinated global partnership to connect stakeholders and existing partnerships at all levels in order to improve coordination and collaboration, accelerate technical progress, implement a harmonized research agenda and enhance service delivery.

Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass drug administration (MDA), in each form...erly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in WHO’s African Region.

The Global status report on alcohol and health and treatment of substance use disorders presents a comprehensive overview of alcohol consumption, alcohol-related harm and policy responses as well as treatment capacities for alcohol and drug use disorders worldwide. The report is based on data collec...ted by WHO from Member States and organized in accordance with the Sustainable Development Goals health target 3.5 which calls on countries to strengthen “the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol”. The chapter on alcohol and health continues the series of WHO global status reports on alcohol and health and presents the latest available data on the status of, and trends in, alcohol consumption, as well as estimates of the alcohol-attributable disease burden and descriptions of policy responses worldwide. On the basis of data collected from countries on the treatment of substance use disorders the report describes the status of key components of treatment responses to alcohol and drug use disorders and proposes a new service capacity index for these disorders as an additional contextual indicator for monitoring progress in this domain of SDG health target 3.5. The report concludes with broad directions for international action to accelerate progress towards achievement of SDG health target 3.5.

This document outlines the concept and content of the WHO people-centred approach to addressing antimicrobial resistance (AMR) in the human health sector. The proposed approach recognizes and aims to address the challenges and health system barriers people face when accessing health services to prev...ent, diagnose and treat (drug-resistant) infections. It puts people and their needs at the centre of the AMR response and guides policy-makers in taking programmatic and comprehensive actions to mitigate AMR in line with a proposed package of core interventions. These interventions are based on a review of four pillars and two foundational steps that are critical to overcome barriers faced by people and health systems in addressing AMR.

The Sustainable Development Goals (SDGs) aim to transform our world. They are a call to action to end poverty and inequality, protect the planet, and ensure that all people enjoy health, justice and prosperity. It is critical that no one is left behind. In 2015, all the countries in the United... Nations adopted the 2030 Agenda for Sustainable Development. It sets out 17 Goals, which include 169 targets. These wide-ranging and ambitious Goals interconnect. SDG 3 is to ensure healthy lives and promote well-being for all at all ages. It has 13 targets measured through 26 indicators. However, a person’s health and well-being are affected not only by disease and treatment, but also by social and economic factors such as housing, poverty and education. Health targets can therefore also be found across the other SDGs. This fact sheet shows how alcohol consumption undermines commitments to achieve 13 of the 17 SDGs, impacting on a range of health-related indicators, such as child health, infectious diseases and road injuries as well as much broader range of indicators related to economic and social development, environment and equality. The inclusion of a specific target on harmful use of alcohol (SDG 3.5: strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol) into the SDGs demonstrates the key role of alcohol within the global development agenda. The factsheet highlights positive examples of Member States’ experiences. It provides a short overview of the most cost-effective and feasible policy recommendations to reduce alcohol consumption and alcohol-attributable burden in the WHO European Region, in line with the European Action Plan to Reduce the Harmful Use of Alcohol. It also suggests some important resources for Member States. This factsheet was launched as part of the European Awareness Week on Alcohol Related Harm 2020.

The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.
