As the number of transboundary pest and animal and foodborne disease outbreaks rises, so does the number of people who are chronically hungry due to these and other factors. The correlation can be explained by the link between our health and that of the planet. We rely on land and sea for the produc...tion of safe and quality foods for our daily nourishment. Pests and disease epidemics negatively impact the quality, quantity and safety of our food sources, and cripple economic growth and efficiencies in production. Furthermore, the epidemic and endemic levels of the pathogens and disease vectors can be difficult to control. This is why FAO stresses and promotes the special efforts required for cost-effective preventive measures rather than the more expensive control, disinfestation, treatment and disposal measures. When preventive measures are late or difficult, preparedness and contingency plans must be in place to enable rapid response. Early warning systems, based on close monitoring, surveillance, and timely reporting are fundamental to warn and empower communities to safeguard their livelihoods and assets by enhancing disease and pest prevention measures and for government services to take immediate measures to protect communities and national economies.

Mass population movements have accounted for the emergence of Chagas disease (CD) outside endemic regions,
including the European Union/European Economic Area (EU/EEA). The parasite responsible for causing CD,
Trypanosoma cruzi (T. cruzi), can be transmitted through substances of human origin (SoH...O), such as blood
transfusions and organ transplantations [1], posing a risk to the recipients. This, together with congenital
transmission, is of increasing concern in non-endemic countries

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.

The document explains why vector control is important in national programmes and describes the preparation of a tailor-made vector control plan for national programmes. It outlines entomological procedures for regular and specific vector control and how data should be analysed for better overall und...erstanding of filarial transmission and vectors. The document will also be useful for teaching personnel in lymphatic filariasis programmes about the use and value
of entomological procedures in overall epidemiological appraisal in the context of

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.

This action plan is intended for senior-level decision-makers in ministries of health, malaria
programme managers, entomologists, and epidemiologists working on malaria and other vectorborne diseases programmes. It is also intended for decision-makers and technical and advocacy
staff at other orga...nizations and stakeholders involved in public health, malaria control and
elimination, and urban and rural development.

Cities are uniquely positioned to understand local needs and respond rapidly to changing conditions to safeguard health. These changes require strong city leadership to implement multisectoral, health-relevant policies and public services that engage communities. The response to malaria must be an i...ntegral part of such policies and processes.
This framework supports the control and elimination of malaria in urban environments. It provides guidance for city leaders, health programmes and urban planners as they respond to the challenges of rapid urbanization in a targeted way. For each urban context, the strategic use of data can inform effective, tailored responses and help build resilience against the threat of malaria and other vector-borne diseases.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

This template dossier complements and should be used after fulfilling the criteria and preconditions specified in the Process of validation of elimination of kala-azar as a public health problem in South-East Asia. The national kala-azar programme should be in the consolidation phase of elimination;... that is, the annual incidence of kala-azar in the implementation unit is maintained below 1 case (new plus relapse) per 10 000 population for a minimum of 3 consecutive years.
The template is designed to help national kala-azar elimination programmes prepare a dossier documenting the essential evidence supporting the request to the World Health Organization (WHO) to validate the status of kala-azar elimination as a public health problem in their country. The information presented in this document will help independent assessors understand the national programme’s specific context, achievements and relevant epidemiological data.
The dossier should be organized according to the following sections:
- Description of the country context and health system capabilities
- Historical data and delineation of endemic areas
- Surveillance and elimination activities
- Epidemiological data
- Vector control strategy and activities
- Post-validation surveillance plan
Once the dossier is prepared, it should be examined and duly endorsed by the National Task Force on kala-azar elimination and/or neglected tropical diseases, or a similar body, before submission to WHO.

Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission
