Control of dog-mediated rabies relies on raising awareness, access to post-exposure prophylaxis (PEP) and mass dog vaccination. To assess rabies awareness in Moramanga district, Madagascar, where rabies is endemic, two complementary quantitative and qualitative approaches were carried out in 2018. In the quantitative approach, a standardized questionnaire was administered to 334 randomized participants living in 170 households located less than 5 km from the anti-rabies treatment center (ARTC) located in Moramanga city (thereafter called the central area), and in 164 households located more than 15 km away from the ARTC in two rural communes (thereafter called the remote area). Logistic regression models were fitted to identify factors influencing knowledge and practice scores. The qualitative approach consisted in semi-structured interviews conducted with 28 bite victims who had consulted the ARTC, three owners of biting dogs, three ARTC staff and two local authorities. Overall, 15.6% (52/334) of households owned at least one dog. The dog-to-human ratio was 1:17.6. The central area had a significantly higher dog bite incidence (0.53 per 100 person-years, 95% CI: 0.31-0.85) compared to the remote area (0.22 per 100 person-years, 95% CI: 0.09-0.43) (p = 0.03). The care pathway following a bite depended on wound severity, how the dog was perceived and its owner's willingness to cover costs. Rabies vaccination coverage in dogs in the remote area was extremely low (2.4%). Respondents knew that vaccination prevented animal rabies but owners considered that their own dogs were harmless and cited access and cost of vaccine as main barriers. Most respondents were not aware of the existence of the ARTC (85.3%), did not know the importance of timely access to PEP (92.2%) or that biting dogs should be isolated (89.5%) and monitored. Good knowledge scores were significantly associated with having a higher socio-economic status (OR = 2.08, CI = 1.33-3.26) and living in central area (OR = 1.91, CI = 1.22-3.00). Good practice scores were significantly associated with living in central area (OR = 4.78, CI = 2.98-7.77) and being aware of the ARTC's existence (OR = 2.29, CI = 1.14-4.80). In Madagascar, knowledge on rabies was disparate with important gaps on PEP and animal management. Awareness campaigns should inform communities (i) on the importance of seeking PEP as soon as possible after an exposure, whatever the severity of the wound and the type of biting dog who caused it, and (ii) on the existence and location of ARTCs where free-of-charge PEP is available. They should also encourage owners to isolate and monitor the health of biting dogs. Above all, awareness and dog vaccination campaigns should be designed so as to reach the more vulnerable remote rural populations as knowledge, good practices and vaccination coverage were lower in these areas. They should also target households with a lower socio-economic status. If awareness campaigns are likely to succeed in improving access to ARTCs in Madagascar, their impact on prompting dog owners to vaccinate their own dogs seems more uncertain given the financial and access barriers. Therefore, to reach the 70% dog vaccination coverage goal targeted in rabies elimination programs, awareness campaigns must be combined with free-of-charge mass dog vaccination.
控制犬介导的狂犬病依赖于提高认识、接触后预防(PEP)和大规模犬疫苗接种。为了评估马达加斯加莫兰加地区的狂犬病意识,该地区狂犬病流行,我们在 2018 年进行了两种补充的定量和定性方法。在定量方法中,对居住在距离位于莫兰加市的抗狂犬病治疗中心(ARTC)不到 5 公里的 170 户家庭中随机选择的 334 名参与者和居住在距离 ART 中心超过 15 公里的两个农村公社中 164 户家庭(此后称为偏远地区)的 334 名参与者进行了标准化问卷调查。使用逻辑回归模型确定影响知识和实践评分的因素。定性方法包括对咨询 ARTC 的 28 名咬伤受害者、3 名咬狗的主人、3 名 ARTC 工作人员和 2 名地方当局进行半结构化访谈。总体而言,334 户家庭中有 15.6%(52/334)拥有至少一只狗。犬与人的比例为 1:17.6。与偏远地区(0.22 人/年,95%CI:0.09-0.43)相比,中心区的犬咬伤发生率(0.53 人/年,95%CI:0.31-0.85)显著更高(p = 0.03)。咬伤后的护理途径取决于伤口的严重程度、狗的认知方式以及主人支付费用的意愿。偏远地区犬疫苗接种覆盖率极低(2.4%)。受访者知道疫苗接种可以预防动物狂犬病,但狗主人认为自己的狗没有危险,并提到了疫苗的可及性和成本是主要障碍。大多数受访者不知道 ARTC 的存在(85.3%),不知道及时获得 PEP 的重要性(92.2%),也不知道应该隔离(89.5%)和监测咬人的狗。良好的知识评分与较高的社会经济地位(OR = 2.08,CI = 1.33-3.26)和居住在中心区(OR = 1.91,CI = 1.22-3.00)显著相关。良好的实践评分与居住在中心区(OR = 4.78,CI = 2.98-7.77)和知道 ARTC 的存在(OR = 2.29,CI = 1.14-4.80)显著相关。在马达加斯加,狂犬病知识存在差异,PEP 和动物管理方面存在重要差距。宣传活动应告知社区:(i)无论伤口严重程度和导致伤口的咬狗类型如何,在接触后尽快寻求 PEP 的重要性;(ii)ARTC 的存在和位置,在那里可以获得免费的 PEP。它们还应鼓励主人隔离和监测咬人的狗的健康状况。最重要的是,应设计提高认识和犬疫苗接种运动,以覆盖更脆弱的偏远农村地区,因为这些地区的知识、良好做法和疫苗接种覆盖率较低。它们还应针对社会经济地位较低的家庭。如果提高认识运动有可能成功改善对 ARTC 的获取,考虑到经济和获取障碍,它们对促使狗主人为自己的狗接种疫苗的影响似乎更不确定。因此,为了实现狂犬病消除计划中 70%的犬疫苗接种覆盖率目标,提高认识运动必须与免费的大规模犬疫苗接种相结合。
