Globally, more people live in urban areas than in rural areas, with 55 % of the world’s population residing in urban areas in 2018. In 1950, 30 % of the world’s population was urban, and by 2050, 68 % of the world’s population is projected to be urban.
Climate change is the single biggest health threat facing humanity, and health professionals worldwide are already responding to the health harms caused by this unfolding crisis.
The Intergovernmental Panel on Climate Change (IPCC) has concluded that to avert catastrophic health impacts and prevent... millions of climate change-related deaths, the world must limit temperature rise to 1.5°C. Past emissions have already made a certain level of global temperature rise and other changes to the climate inevitable. Global heating of even 1.5°C is not considered safe, however; every additional tenth of a degree of warming will take a serious toll on people’s lives and health.

Antimicrobial resistance happens when microorganisms (such as bacteria, fungi, viruses, and parasites) change when they are exposed to antimicrobial drugs (such as antibiotics, antifungals, antivirals, antimalarials, and anthelmintics). Microorganisms that develop antimicrobial resistance are someti...mes referred to as “superbugs”.
As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.

Epidemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world. The background factors of this threat are biological, environmental and lifestyle changes, among others. A potentially fatal combination of newly-discovered ...diseases, and the re-emergence of many long-established ones, demands urgent responses in all countries. Planning and preparation for epidemic prevention and control are essential. The purpose of this “Managing epidemics” manual is to provide expert guidance on those responses.

About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease is
found mainly in endemic areas of 21 Latin American countries. Chagas disease was once entirely
...
confined to rural areas but in the last decades, due to population movements, most infected people live
in urban settings and the disease has spread to other continents. The burden of disease is due to its
chronic progression with people still suffering years later after initial infection.

Snake bite is a neglected public health issue in many tropical and subtropical countries. About 5.4 million snake bites occur each year, resulting in 1.8 to 2.7 million cases of envenomings (poisoning from snake bites). There are between 81 410 and 137 880 deaths and around three times as many amput...ations and other permanent disabilities each year.

Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection occurs when filarial parasites are transmitted to humans through mosquitoes. Infection is usually acquired in childhood causing hidden damage to the lymphatic system.
Soil-transmitted helminth (STH) infections are among the most common infections worldwide with an estimated 1.5 billion infected people or 24% of the world’s population. These infections affect the poorest and most deprived communities with poor access to clean water, sanitation and hygiene in tro...pical and subtropical areas, with the highest prevalence reported from sub-Saharan Africa, China, South America and Asia. They are transmitted by eggs present in human faeces, which in turn contaminate soil in areas where sanitation is poor. Over 260 million preschool-age children, 654 million school-age children,108 million adolescent girls and 138.8 million pregnant and lactating women live in areas where these parasites are intensively transmitted, and are in need of treatment and preventive interventions.

Planning and preparation for epidemic prevention and control are essential. The purpose of the Managing epidemics handbook is to provide expert guidance on those responses. Building on the first edition, the second edition provides concise and basic up-to-date knowledge with which public health officials can respond effectively and rapidly at the very start of an outbreak. Part I of the handbook provides insights on epidemics of the 21st century and offers context on the upsurge of recent epidemics. Part II has been updated and offers 10 key facts about 19 deadly diseases including tips on the interventions required to respond. Part III presents various Tool boxes that summarize guidance on several important topics. The handbook focuses on practical and indispensable things to know about infectious diseases that are most important for national, political and operational decision-makers; it also links readers to more exhaustive WHO guidan

The World Health Organization's Global Health Observatory (GHO) provides comprehensive data on noncommunicable diseases (NCDs), including cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes. The portal offers country-specific statistics on NCD mortality rates, risk factors, ...and national responses, facilitating analysis and comparison across regions. It also includes resources such as publications and tools to support global efforts in NCD prevention and control.

The World Health Organization's fact sheet on noncommunicable diseases (NCDs) highlights that NCDs, such as cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes, are responsible for 74% of all global deaths, totaling 41 million annually. Notably, 86% of premature NCD deaths (...before age 70) occur in low- and middle-income countries. Key risk factors include tobacco use, physical inactivity, harmful alcohol consumption, unhealthy diets, and air pollution. The WHO emphasizes the importance of preventive measures, early detection, and comprehensive healthcare strategies to address the growing NCD burden.

The WHO fact sheet on household air pollution highlights that around 2.1 billion people rely on solid fuels like wood and coal for cooking, using open fires or inefficient stoves. This leads to severe indoor air pollution, contributing to about 3.2 million premature deaths each year, including over ...237,000 children under five. Health impacts include strokes, heart disease, COPD, and lung cancer. Women and children are particularly affected due to their roles in cooking and fuel gathering. WHO calls for the adoption of clean energy solutions, such as electricity and solar power, to mitigate the health risks associated with household air pollution.
