Rabies persists as a longstanding issue in Zambia, despite being preventable. The current control measures, including dog vaccination, population control, and movement restriction, guided by 'The Control of Dogs Act Chapter 247 of the Laws of Zambia', have not yielded the desired impact in many areas of the country including Manyinga and Mwansabombwe districts. These two districts continue to report low dog vaccination rates, unrestricted dog movements, and escalating cases of animal and human rabies, along with dog bites. Aligned with global aspirations to achieve zero human rabies cases by 2030, this study scrutinizes the determinants and obstacles hampering the execution of rabies control initiatives in Manyinga and Mwansabombwe. Spanning approximately 11 months, this cross-sectional study gathered pre- and post-vaccination data from 301 households in Manyinga and 100 households in Mwansabombwe. Questionnaires probed knowledge, attitudes, and practices related to rabies prevention and control. A transect survey, key informant interviews, and assessment of rabies vaccination and dog bite records complemented the data collection. Findings revealed that 88.0% of respondents from both districts possessed knowledge about rabies, confirming affected species and transmission. Moreover, 76.8% in Manyinga and 88.6% in Mwansabombwe were acquainted with rabies prevention and control methods. Concerning dog owners, 89.0% were aware of rabies, 66.0% understood its prevention and control, and the majority identified bites as the primary mode of transmission. Despite the high level of knowledge recorded during the survey, the implementation of preventive measures was low, which was attributed to low levels of law enforcement by the local government authority, inadequate staffing in the veterinary department, unwillingness to pay for dog vaccinations, and unavailability of rabies vaccine at the veterinary office in both districts. Vaccination coverage stood at 64.0% in Manyinga and 21.0% in Mwansabombwe. Notably, education and occupation exhibited a positive significant association with rabies knowledge. In terms of dog bite cases, Manyinga recorded 538 dog bite cases from 2017 to June 2022, while Mwansabombwe recorded 81 dog bite and 23 jackal bite cases from 2021 to June 2022. The study underscores critical knowledge gaps in rural areas and emphasizes the imperative for enhanced public education and awareness programs, improved rabies surveillance, free mass vaccination campaigns, and community engagement to augment vaccination coverage and knowledge about rabies.
尽管狂犬病是可预防的,但在赞比亚它仍然是一个长期存在的问题。目前的控制措施,包括依据《赞比亚法律第247章:犬类控制法案》进行的犬类疫苗接种、数量控制和行动限制,在该国的许多地区,包括曼因加和姆万萨邦布韦区,并未产生预期效果。这两个区继续报告犬类疫苗接种率低、犬类行动不受限制,以及动物和人类狂犬病病例以及犬咬伤人事件不断增加。为了与到2030年实现人类狂犬病病例零发生的全球目标保持一致,本研究审视了阻碍曼因加和姆万萨邦布韦狂犬病控制举措实施的决定因素和障碍。这项横断面研究历时约11个月,收集了曼因加301户家庭和姆万萨邦布韦100户家庭接种疫苗前后的数据。问卷询问了与狂犬病预防和控制相关的知识、态度和做法。横断面调查、关键信息提供者访谈以及狂犬病疫苗接种和犬咬伤人记录评估对数据收集起到了补充作用。研究结果显示,两个区88.0%的受访者了解狂犬病,确认了受影响的物种和传播途径。此外,曼因加76.8%的受访者和姆万萨邦布韦88.6%的受访者了解狂犬病的预防和控制方法。关于犬主,89.0%的人知晓狂犬病,66.0%的人了解其预防和控制方法,且大多数人认定咬伤是主要传播方式。尽管调查中记录的知识水平较高,但预防措施的实施率较低,这归因于地方政府执法力度不足、兽医部门人员配备不足、不愿支付犬类疫苗接种费用以及两个区的兽医办公室均无狂犬病疫苗。曼因加的疫苗接种覆盖率为64.0%,姆万萨邦布韦为21.0%。值得注意的是,教育程度和职业与狂犬病知识呈显著正相关。在犬咬伤人事件方面,曼因加在2017年至2022年6月期间记录了538起犬咬伤人事件,而姆万萨邦布韦在2021年至2022年6月期间记录了81起犬咬伤人事件和23起胡狼咬伤人事件。该研究强调了农村地区存在的关键知识差距,并强调必须加强公众教育和宣传项目、改善狂犬病监测、开展免费大规模疫苗接种活动以及促进社区参与,以提高疫苗接种覆盖率和狂犬病知识水平。
