Leishmaniasis is a vector-borne tropical/subtropical disease caused by an intracellular parasite transmitted to humans by sand fly bite. It is endemic in Asia, Africa, the Americas, and the Mediterranean region. Worldwide reports include 1.5–2 million new cases each year, more than 300 million at ...risk of acquiring the disease, and 70,000 deaths per year. Clinical features depend on the Leishmania species and immune response of the host, varying from localized cutaneous disease to visceral form with potentially fatal outcome; however, the common presentation is either cutaneous, mucocutaneous, or visceral leishmaniasis. Many therapeutic agents are being used in Leishmania treatment, but the only effective treatment is achieved with current pentavalent antimonials. WHO considers Leishmaniasis as one of the “Neglected Tropical Diseases” that continues to be prevalent despite international, national, and local efforts towards its control and elimination over the last decade. This chapter reviews the global perspective of Leishmaniasis with increasing recognition of emerging “Atypical forms” and new surge of disease across the world mainly due to increasing conflicts in endemic areas leading to forced migration among other causes. All these challenges related to environment, disease, and vector pose major implications on WHO’s leishmaniasis control and elimination plan.

Leishmaniasis is a parasitic disease caused by the Leishmania parasite. This parasite typically lives in infected sand flies. You can contract leishmaniasis from a bite of an infected sand fly.
The sand flies that carry the parasite typically reside in tropical and subtropical environments. Fatal... epidemics have occurred in areas of Asia, East Africa, and South America.
Affected regions are often remote and unstable, with limited resources for treating this disease. Doctors Without Borders calls leishmaniasis one of the most dangerous neglected tropical diseases. The organization also states this disease is second only to malaria in parasitic causes of death.

Cutaneous leishmaniasis (CL) is a parasitic disease caused by infection with a vector-borne protozoan parasite of the genus Leishmania spp. The parasite is transmitted by the bite of an infected phlebotomine sand fly. Infection results in skin lesions which take a long time to heal and may leave per...manent, disfiguring scars (de Vries et al. 2015). CL is classified as a neglected tropical disease (NTD), and in common with several other NTDs, is associated with psychosocial effects including stigma, social exclusion, and declining mental health (Bailey et al. 2019; Bennis et al. 2018; Wenning et al. 2022). Emerging evidence suggests that people with CL are at a higher risk of experiencing anxiety, depression, decreased body satisfaction, loss of social status, and lower quality of life (Bennis et al. 2018; Yanik et al. 2004). The global mean age-standardised disability-adjusted life years (DALYs) lost by CL was 0.58 per 100,000 people (Karimkhani et al. 2016). Notably, this statistic only considers the physical effects of the lesions and does not account for the potentially considerable psychological and social effects of CL (Bailey et al. 2017; Bailey et al. 2019; Wenning et al. 2022).

Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of infected sand flies. There are several different forms of leishmaniasis in people. The most com...mon forms are cutaneous leishmaniasis, which causes skin sores, and visceral leishmaniasis, which affects several internal organs (usually spleen, liver, and bone marrow).

This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. Storage tanks are required for collection of water from springs or water produced from continuous flow water... treatment systems, e.g. from upflow clarifiers or slow sand filters. There should be sufficient storage volume to store all water produced overnight, as this is unlikely to be collected by users during the night. Storage tanks also have secondary functions such as ensuring a constant water supply to treatment processes, providing a level of treatment by settlement of larger suspended solids and maintaining pressure in distribution systems

The document titled "Prevención y control del cólera" (Cholera Prevention and Control) provides essential guidance on preventing and managing cholera, a disease characterized by severe watery diarrhea and vomiting. Without prompt treatment, cholera can lead to death due to dehydration within hours.... The disease is primarily transmitted through the ingestion of food or water contaminated with the feces of an infected person.
To protect against cholera and other diarrheal diseases, the document emphasizes the importance of drinking safe water, such as bottled water with intact seals, boiled water, or water treated with chlorine products. Frequent handwashing with safe water and soap is recommended, and in the absence of soap, hands can be cleaned using ash or sand followed by rinsing with safe water. Proper sanitation practices, such as using latrines or burying feces and avoiding defecation near water sources, are crucial. The document also highlights safe food practices, including thoroughly cooking food (especially seafood), consuming it while hot, keeping it covered, and peeling fruits and vegetables. Ensuring the safe cleaning of kitchens and areas where the family bathes or washes clothes is also advised.
In case of diarrheal illness, the document stresses the immediate use of oral rehydration solution (ORS) to prevent dehydration and the importance of seeking medical attention as quickly as possible. Patients should continue ORS intake both at home and during transit to a health facility. These preventative measures and prompt treatment strategies are vital for reducing cholera transmission and mortality.

Despite the significant role of vector control in national leishmaniasis control programmes, the programmatic community perceives vector control as the weakest component of leishmaniasis control strategies in terms of resources, scientific evidence of the usefulness of interventions and capacity for... quality-assured implementation. Therefore, the main objective of this manual is to provide practical tools, techniques and procedures to strengthen sand fly control and surveillance in order to improve implementation of leishmaniasis control programmes. The manual provides a rationale for programme managers in different geographical regions on the types of vector control interventions to be used in different epidemiological and environmental settings and also how to measure their impact.

Indoor residual spraying (IRS) involves applying residual insecticide to potential vector resting sites on the interior surfaces of human dwellings or other buildings. The main aim of IRS is to kill vectors before they are able to transmit pathogens to humans. When carried out correctly, IRS has his...torically been shown to be a powerful intervention to reduce adult vector density and longevity for mosquitoes, sand flies and triatomine bugs and can reduce the transmission of vector-borne diseases.

This toolkit for integrated vector management (IVM) is designed to help national and regional programme managers coordinate across sectors to design and run large IVM programmes.
The toolkit provides the technical detail required to plan, implement, monitor and evaluate an IVM approach. IVM can... be used when the aim is to control or eliminate vector-borne diseases and can also contribute to insecticide resistance management. This toolkit provides information on where vector-borne diseases are endemic and what interventions should be used, presenting case studies on IVM as well as relevant guidance documents for reference.
The diseases that are the focus of this toolkit are malaria, lymphatic filariasis, dengue, leishmaniasis, onchocerciasis, human African trypanosomiasis and schistosomiasis. It also includes information on other viral diseases (Rift Valley fever, West Nile fever, Chikungunya, yellow fever) and trachoma. If other vector-borne diseases appear in a country or area, vector control with an IVM approach should be adopted, as per national priorities.

People-centered approaches that help communities maintain protective behaviours and follow guidelines set out by public health and government agencies are more important than ever. The evidence is clear, communities play a role in preventing and controlling epidemics and they are best able to take a...ction and slow or stop the spread of disease when properly engaged and empowered. This toolbox in 2 parts offers best practice approaches to community engagement with families. Promoting individual and joint responsibilities for the safety of the family, this toolbox aims to bring families and households together to manage shared risks and agree to safe behaviours critical for their safety and the safety of their community.
