Antimicrobial resistance (AMR) occurs when disease-causing pathogens are able to withstand the killing or suppressing power of antimicrobial medicines. This phenomenon increases the global burden of infectious diseases and strains health systems.This course aims to improve the learner's awareness an...d understanding of the basic principles of AMR, the impact AMR has on individuals and society, and why it is a major public health concern.
A complementary course, Antimicrobial Resistance (Part 2), describes interventions that address the multiple factors contributing to AMR across the health system.

The uneven distribution of HIV risks and burdens across populations is a well-substantiated fact, though seldom publicly acknowledged. Gay men and other men who have sex with men, people who inject drugs, sex workers, and transgender women are 24, 24, 13.5, and 49 times more likely to acquire HIV, ...respectively, than other reproductive aged adults (15 years old and older). Globally, new infections among these key populations account for 45% of all new HIV infections. This figure is likely to be an underestimate, given the intense stigma associated with disclosing and reporting acquisition risks for HIV among gay men, people who use drugs, sex workers, and transgender people. In addition, HIV epidemics in the majority of low- and middle-income countries (90 of 120) have concentrated epidemics among key populations. In countries with more broadly generalized epidemics, risks are still not evenly distributed and key populations still shoulder disease burden that is markedly disproportionate.

Myanmar is one of the world’s 22 high tuberculosis (TB) burden countries, and supporting TB control in Myanmar is a global priority. This report reflects the findings, discussions, conclusions and recommendations of the fourth international review mission of the Myanmar National TB Programme (NTP)..., which brought together international and national partners to review progress in TB control and to offer guidance on future TB control directions and efforts.
A high-quality national disease prevalence survey completed in 2010 demonstrated a TB disease burden two to three times higher than anticipated on the basis of previous surveys. In 2011 about 200 000 adults and children will have developed TB, including 20 000 HIV infected and 9000 suffering from MDR-TB, both of which will require additional care and costly treatment. TB remains among the top killers of adults, and more women die of TB than from maternal causes.

Mental disorders impose an enormous burden on society, accounting for almost one in three years lived with disability globally. •In addition to their health impact, mental disorders cause a significant economic burden due to lost economic output and the link between mental disorders and costly, po...tentially fatal conditions including cancer, cardiovascular disease, diabetes, HIV, and obesity.•80% of the people likely to experience an episode of a mental disorder in their lifetime come from low- and middle-income countries.• Two of the most common forms of mental disorders, anxiety and depression, are prevalent, disabling, and respond to a range of treatments that are safe and effective. Yet, owing to stigma and inadequate funding, these disorders are not being treated in most primary care and community settings.

The prevalence of chronic non-communicable diseases such as diabetes, cardiovascular diseases and cancers has been on the increase in Kenya in the recent past. This has been occasioned by changes in social and demographic situation in the country. The life expectancy... in the country is improving, while the country is developing at a rapid pace. This has resulted in people living more years and at the time adopting lifestyles that have negative impacts on their health. This increase in diabetes and other non-communicable diseases has given rise to a double burden of communicable and non-communicable diseases in Kenya

The harmful use of alcohol causes approximately 3 million deaths every year and the overall burden of disease and injuries attributable to alcohol consumption remains unacceptably high. The pace of development and implementation of alcohol policies has been uneven in WHO regions, and resources and c...apacities for implementation of the WHO Global strategy to reduce the harmful use of alcohol 10 years after its endorsement do not correspond to the magnitude of the problems. On this basis, the WHO Executive Board in its decision EB146 (14) called for accelerated action to reduce the harmful use of alcohol.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimated 239 million people are currently infected, with burden estimated at more than 3.5 million disability...-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

Leishmaniasis is a major vector-borne disease caused by obligate intramacrophage protozoa of the genus Leishmania, and transmitted by the bite of phlebotomine female sand flies of the genera Phlebotomus and Lutzomyia, in the old and new worlds, respectively. Among 20 well-recognized Leishmania speci...es known to infect humans, 18 have zoonotic nature, which include agents of visceral, cutaneous, and mucocutaneous forms of the disease, in both the old and new worlds. Currently, leishmaniasis show a wider geographic distribution and increased global incidence. Environmental, demographic and human behaviors contribute to the changing landscape for zoonotic cutaneous and visceral leishmaniasis. The primary reservoir hosts of Leishmania are sylvatic mammals such as forest rodents, hyraxes and wild canids, and dogs are the most important species among domesticated animals in the epidemiology of this disease. These parasites have two basic life cycle stages: one extracellular stage within the invertebrate host (phlebotomine sand fly), and one intracellular stage within a vertebrate host. Co-infection with HIV intensifies the burden of visceral and cutaneous leishmaniasis by causing severe forms and more difficult to manage. The disease is endemic to Ethiopia, and the clinical signs are not pathognomic. The visceral form (Kala-azar) may be confused with other similar conditions such as malaria, tropical splenomegaly, schistosomiasis, milliary tuberculosis, and brucellosis. Similarly, cutaneous leishmaniasis should be differentiated from disease like tropical ulcers, impetigo and leprosy. There are several methods of laboratory diagnosis of leishmaniasis, including parasitological, immunological and molecular. Different forms of treatments are available including oral, parenteral, and topical medications such as pentavalent antimonials, liposomal amphotericin B, miltefosine and paromomycin. Methods of control are largely limited to destruction of animal reservoirs, treatment of infected humans, and management of sand fly populations. Development of an effective vaccine against leishmaniasis has been largely unsuccessful and hinders its prevention.

Infertility is a disease of the male or female reproductive system defined by the failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse. Understanding the magnitude of infertility is critical for developing appropriate interventions, for monitoring access t...o quality fertility care, and for mitigating risk factors for and consequences of infertility.
The objective of this report is to provide estimates of the global and regional prevalence of infertility by analyzing all relevant and representative studies from 1990 to 2021, taking into account different study approaches. This report also provides insight into how the estimation of infertility prevalence can be improved to obtain more reliable and actionable data. These estimates improve the understanding of the burden of infertility, and provide a basis for appropriate policies and services to achieve universal access to fertility care for all.

Diets are changing everywhere, and the burden of disease associated with unhealthy diets is a worldwide concern. Measurement and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the wor...ld is evolving.
This report assesses the validity, usefulness and fitness for purpose of existing healthy diet metrics as global and national monitoring indicators, presents a comparative assessment of selected healthy diet metrics and discusses priorities and opportunities to improve diet monitoring. This report is an important first step of the Healthy Diets Monitoring Initiative to respond to the need for developing healthy diets metrics for assessing and monitoring diets at national and global level.

I examine the effectiveness of donors in targeting the highest burden of malaria in the Democratic Republic of Congo when health information structure is fragmented. I exploit local variations in the burden of malaria induced by mining activities as well as financial and epidemiological data from he...alth facilities to estimate how local aid is matching local health needs. Using a regression discontinuity design, I find significant but quantitatively small variations in aid to health facilities located within mining areas. Comparing local aid with the additional cost of treatment and prevention associated with the increased risk of malaria transmission, I find suggestive evidence that local populations with the highest burden of the disease receive a proportionately lower share of aid compared to neighbouring areas with reduced exposure to malaria infection. The evidence of disparities in the allocation of aid for malaria supports the view that donors may have inaccurate information about local population needs.

Mental disorders are a leading cause of the global burden of disease, and the provision of mental health services in developing countries remains very limited and far from equitable. Using the Creditor Reporting System, we estimate the amounts and patterns of development assistance for global mental... health (DAMH) between 2007 and 2013. This allows us to examine how well international donors have responded to calls by global mental health advocates to scale up evidence-based services. Although DAMH did increase between 2007 and 2013, it remains low both in absolute terms and as a proportion of total development assistance for health (DAH). The average annual DAMH between 2007 and 2013 was US$133.57 million, and the proportion of DAH attributed to mental health is less than 1%. Approximately 48% of total DAMH was for humanitarian assistance, education, and civil services. More annual DAMH was channelled into the nonpublic sector than the public sector. Despite an expanding body of evidence suggesting that sustainable mental health care can be effectively integrated into existing health systems at relatively low cost, mental health has not received significant development assistance.

In the WHO South-East Asia Region, epidemiological knowledge of mental health conditions remains
a relative unknown, given the sparsity of data and information on (a) the total burden associated
with each disorder; (b) the degree of met and unmet needs for treatment and interventions; and
(c) the... patterns and costs of treatment. This is a common situation in other regions of the world,
where the global descriptive epidemiology of the Global Burden of Disease (GBD) study is mainly
used in association with the WHO Global Health Estimates (GHE) to quantify, at the very least, the
total burden associated with mental health conditions.
