BACKGROUND

To reduce malaria burden in Côte d'Ivoire, the Ministry of Health aims for 90% of its population to possess one long-lasting insecticidal net (LLIN) for every two persons by 2025. This study evaluated LLIN coverage two years after a mass distribution in central Côte d'Ivoire.

METHODS

A census was conducted in 43 villages. Data were collected on household geo-position, composition, number of sleeping units and LLINs owned. LLIN coverage was assessed using: 1/ownership; proportion of household with at least one LLIN; 2/household access; households with sufficient nets for every two persons and for every sleeping unit; and 3/population access; proportion of population with access to LLIN within households and sleeping units.

RESULTS

10,630 households (89.6% response rate) and 46,619 inhabitants were recruited. Household LLIN ownership was 63.8% (95% CI: 58.7-68.8). Household LLIN access was 37.6% (95% CI: 33.2-42.0) based on 1 LLIN per 2 persons and 37.1% (95% CI: 33.0-41.2) based on 1 net per sleeping unit. Population LLIN access based on 1 LLIN per 2 persons and 1 net per sleeping space was 53.3% (95% CI: 48.6-58.1) and 49.4% (95% CI: 45.1-53.6), respectively. Approximately 17% of households with access for every 2 persons did not have access by every sleeping unit and 9.7% of households with access by sleeping unit did not have access for every 2 persons. Households with adequate access by sleeping unit but not for every 2 persons tend to be larger with fewer sleeping units, and have children under 5 years old and female members. The largest households (>7 members) and households with at least one under-five member had the lowest access (20.8 and 27.3%, respectively).

CONCLUSION

LLIN access was low in this area of intense indoor malaria transmission, 2 years after the last mass distribution campaign. Strategies are needed to improve LLINs coverage.

背景

为减轻科特迪瓦的疟疾负担，该国卫生部目标是到2025年，其90%的人口每两人拥有一顶长效驱虫蚊帐（LLIN）。本研究评估了科特迪瓦中部大规模分发长效驱虫蚊帐两年后的覆盖率情况。

方法

在43个村庄开展了普查。收集了家庭地理位置、组成、睡眠单元数量及拥有的长效驱虫蚊帐数量等数据。使用以下指标评估长效驱虫蚊帐覆盖率：1/所有权；拥有至少一顶长效驱虫蚊帐的家庭比例；2/家庭可及性；每两人及每个睡眠单元都有足够蚊帐的家庭；3/人群可及性；家庭和睡眠单元中能使用长效驱虫蚊帐的人群比例。

结果

招募了10630户家庭（应答率89.6%）和46619名居民。家庭长效驱虫蚊帐所有权为63.8%（95%置信区间：58.7 - 68.8）。基于每两人一顶长效驱虫蚊帐，家庭长效驱虫蚊帐可及性为37.6%（95%置信区间：33.2 - 42.0）；基于每个睡眠单元一顶蚊帐，家庭长效驱虫蚊帐可及性为37.1%（95%置信区间：33.0 - 41.2）。基于每两人一顶长效驱虫蚊帐和每个睡眠空间一顶蚊帐，人群长效驱虫蚊帐可及性分别为53.3%（95%置信区间：48.6 - 58.1）和49.4%（95%置信区间：45.1 - 53.6）。每两人有可及性的家庭中，约17%的家庭每个睡眠单元没有可及性；每个睡眠单元有可及性的家庭中，9.7%的家庭每两人没有可及性。每个睡眠单元有足够可及性但每两人没有可及性的家庭往往规模更大，睡眠单元更少，且有5岁以下儿童和女性成员。规模最大的家庭（>7名成员）和至少有一名5岁以下成员的家庭可及性最低（分别为20.8%和27.3%）。
