In recent years, arboviruses have become increasingly important in Europe due to autochthonous outbreaks of emerging and re-emerging diseases such as chikungunya fever, dengue and Zika. These viruses represent a threat in temperate areas such as the Valencian Community (CV), where the presence of their vector, the Asian tiger mosquito, is widely distributed. The objective of this work was to report on the actions carried out within the CV Programme, in the management of declared cases of imported arboviruses from 2016 to 2021.
To this end, coordinated work procedures had been implemented between the Generalitat Valenciana and the University of Valencia in order to reduce the risk of autochthonous transmission through detection, surveillance and monitoring of the vector, as well as entomological surveys in the vicinity of the residence of infected citizens. The sample size consisted of forty-five imported cases, which had been analysed with the statistical software R version 3.3.
The presence of established tiger mosquito populations had been corroborated in a total of 273 municipalities during the study period, increasing the number of affected localities by the end of 2021 to 464 out of the total of 542 in the VC. The response time from the onset of symptoms to diagnosis, the time elapsed from diagnosis to reporting to the corresponding Environmental Health Unit and the completion of the entomological survey had been evaluated.
Vector surveillance is essential. The time between the onset of the patient's symptoms and the diagnosis by health professionals must be reduced. The most numerous imported cases are those of dengue from Asia and Central America with 87.5% of hospitalizations.
近年来，由于基孔肯雅热、登革热和寨卡等新出现和再次出现的疾病在欧洲本土爆发，虫媒病毒在欧洲变得越来越重要。这些病毒在巴伦西亚自治区（CV）等温带地区构成威胁，其传播媒介亚洲虎蚊在该地区广泛分布。这项工作的目的是报告CV计划在2016年至2021年期间对申报的输入性虫媒病毒病例的管理行动。
为此，巴伦西亚自治区政府和瓦伦西亚大学实施了协调的工作程序，以通过对媒介的检测、监测和监控以及在受感染公民住所附近进行昆虫学调查来降低本土传播的风险。样本量包括45例输入性病例，已使用统计软件R版本3.3进行分析。
在研究期间，总共273个城市证实存在既定的虎蚊种群，到2021年底，受影响地区的数量增加到VC总共542个城市中的464个。评估了从症状出现到诊断的响应时间、从诊断到向相应环境卫生部门报告的时间以及昆虫学调查的完成时间。
媒介监测至关重要。必须缩短患者症状出现到卫生专业人员诊断之间的时间。输入性病例最多的是来自亚洲和中美洲的登革热病例，住院率为87.5%。
