In Cameroon, since the first epidemiological week held in 2015, snakebites have been registered among Potential Epidemic Diseases (PED). In the Centre Region, the most densely populated of the country, weekly reports of snakebites are generated at health districts level for monthly data updates.
To contribute to the better management of snakebite cases, an observational study was conducted to assess the snakebite reporting rate in the Centre Region of Cameroon. The results of this retro-prospective survey were confronted to those of the weekly epidemiological surveillance system, recorded in the PED regional data base.
The incidence of bites was relatively high (36.6 bites per 100,000 inhabitants), as well as the general attack rate (about 49 envenomations per 100 victims). The lethality recorded was 2.5% and the mortality was about 1 death per 100,000 inhabitants a year. The sex ratio was largely female biased (61.6%). The bites occurred mostly during the rainy season (73.0%). Bitten victims were mainly farmers (47.4%), and agriculture was the main risk factor. The comparative analysis of the data suggested a high non-reporting rate of snakebite cases (67.8%).
Snakebite is an endemic condition in the Centre Region of Cameroon. Because of the high rate of non-reporting of cases, the collection of information from the registers of the health facilities only appears not enough to assess the real importance of envenomation in this Region.
自 2015 年开展第一周的流行病学调查以来，喀麦隆的蛇伤已被纳入潜在传染病（PED）监测。在该国人口最密集的中心大区，各卫生区每周都会报告蛇伤病例，以便每月更新数据。
为了更好地管理蛇伤病例，我们开展了一项观察性研究，评估喀麦隆中心大区的蛇伤报告率。该回顾性前瞻性调查的结果与 PED 大区数据库中记录的每周流行病学监测系统的结果进行了对比。
咬伤发病率相对较高（每 10 万人中有 36.6 例咬伤），总攻击率（每 100 名受害者中有约 49 例中毒）也较高。记录的死亡率为 2.5%，每年每 10 万居民中有 1 例死亡。性别比严重偏向女性（61.6%）。咬伤大多发生在雨季（73.0%）。咬伤受害者主要是农民（47.4%），农业是主要的风险因素。数据分析表明，蛇伤病例的报告率很高（67.8%）。
蛇伤是喀麦隆中心大区的地方病。由于病例报告率很高，仅从卫生机构的登记册中收集信息似乎不足以评估该地区中毒的真实重要性。
