There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra...nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

It is estimated that, in Latin America alone, between 6 and 8 million people are infected with the parasite, and 99% of these are not receiving treatment, either because they are unaware of their infection or because they do not know that treatment exists. The potential spread of the disease is also... a cause for considerable concern: 65 million people live in areas of exposure and are at risk of contracting Chagas disease, and 28,000 new cases occur every year.

Prevention, early diagnosis, and effective treatment are essential for the control and elimination of Neisseria gonorrhoeae as a public health problem. Currently, in Latin America and the Caribbean, treatment for gonorrhea infection is largely empiric and based on clinical diagnosis. In the Americas..., the high burden of new N. gonorrhoeae infections (estimated at 11 million new cases a year), the complexity of the disease epidemiology, and in many countries the limited resources, make it difficult to fully understand the burden of disease and the burden of antimicrobial resistance (AMR) in N. gonorrhoeae.
PAHO has developed this document to facilitate the navigation of available guidance and recommendations for N. gonorrhoeae AMR surveillance by public health and health care professionals, at the national and subnational levels, involved in designing, implementing, and/or strengthening AMR surveillance of N. gonorrhoeae and overall surveillance of sexually transmitted infections.

Ramped-up cancer services could save 7 million lives over the next decade—and addressing huge service gaps between rich and poor countries is key to success, according to this report.
In 2019, over 90% of high-income countries reported that comprehensive cancer treatment services were available... through the public health system, compared to fewer than 15% of low-income countries, according to WHO.
But poorer countries can make substantial strides with a universal health coverage approach and use of the latest science to meet their particular needs.
The report lays out proven ways to prevent new cancer cases without breaking the bank, including tobacco-control measures and vaccines that protect against common cancers.

Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the na...tional demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0.8% of the population) and a 3.4% incidence of cryptococcosis in hospitals, it is estimated that 459 patients per year develop cryptococcosis. For pneumocystosis, it is suggested that 1013 new cases occur every year. Taking into account the local TB frequency (population prevalence at 0.052%), we estimate the prevalence of chronic pulmonary aspergillosis at 1120 cases. Severe forms of asthma with fungal sensitization and allergic bronchopulmonary aspergillosis are estimated to affect 7429 and 5628 cases, respectively. Vulvovaginal candidiasis may affect 179,000 women, and almost 1,000,000 children may suffer from tinea capitis. Globally, we estimate that roughly 1.4 million people in Burkina Faso (7.51% of the population) suffer from a serious fungal infection. These data should be used to drive future epidemiological studies, diagnostic approaches, and therapeutic strategies.

Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. I...n 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030.

Specific measures are being taken within the National Tuberculosis Control Programme (NTP) to address the MDR TB problem through appropriate management of patients and strategies to prevent the propagation and dissemination of MDR TB.
The term "Programmatic Management of Drug Resistant TB" (PMD...T) refers to programme based MDR TB diagnosis, management and treatment. This guideline promotes full integration of basic TB control and PMDT activities under the NTP, so that patients with TB are evaluated for drug resistance and are placed on the appropriate treatment regimen and properly managed from the outset of treatment, or as early as possible. The guidelines also integrate the identification and treatment of more severe forms of drug resistance, such as extensively drug resistant TB (XDR TB).
At the end, the guideline introduces new standards for registering, monitoring and reporting outcomes of multidrug resistant TB cases.

On 13 August 2024, Africa Centres for Disease Control and Prevention (Africa CDC) declared the ongoing Mpox outbreak a Public Health Emergency of Continental Security (PHECS). This was followed the next day by the World Health Organization (WHO), which extended the alert internationally as a public ...health emergency of international concern (PHEIC). After these declarations, many countries have made efforts to mobilize resources to introduce or expand laboratory testing, surveillance, and response activities. In particular, as the number of suspected cases surges in the Democratic Republic of Congo (DRC), Burundi, and the Central African Republic, and an increasing number of new countries report cases, there is an urgent need to implement testing to strengthen the Mpox response. However, access to appropriate quality assured diagnostics is a challenge. There is limited information on important characteristics, such as available test kits’ performance and ability to detect relevant clades.
To address the challenge of mpox access in the continent, the Africa CDC Diagnostic Advisory Committee (DAC) met in Kigali from 19-23 August 2024 to review the available evidence on molecular tests for Mpox and to shortlist tests that may be useful for Mpox testing in countries. The shortlist aims to provide guidance to Africa CDC, countries and partners on appropriate high-quality molecular tests to procure and use for the mpox response.

Situation analysis
Description of the disaster
An Ebola epidemic that started in March 2014 in Guinea has relentlessly continued to claim lives and to spread to other countries in West Africa. The current Ebola outbreak is the largest in history and the first to affect multiple countries simu...ltaneously. There have been over 24 000 reported confirmed, probable, and suspected cases of EVD in Guinea, Liberia and Sierra Leone (table 1), with almost 10 000 reported deaths (outcomes for many cases are unknown). A total of 58 new confirmed cases were reported in Guinea, 0 in Liberia, and 58 in Sierra Leone in the 7 days to 8 March (4 days to 5 March for Liberia). Many experts believe that the official numbers substantially understate the size of the outbreak because of families' widespread reluctance to report cases. Because of the fluidity of movement of people between West Africa and several countries in the East African countries, especially Kenya and Ethiopia (who in turn have extensive interaction with other countries in the region in terms of human movement), the risk of an outbreak of Ebola in East Africa is as eminent as in any of the countries bordering the affected countries. The IFRC regional office intends to support National Societies to raise their Ebola preparedness and response capacity through training, technical support in planning and implementation of Ebola related activities, and coordination both within and outside the movement.

In the Region of the Americas, as of 24 February 2023 (16:00 EST), there are a total of 58,578 confirmed cases of mpox (Table 1, Figure 2) were reported from 31 countries and territories, including 76 deaths in: United States of America (34), Brazil (15), Peru (15), Mexico (4), Chile (2), Ecuador (3...), Argentina (2), and Cuba (1), reported from 31 (Table 1, Annex 1, Figure 3). In the last 4 weeks (28 January – 24 February 2023), 607 additional mpox cases were reported from 16 countries and territories, including 9 deaths in Ecuador (1) and United States (8). Eight countries in the Region account for 97% of confirmed cases: United States of America, Brazil, Colombia, Mexico, Peru, Canada, Chile, and Argentina – listed by total number of cases in decrease order (Figure 4). The number of new weekly reported cases in EW 7 compared to EW 6 of 2023 (% variation) decreased by 55%.

WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandem...ic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors.
Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved.
The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.

Leishmaniasis is still considered to be a global health problem, which spreads in most countries in the world. Leishmania is an intracellular obligate protistan parasite that causes different clinical symptoms in infected humans and other animals. There are clinically different types of the disease ...including: visceral, cutaneous or muco-cutaneous leishmaniasis. Approximately, two million new infections occurring annually; 0.7 to 1.2 million cases are recorded with cutaneous leishmaniasis and 200,000–400,000 cases return for visceral leishmaniasis. However, Cutaneous leishmaniasis considers one of uncontrolled wobbling endemic diseases, especially in Iraq, which occurs at the skin to cause a dermal lesion. Usually, the lesion is spontaneously healed to leave a colorless depressed scar and permanent immunity.

Human African trypanosomiasis (HAT) is a lethal neglected tropical disease (NTD) transmitted by the bite of infected tsetse flies. The disease is also known as “sleeping sickness”. During the 20th century it caused enormous suffering in the endemic areas in sub-Saharan Africa. HAT transmission l...ast soared in the late 1990s, triggering a renewed, coordinated and very successful control effort. In this paper, we present achievements towards HAT elimination, with a focus on the WHO road map targets for 2020. In particular, reported cases continue to decline, from over 30,000 cases per year at the turn of the century to 663 cases in 2020. Despite the impact of the COVID-19 pandemic, HAT surveillance was largely sustained, and the network of health facilities able to diagnose and treat the disease further expanded. Looking to the future, the World Health Organization (WHO) set bold new targets for HAT in its 2021–2030 road map for NTDs, namely: the elimination of transmission of gambiense HAT, which occurs in western and central Africa, and the elimination as a public health problem of rhodesiense HAT, which is found in eastern and southern Africa. The strong commitment of national health authorities and the international community will be essential if these goals are to be achieved.

In January 2018, over 10,000 people fled their homes following clashes reported in multiple locations in Jonglei, including Yuai, Pultruk, Payai, Kuer-nyuon, Pieri, Waat and Walgak. Some crossed to
Ethiopia, where 2,300 people registered as refugees in the Gambela region. There were several report...s of people returning from displacement camps and refugee settlements in Uganda to locations in
Central Equatoria, including Lainya, Kajo-keji, Morobo and Yei, as well as reports of movement from Sudan to Bentiu, Unity. However, partners are working to verify these reports; population movements
remain difficult to track and patterns hard to discern. About 5.1 million people were estimated to be severely food insecure between January and March 2018, including 20,000 who are facing catastrophic conditions. According to assessments conducted in January in the Baggari area, Wau County, malnutrition has improved compared to the same period last year, with surveys showing GAM rates of
about 2.8 per cent in Mboro and 3.6 per cent in Farajallah. Last year, Baggari was among locations which surpassed the WHO emergency threshold of 15 percent of the population malnourished. In
January, there were no new reports of cholera cases in South Sudan, marking a continued decline in the outbreak that was declared in June 2016.

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.
