背景疾病控制和预防中心通过两个监测系统监测弧菌病：全国霍乱和其他弧菌疾病监测系统（COVIS）和10个州食源性疾病主动监测网络（FoodNet）。COVIS进行被动监测，FoodNet对实验室确认的弧菌感染进行主动监测。我们总结了从1996年到2010年向COVIS和FoodNet报告的弧菌感染（不包括致炎性霍乱弧菌O 1和O 139）。对于每个系统，我们使用美国人口普查局对监测区域的人口估计来计算发病率。从1996年到2010年，向COVIS报告了7700例弧菌病，向FoodNet报告了1519例。从1996年到2010年，两个系统中每10万人报告的弧菌病年发病率都有所增加，COVIS从0.09增加到0.28，FoodNet从0.15增加到0.42。3种常见的弧菌属为副溶血弧菌、创伤弧菌和溶藻弧菌;两种监测系统均显示每种弧菌的发病率增加。在这两个系统中，大多数住院和死亡都是由创伤弧菌感染引起的，大多数患者是白色男性。病例数在夏季达到高峰。COVIS和FoodNet的监测数据表明，从1996年到2010年，弧菌病的发病率总体上增加了，并且对于3种最常见的报告物种中的每一种。两个系统的流行病学模式相似。目前的预防工作未能防止弧菌病发病率的上升;需要采取更有效的措施来降低发病率。
Background. The Centers for Disease Control and Prevention monitors vibriosis through 2 surveillance systems: the nationwide Cholera and Other Vibrio Illness Surveillance (COVIS) system and the 10-state Foodborne Diseases Active Surveillance Network (FoodNet). COVIS conducts passive surveillance and FoodNet conducts active surveillance for laboratory-confirmed Vibrio infections.Methods. We summarized Vibrio infections (excluding toxigenic V. cholerae O1 and O139) reported to COVIS and FoodNet from 1996 through 2010. For each system, we calculated incidence rates using US Census Bureau population estimates for the surveillance area.Results. From 1996 to 2010, 7700 cases of vibriosis were reported to COVIS and 1519 to FoodNet. Annual incidence of reported vibriosis per 100 000 population increased from 1996 to 2010 in both systems, from 0.09 to 0.28 in COVIS and from 0.15 to 0.42 in FoodNet. The 3 commonly reported Vibrio species were V. parahaemolyticus, V. vulnificus, and V. alginolyticus; both surveillance systems showed that the incidence of each increased. In both systems, most hospitalizations and deaths were caused by V. vulnificus infection, and most patients were white men. The number of cases peaked in the summer months.Conclusions. Surveillance data from both COVIS and FoodNet indicate that the incidence of vibriosis increased from 1996 to 2010 overall and for each of the 3 most commonly reported species. Epidemiologic patterns were similar in both systems. Current prevention efforts have failed to prevent increasing rates of vibriosis; more effective efforts will be needed to decrease rates.
