Trachoma is one of oldest infectious diseases known to humans. It is caused by the bacteria Chlamydia trachomatis, which is transmitted through contact with eye secretions of infected people (shared

sed by bacteria, viruses, or other pathogens, NCDs are typically long-lasting and result from a combination of genetic, physiological, environmental, and behavioral factors. NCDs are the leading cause of death worldwide and responsible for over 70% of global deaths each year. Over 80% of these deaths occur in low- and middle-income countries (WHO). Noncommunicable diseases pose a serious threat to global health because they are widespread, costly, largely preventable, and responsible for the majority of deaths worldwide. Reducing their impact requires coordinated efforts in prevention, early detection, and healthcare system strengthening, particularly in lower-income countries. The Toolbox on Noncommunicable Diseases (NCDs) can play a vital role in strengthening Global Healthcare systems by providing centralized, reliable, and up-to-date health information and resources like clinical guidlelines, education material as well as tools for prevention and health promotion.

diseases or multidrug-resistant organisms (MDRO) within their settings and communities. Therefore, evidence-based infection prevention and control (IPC) measures in health care facilities are critical for preventing and containing outbreaks, while still delivering safe, effective and quality health care. This toolkit is intended to support IPC improvements for outbreak management in all such facilities, both public and private throughout the health system. Specifically, this document systematically describes a framework of overarching principles to approach the preparedness, readiness and response outbreak management phases. The document also provides a toolkit of resource links to guide specific actions for each infectious disease and/or MDRO outbreak management phase at any health facility. This document is specifically tailored to an audience of stakeholders who establish and monitor health care facility-level IPC programs including: IPC focal points, epidemiologists, public health experts, outbreak response incident managers, facility-level IPC committee(s), safety and quality leads and managers, and other facility level IPC stakeholders.

Pathogen genomic surveillance has become a priority for public health systems in recent years.

imicrobial resistance (AMR)). The decrease in cost and time of sequencing and the exponential development of bioinformatic pipelines have played a critical role in integrating pathogen genomics into routine public health surveillance. The coronavirus disease 2019 (COVID-19) pandemic has highlighted the role that sequencing plays in the surveillance of infectious diseases. Sequencing facilitates earlier detection, more accurate investigation of outbreaks, closer real-time monitoring of pathogen evolution and tailored development and evaluation of interventions to inform local to global public health decision-making and action. However, there remains a need to coordinate efforts, leverage and link existing surveillance and laboratory networks and capabilities, and systematically integrate genetic sequence data (GSD) with clinical and epidemiological data to strengthen its utility.

s of the age range in low-income and middle-income countries. In children, who represent a large proportion of the total population, the increasing problem of asthma is a strain on health services. Improved survival of the older population is increasing the proportion of morbidity and mortality attributable to chronic lung diseases. Health services in low-resource countries are poorly adapted to treating chronic diseases. Designed to respond episodically to acute disease, almost all historical investment has focused on infectious diseases. Crucial to the successful management of chronic diseases is an infrastructure designed to support pro-active management, providing not only an accurate diagnosis, but also a secure supply of cost effective drugs at an affordable price. The absence of such an infrastructure in many countries and the market failure that makes drugs generally more expensive in low-resource regions means that many people with chronic non-communicable lung diseases are not given effective treatment. This has damaging economic consequences. The common causes of poor lung health in lowincome countries are not the same as those in richer countries, and there is a need to study why they are so common and how best to manage them.

In the “WHO Roadmap for Neglected Tropical Diseases 2021–2030”, leprosy, human African trypanosomiasis (HAT) and onchocerciasis are targeted for interruption of transmission. Acknowledging the growing necessity for establishing a process to verify the absence of new autochthonous leprosy cases, a technical guidance has been developed outlining a clear pathway, demarcating phases with
indicators and milestones leading towards the elimination of leprosy disease.

Planning, preparedness, and practice will protect patients, visitors, and staff.

they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare facilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic.

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and
...
outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.
