  • The purpose of this presentation is to describe the various interventions that comprise a comprehensive, integrated mosquito and malaria control (IMMC) program.
  • Tr-Ac-Net (Peter Burgess) has collected a lot of material from peer reviewed papers about the costs of various interventions, but the information is, by good cost accounting standards, rather weak and not at all clear
    The reference material is listed in a “reference” file. Many of the authors of the papers have been contacted for clarification and guidance ... and an encouraging number of authors have shown interest in the IMMC Consortium initiative.
  • Aerial treatment is very cost effective when the operations are used optimally. Work done is fast, and results can be significant.
    But operations need to be driven by good data, good analysis and good science.
    Aerial operations can do work in areas that cannot be reached easily on the ground ... marshy areas and informal shantytown areas with limited road access.
    Very low volumes of insecticide are used ... ultra low volume (ULV) droplets are tiny and kill mosquitoes while they are flying. The residue may never actually reach the ground.
    Other techniques such as larvaciding are effective when applied precisely where needed ... this requires good data and equipment such as GPS gear to operate with precision.
  • This is just an introduction.
    More information is available in a variety of formats including pdf files, spreadsheet versions and presentation files.
    Generally speaking this material is available free to members of the Transparency and Accountability Network (Tr-Ac-Net Inc.) a not for profit corporation incorporated in Vermont USA. Contact Tr-Ac-Net ([email_address] or www.tr-ac-net.org) about becoming a member.
    The major theme of Tr-Ac-Net information is the critical value of management information, the decision making process and accounting and accountability.
    Another recurrent theme is the importance of value adding activities in socio-economic progress, and the profile of the value chains so that there is reasonable equity between all the legitimate stakeholders.
  • Integrated Malaria Management

    1. 1. Integrated Malaria Management (IMM) October 2009 Revised July 2014
    2. 2. Integrating Mosquito and Malaria Control Modern science gives us the tools to have rapid and low cost success ... but only if the program is driven by science and facts about the situation, and the performance of program interventions. The goal is to reduce the negative impact of malaria in African communities ... rapidly and at lowest possible cost. The aim of integrating mosquito and malaria control is that very much more cost effective results can be achieved in any community through a multi-intervention approach than any single intervention approach. With IMM data are used to make plans and judge results. Integrated Malaria Management
    3. 3. A critical parameter of success is reduction in the rate of re-infection. No matter how good the malaria therapy, malaria will remain a socio-economic problem of major proportion as long as there is a continuing cycle of re-infection. This is one of the reasons for the build up of resistance to drugs, and a reason that stand-alone malaria control programs do not succeed. Disrupting the Continuing Cycle of Re-infection Integrated Malaria Management
    4. 4. The IMM Components ● Collect data (entomological data, environmental data, spatial data, medical data, cost data) and do thorough, rapid analysis to define and optimize interventions and program activities. ● Do environmental cleanup and get community involved. ● Use interior residual spraying (IRS) to control mosquitoes near human beings. Use best available insecticides, including DDT. ● Use larvicides to control (stop) the maturation of mosquitoes. ● Kill / control flying mosquito population using aerial and ground application of adulticides. ● Medical - malaria case management to improve health situation and reduce malaria parasite in the area. ● Use insecticide impregnated bednets to limit mosquito bites. Integrated Malaria Management
    5. 5. Management Process Collect data Do analysis Make operational decisions Collect more data Do more analysis Revise operational decisions Publish performance to all stakeholders Integrated Malaria Management
    6. 6. Collect data – get it from the habitat. Not comfortable, but very important. Learn WHERE and what is going on with the mosquito: larva ... mosquito population ... prevalence of malaria in the mosquitoes ... etc. Collect Data: Entomology Integrated Malaria Management
    7. 7. Left picture: A satellite image of Monrovia, Liberia, West Africa showing 15,000 acres of marsh within the main urban area (dark brown area) Right picture: Aerial image of part of the urban area ... very congested and difficult to access by vehicle. Collect Data: Geographical Integrated Malaria Management
    8. 8. Keep score ... the goal is to reduce the prevalence of malaria, and to do it at least cost and in the most sustainable manner. Part of this requires knowledge of issues like resistance and the cost and effectiveness of various forms of therapy. Collect Data – Malariology Integrated Malaria Management
    9. 9. Everyone needs to have access to treatment ... it is important for two reasons: (1) the patients need treatment to get better and avoid getting worse; and (2) good public health policy requires that there is a lowering of malaria prevalence as fast as possible to give a sustainable outcome. This child did not get adequate treatment ... this clinic did not have effective medications ... as reported in the New York Times in June 2006 Collect Data – about malaria and treatment Integrated Malaria Management
    10. 10. Data is used to determine what interventions are most likely to give rapid sustainable progress towards the ultimate goal of reducing malaria prevalence. A cost and operations model suggests that best practice using multiple interventions is several times more cost effective than any other approach. Data analysis, cost and value optimization Integrated Malaria Management
    11. 11. Operational Components Environmental Cleanup Interior Residual Spraying (IRS) Larviciding Exterior Spraying (Air ULV, Ground Fogging) Medical Treatment Bednets (ITN) Integrated Malaria Management
    12. 12. Stagnant water facilitates mosquito breeding. Cleanup is something that people in all communities should undertake as a civic responsibility. It takes education, leadership and motivation. This can be organized through community groups like churches and mosques, youth groups, soccer teams, etc. This should be one of many IMM interventions. Environmental Cleanup Integrated Malaria Management
    13. 13. Interior Residual Spraying (IRS) has been very effective in reducing the incidence of malaria ... and especially when DDT is used as the primary insecticide. IRS operates in three ways: (1) as a repellant that keep mosquitoes outside the living space; (2) as an irritant that accelerates exit of mosquitoes; and, (3) toxicity that kills mosquitoes. Interior Residual Spraying (IRS) Integrated Malaria Management
    14. 14. The best time to eliminate the mosquito vector is BEFORE the mosquito can fly. This can be done with knowledge about the environment and larviciding to kill larva before they become flying mosquitoes. Various approaches to larviciding are possible ... manual, with mechanized support and, in some cases, using aerial application. Larviciding Integrated Malaria Management
    15. 15. ● Aerial spraying makes rapid treatment of large and/or inaccessible areas possible. ● Aerial operations are expensive per hour, but LOW COST in terms of work done. ● Ultra Low Volume (ULV) spraying does NO environmental damage. ● Treatment strategy determined by entomological analysis. Aerial Treatment – ULV, Adulticiding, Larviciding Integrated Malaria Management
    16. 16. Ultra Low Volume (ULV) and aerosol ground fogging is common practice in places where malaria has been controlled. It serves to reduce mosquito populations in areas reached by insecticide sprays and limit malaria transmission. A variety of chemicals are used that are highly toxic to mosquitoes but safe for humans, animals and the environment. By varying the chemicals used build up of resistance is minimized. ULV Ground Fogging – mechanized and manual Integrated Malaria Management
    17. 17. The need for malaria treatment is enormous ... over 400 million cases a year in Africa. But most do not get effective treatment. Public funding for programs is small, and most individuals do not have their own resources. Untreated malaria can be fatal. Use effective drugs. Avoid building up drug resistance. Treatment Integrated Malaria Management
    18. 18. Insecticide treated bednets (ITN) help reduce malaria transmission. They reduce contact with malaria infected mosquitoes and reduce malaria among people using bednets. But what about protection outside the house? Insecticide Treated Bednets (ITN) Widespread bednet use requires a lot of effort and bednets are expensive relative to local incomes. ITN is a valuable part of a total solution, but only a part. ITN cannot achieve full success on its own. Integrated Malaria Management
    19. 19. The Panama Canal Zone around 1904. Most of temperate Europe ended malaria largely by improved environment that reduced vector. USA eliminated endemic malaria Japan almost totally reduced malaria Italy and lastly Sardinia reduced malaria India had major reduction in malaria prevalence Considerable reduction in Caribbean locations Considerable reduction in Latin America Australia eliminated endemic malaria South Africa, Swaziland and Mozambique used regional control and IRS (including use of DDT) to reduce malaria epidemic arising after about 10 years of no DDT use. Examples of success Success in the early part of the 20th Century Immediate post WW2 era to around 1960 (heavy use of DDT) Recent experience in Africa Integrated Malaria Management
