Download or read book Determining discriminating concentrations of insecticides for monitoring resistance in sand flies written by World Health Organization and published by World Health Organization. This book was released on 2023-01-10 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The document presents outcome of a WHO multi-centre study (2020–2022) performed by eight laboratories in different WHO regions and the WHO expert consultations that made recommendations to WHO on insecticide discriminating concentrations (DCs) for monitoring resistance in sand fly vectors of leishmaniases. It describes use of the WHO bottle bioassay as a new method for testing susceptibility of sand flies to insecticides that are not suitable for impregnation on filter papers and makes recommendations to WHO on monitoring of insecticide resistance in field populations of sand flies. It also proposes further research to test the new DCs for sand flies in other settings and conditions and to collect evidence from the national disease control programmes and share them with WHO for further assessment and revision of the DCs if required. The current edition of the WHO manual for monitoring insecticide resistance in mosquito vectors and selecting appropriate interventions will be revised using the recommendations made to WHO including for the new DCs for sand flies. The report will be useful to the national vector-borne disease control programmes and the research community for resistance monitoring, and to academia, the pesticide regulatory agencies and the pesticide industry for further innovation in this area and to address the research questions. Please send your suggestions and comments to [email protected] indicating the title of the report and the relevant section and page.

Download or read book Leishmaniases as Re emerging Diseases written by Farhat Afrin and published by BoD – Books on Demand. This book was released on 2018-10-10 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leishmania parasites plague the mammalian host causing high morbidity and mortality. The parasites persist in the hostile milieu, crippling its defensive arsenal. In the face of mounting resistance to an antiquated drug arsenal, new approaches are urgently desired to keep the infection at bay. Furthermore, to strengthen the leishmaniasis elimination drive, particular emphasis has to be laid on identification of new targets and vaccination strategies. This book gives a brief glimpse of the epidemiology of leishmaniasis, immune evasion, vaccination, and therapeutic modalities that may work by untangling the immunological cross-wires of pathogenic cross-talk. The Conventional treatment and its drawbacks, the prospects of phytotherapy and nanomedicines, are also discussed. The identification of drug targets with the aim of designing inhibitors is also exemplified.
Download or read book Toolkit for Integrated Vector Management in Sub Saharan Africa A written by World Health Organization and published by World Health Organization. This book was released on 2016-07-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. It is an extension of earlier guidance and teaching material published by the World Health Organization (WHO): Handbook for integrated vector management Monitoring and evaluation indicators for integrated vector management Guidance on policy-making for integrated vector management and Core structure for training curricula on integrated vector management. 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. Malaria as one of the most important vector-borne diseases in sub-Saharan Africa is the main focus of this document. Programmes targeting other vector-borne diseases can learn from the experiences gained from malaria vector control and presented here.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years many of the conventional methods of insect control by broad spectrum synthetic chemicals have come under scrutiny because of their unde sirable effects on human health and the environment. In addition, some classes of pesticide chemistry, which generated resistance problems and severely affected the environment, are no longer used. It is against this background that the authors of this book present up-to-date findings-relating to biochemical sites that can serve as targets for developing insecticides with selective prop erties, and as the basis for the elucidation of resistance mechanisms and countermeasures. The book consists of eight chapters relating to biochemical targets for insec ticide action and seven chapters relating to biochemical modes of resistance and countermeasures. The authors of the chapters are world leaders in pesti cide chemistry, biochemical modes of action and mechanisms of resistance. Biochemical sites such as chitin formation, juvenile hormone and ecdysone receptors, acetylcholine and GABA receptors, ion channels, and neuropeptides are potential targets for insecticide action. The progress made in recent years in molecular biology (presented in depth in this volume) has led to the iden tification of genes that confer mechanisms of resistance, such as increased detoxification, decreased penetration and insensitive target sites. A combina tion of factors can lead to potentiation of the resistance level. Classifications of these mechanisms are termed gene amplification, changes in structural genes, and modification of gene expression.
Download or read book Communicable Disease Control in Emergencies written by World Health Organization and published by World Health Organization. This book was released on 2005 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This field manual is intended to help health professionals and public health coordinators working in emergency situations prevent, detect and control the major communicable diseases encountered by affected populations. The manual is the result of collaboration among a number of WHO departments and several external partner agencies in reviewing existing guidelines on communicable disease control and adapting them to emergency situations. The manual deals with the fundamental principles of communicable disease control in emergencies, which are: Rapid assessment to identify the communicable disease threats faced by the emergency-affected population, including those with epidemic potential, and define the health status of the population by conducting a rapid assessment; Prevention to prevent communicable disease by maintaining a healthy physical environment and good general living conditions; Surveillance to set up or strengthen disease surveillance system with an early warning mechanism to ensure the early reporting of cases to monitor disease trends, and to facilitate prompt detection and response to outbreaks; outbreak control to ensure outbreaks are rapidly detected and controlled through adequate preparedness (i.e. stockpiles, standard treatment protocols and staff training) and rapid response (i.e.confirmation, investigation and implementation of control measures); and disease management to diagnose and treat cases promptly with trained staff using effective treatment and standard protocols at all health facilities.

Download or read book Bacterial Control of Mosquitoes Black Flies written by Huguette de Barjac and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mosquitoes and black flies are a constant threat to health and comfort, yet the modern chemical pesticides used to control them have cre ated serious ecological problems. Populations of resistant mosquitoes and black flies have evolved, beneficial insects and natural predators have been destroyed, and environmental pollution has increased worldwide. Therefore, scientists have energetically sought new, environmentally safe technologies to combat mosquitoes and black flies and the diseases they carry. Among the most effective alternative means of controlling these pests are the highly spe cific microbial agents derived from Bacillus tburingiensis or Bacillus spbaericus. The microbial control of mosquitoes and black flies is a very important, rapidly developing area of science. Entomologists and microbiologists have already achieved spectacular successes using B. tburingiensis and B. spbaericus against these pests. Recent discoveries of new bacterial isolates specific to new hosts and recent genetic improvements in these isolates have created the potential for wide-scale use of these biological control agents. Efficient microbial control of mosquitoes and black flies can now be achieved, but a proper knowledge of factors relating to the safe and effective use of these biological control agents is necessary. The efficacy of B. tburingiensis and B. spbaericus is influenced by the inherent differential tol erance of the target mosquitoes or black flies, by the formulation technology and application of these agents, and by environmental factors, especially sun light and temperature.
