BACKGROUND
For decades La Réunion has experienced a number of epidemics that have resulted in efforts to control the density of Aedes species on this Island. This study was conducted to assess household-level expenditure on protective measures against mosquito nuisance on the Island of La Réunion in 2012.
METHODOLOGY/PRINCIPAL FINDINGS: Data was collected during a cross-sectional survey of 1024 households and used to determine the relationship between the use of chemically-based protective measures and subjective and objective indicators of the density of Aedes albopictus. The average household expenditure in July 2012 was USD 9.86 and the total household-level expenditure over a one-year period was extrapolated to USD 28.05million (range: USD 25.58 million to USD 30.76 million). Much of this money was spent on measures thought to be relatively ineffective against Aedes mosquitoes. Expenditure on protective measures was not influenced by the level of knowledge on mosquitoes or by the visual nuisance they generated at home, but rather by the perception of risk related to a future epidemic of chikungunya and socioeconomic factors. Most importantly, household spending on protective measures was found to be influenced by a measure of zone-level mosquito density (the Breteau index), but not by objective indicators of the presence of mosquitoes within or around the house.
CONCLUSIONS/SIGNIFICANCE: Household-level expenditure on chemically-based protective measures is high when compared to the investment made by public entities to achieve vector control, and it is differentially influenced by subjective and objective measures of mosquito density. The current situation could be improved, firstly by ensuring that the public is well-informed about mosquitoes and the effectiveness of various protective measures, and secondly by implementing interventions that could either complement current vector-control strategies and improve their effectiveness on a country-level, or that would steer the population toward the appropriate behaviours.
背景
几十年来，留尼汪岛经历了多次疫情，促使人们努力控制该岛伊蚊的密度。本研究旨在评估2012年留尼汪岛家庭层面用于防蚊措施的支出。
方法/主要发现：在对1024户家庭进行的横断面调查中收集数据，以确定基于化学的防护措施的使用与白纹伊蚊密度的主观和客观指标之间的关系。2012年7月家庭平均支出为9.86美元，一年内全岛家庭层面的总支出推算为2805万美元（范围：2558万美元至3076万美元）。这笔钱大部分花在了被认为对伊蚊相对无效的措施上。防护措施的支出不受对蚊子的了解程度或家中蚊子造成的视觉干扰的影响，而是受与未来基孔肯雅热疫情相关的风险认知和社会经济因素的影响。最重要的是，发现家庭在防护措施上的支出受区域层面蚊子密度指标（布雷图指数）的影响，但不受房屋内或周围蚊子存在的客观指标的影响。
结论/意义：与公共实体为实现病媒控制所做的投资相比，家庭层面基于化学的防护措施支出较高，且受蚊子密度的主观和客观指标的不同影响。首先，通过确保公众充分了解蚊子以及各种防护措施的有效性，其次，通过实施干预措施，要么补充当前的病媒控制策略并提高其在国家层面的有效性，要么引导民众采取适当行为，当前状况有望得到改善。
