“…39 Data collection and interpretation related to complex emergencies is often different from regular malaria programming and is a critical aspect of reaching the unreached in these situations. 40 Ironically, the unreached can sometimes be hidden in a community where government or donor-supported services target only young children or set other "specific coverage" targets. 41 Children aged 5 years and older, older adolescents, and adults can often serve as reservoirs for malaria, not getting sick immediately or only modestly.…”

“…Effective malaria control must be able to be conducted in unstable and difficult conditions if short to mid-term goals of mortality reduction are to be met. However acute or protracted emergency conditions often preclude this to be done optimally and there remains a gap in the literature, particularly regarding the most efficient malaria-control approaches to deploy in a given context [ 3 ]. Such conditions require an emphasis on different or adapted tools with specific characteristics that may not be as relevant in more stable contexts, where access to the population is usually better, and the type of household allows for the use of existing tools developed mainly for stable settings.…”

Background The use and implementation of novel tools for malaria control such as long lasting impregnated bednets (LLINs) and Indoor Residual Spraying (IRS) over the last decade has contributed to a substantial reduction in malaria burden globally. However numerous challenges exist particularly in relation to vector control in emergency settings. This study seeks to explore expert opinion on the utility of existing tools within the emergency context setting and to better understand the attitude towards emerging and innovative tools (including Genetically Modified Mosquitoes) to augment current approaches. Methods 80 experts in the field of malaria and vector control were invited to participate in a two-round Delphi survey. They were selected through a combination of literature (academic and policy publications) review and snowball sampling reflecting a range of relevant backgrounds including vector control experts, malaria programme managers and emergency response specialists. The survey was conducted online through a questionnaire including the possibility for free text entry, and concentrated on the following topics: Utility and sustainability of current vector control tools, both in and outside emergency settings Feasibility, utility and challenges of emerging vector control tools, both in and outside emergency settings Current and unmet research priorities in malaria vector control and in malaria control in general. Results 37 experts completed the first round and 31 completed the second round of the survey. There was a stronger consensus about the increased utility of LLIN compared to IRS in all settings, while insecticide-treated covers and blankets ranked very high only in emergency settings. When considering the combination of tools, the ones deemed most interesting always involved LLINs and IRS regardless of the setting, and the acceptability and the efficacy at reducing transmission are essential characteristics. Regarding perceptions of tools currently under development, consensus was towards improvement of existing tools rather than investing in novel approaches and the majority of respondents expressed distrust for genetic approaches. Conclusion Malaria vector control experts expressed more confidence for tools whose efficacy is backed up by epidemiological evidence, hence a preference for the improvement rather than the combination of existing tools. Moreover, while several novel tools are under development, the majority of innovative approaches did not receive support, particularly in emergency settings. Stakeholders involved in the development of novel tools should involve earlier and raise awareness of the potential effectiveness amongst a wider range of experts within the malaria community to increase acceptability and improve early adoption once the evidence base is established.
