This manual has been developed to guide rapid risk assessment of acute public health risks from any type of hazard in response to requests from Member States of the World Health Organization (WHO). The manual is aimed primarily at national departments with health-protection responsibilities, Nationa...l Focal Points (NFPs) for the International Heath Regulations (IHR) and WHO staff. It should also be useful to others who join multidisciplinary risk assessment teams, such as clinicians, field epidemiologists, veterinarians, chemists, food-safety specialists.

In 2007, WHO warned that infectious diseases are emerging and re-emerging at a rate that has not been seen before. The potential for infectious diseases to spread rapidly results in high morbidity and mortality, causing a potential global public health treat of major concern.
Several factors are ...contributing to the (re)emergence of infectious diseases such as population growth, living in close contact with animals, frequent travelling, poverty, destructive ecological changes due to economic development and land use and climate change result in global warming.
Especially Africa is at a threat for (re)emerging infectious diseases due to the huge population growth (expected to reach 2.5 billion by 2050) with rapid urbanisation. Additionally, people across and beyond the continent are excessively mobile which is combined with a weak health system. Moreover, the risk of (re)emerging infectious disease is further heightened by three newly adopted continental initiatives: African Continental Free Trade Area, Free Movement of Persons and African Passport and Single African Air Transport Market.

Antibiotics have been a critical public health tool since the discovery of Penicillin in 1928, saving the lives of millions of people around the world. In developing country like ours, where the burden of treatable disease is very high and access to health facilities and laboratories is difficult, a...ntibiotics have long acted as miracle drugs. Today, however, the emergence of drug
resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and in some cases, nonexistent. Diseases previously regarded as relatively easy to manage are much harder to treat as doctors must use “last-resort” drugs that are more costly, take longer to work
and are often unavailable or unaffordable in developing countries. Moreover, regular prescription of antibiotics, random treatment, over the counter sales, inadequate dosage, inclusion of antibiotics in animal feeds and agriculture has contributed equally to emergence of antibiotics resistance as silent epidemic within the country.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Health care waste can be difficult to treat and dispose of safely. The environmental and health impacts of waste put extra pressure on resources. Therefore, it is important to try and reduce the quantities of waste wherever possible. Ensure waste is segregated properly at the point of disposal. It i...s cheaper and easier to manage general waste through a municipal waste system than infectious or sharps waste which needs treatment before final disposal. Organic general wastes like food and paper can be composted rather than being wasted. Non- hazardous general waste may also be sorted for recycling.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.

Schistosomiasis is a public health problem in tropical and subtropical regions of Africa, Asia, the Caribbean and South America. It is one of the neglected tropical diseases (NTDs) - a group of diseases and conditions that affect particularly low-income populations, worldwide.
Last year, WHO laun...ched a new road map for 2021-2030 that aims to end the suffering from NTDs by 2030, in line with the Sustainable Development Goals. The road map specifically targets the elimination of schistosomiasis as a public health problem, globally.
This guideline provides evidence-based recommendations in the following areas: prevalence thresholds, target age groups and frequency of PC, establishment of WASH and snail control activities to support control and elimination of schistosomiasis, diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs, in snail hosts, and in humans.

There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic climate change. ...This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

Water security, or having the right amount and quality of water in the right place at the right time, fosters social and economic progress. Where water is sufficient to meet demand, it can promote economy wide growth and enable countries to reach their food security, energy security, and human devel...opment goals. Where it is scarce, excessive, or unclean it can exacerbate multiple dimensions of poverty. Neither of these two worlds is protected from future water crises, which are heavily influenced by changing local circumstances

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.

Lessons learned from recent public health events such as the COVID-19 pandemic, Ebola virus disease, Zika virus disease outbreaks, and other public health threats, including earthquakes and floods, have highlighted the need for countries to continuously develop, strengthen, and maintain capacities r...equired under the International Health Regulations (2005) (IHR (2005)).
Developing capacities for health security in a country requires the engagement of public and private entities across a broad range of sectors, including human and animal health, agriculture, environment, finance, security, emergency management, education, and transportation. The World Health Organization (WHO) is mandated through various resolutions, decisions, and reports of the World Health Assembly, and through the IHR (2005), to provide technical guidance and support to its Member States in developing, strengthening, and maintaining their health systems, including capacities required under the IHR (2005).
For countries to better prevent, prepare for, detect, notify, respond to, and recover from public health emergencies, they must build and maintain IHR core capacities and support the strengthening of health emergency prevention, preparedness, response, and resilience (HEPR) capacities. National Action Plans for Health Security (NAPHS), as capacity development plans, provide the tasks and resources needed to ensure adequate capacities are in place to prevent, detect, respond to, and recover from public health events in a sustainable manner. Investing in the resilience of these capacities within national health systems at national and local levels not only improves national health security but also helps safeguard economic, social, and political developments.

The WHO report on health preparedness for El Niño 2015-2016 describes the impact of this weather phenomenon on global public health. Strong El Niño events lead to extreme weather conditions, including droughts, floods, and storms, which increase the risk of diseases such as cholera, malaria, and d...engue fever. Particularly affected regions include Africa, Asia-Pacific, and Latin America, where water and food shortages and disease outbreaks are becoming more frequent.
The WHO supports countries through risk assessments, emergency plans, and disease surveillance to prevent outbreaks. Recommended measures include early warning systems, health preparedness in vulnerable areas, and better coordination between health and meteorological services to minimize the negative effects of El Niño on public health.
