Animal health surveillance programmes should be reliable and informative to ensure their effective implementation. As such, the regular assessment of those aiming to demonstrate the absence of disease, as well as the ability to detect outbreaks on time, is of vital importance. Several criteria make it possible to assess the performance of surveillance systems, including timeliness, which represents the speed between steps in a surveillance system. Therefore, the objective of this study was to evaluate the variability in the timeliness, within and between states, of the surveillance programme of the Brazilian Veterinary Services (BVS) for foot‐and‐mouth disease (FMD), for the notification of vesicular disease. A total of 14 years (2004–2017) of data relating to vesicular syndromes from the Brazilian Continental Information and Surveillance System (SivCont) were included. A categorical variable was created with four classes to group the notified vesicular processes in the SivCont, according to two criteria, the similarity of the symptoms of the diseases reported with FMD and aetiology (viral, bacterial, fungal and non‐infectious). The three timeliness values (TL‐1, TL‐2 and TL‐3) related to different portions of the FMD surveillance system were analysed as a response in a generalized linear model in which the states of Brazil were the explanatory variables. The analyses were performed separately for each notification class (FMD, vesicular stomatitis, similar symptoms and similar non‐infectious symptoms) and included comparisons within and between states. The study results provide an understanding and evaluation of the timeliness of the Brazilian FMD surveillance system, thereby providing a base of knowledge from which involved agents and decision‐makers can evaluate BVS and reinforce surveillance measures in the states with poorer timeliness than permitted.

巴西口蹄疫监测计划中水泡疾病通报系统的及时性。

动物健康监测计划应可靠且信息丰富，以确保有效实施。因此，对旨在证明没有疾病以及及时发现疾病爆发能力的人进行定期评估至关重要。几个标准使评估监视系统的性能成为可能，包括及时性，它代表了监视系统各步骤之间的速度。因此，本研究的目的是评估巴西兽医部门（BVS）口蹄疫（FMD）监测，水疱病通报的州内和州之间及时性的差异。 。来自巴西大陆信息与监视系统（SivCont）的总共14年（2004-2017）的数据与囊泡综合症有关。根据两个标准创建了一个分类变量，分为四个类别，以将SivCont中通知的囊泡过程分组，这两个标准是报告的口蹄疫与FMD和病因（病毒，细菌，真菌和非感染性）的相似性。在通用线性模型中，作为口径的回应，分析了与口蹄疫监视系统不同部分相关的三个及时性值（TL-1，TL-2和TL-3），其中巴西的州为解释变量。针对每个通知类别（FMD，水疱性口腔炎，相似症状和相似非感染性症状）分别进行了分析，并包括了州内和州之间的比较。
