We studied food and water-borne diseases (FWDs), sexually transmitted diseases (STDs), vector-borne diseases (VBDs) and diseases vaccinated against in the Swedish childhood vaccination programme among Swedish international travellers, in order to identify countries associated with a high number of infections. We used the national database for notifiable infections to estimate the number of FWDs (campylobacteriosis, salmonellosis, giardiasis, shigellosis, EHEC, Entamoeba histolytica, yersinosis, hepatitis A, paratyphoid fever, typhoid fever, hepatitis E, listeriosis, cholera), STIs (chlamydia, gonorrhoea and acute hepatitis B), VBDs (dengue fever, malaria, West Nile fever, Japanese encephalitis and yellow fever) and diseases vaccinated against in the Swedish childhood vaccination programme (pertussis, measles, mumps, rubella, diphtheria) acquired abroad 2009-2013. We obtained number and duration of trips to each country from a database that monthly collects travel data from a randomly selected proportion of the Swedish population. We calculated number of infections per country 2009-2013 and incidence/million travel days for the five countries with the highest number of infections. Thailand had the highest number of FWDs (7,697, incidence 191/million travel days), STIs (1,388, incidence 34/million travel days) and VBDs (358, incidence 9/million travel days). France had the highest number of cases of diseases vaccinated against in the Swedish childhood vaccination programme (8, 0.4/million travel days). Swedish travellers contracted most infections in Thailand. Special focus should be placed on giving advice to travellers to this destination.
我们对瑞典国际旅行者中的食源性和水源性疾病（FWDs）、性传播疾病（STDs）、媒介传播疾病（VBDs）以及瑞典儿童疫苗接种计划中包含的可通过接种预防的疾病进行了研究，以确定与大量感染相关的国家。我们使用国家法定传染病数据库来估算2009 - 2013年期间在国外感染的食源性和水源性疾病（弯曲杆菌病、沙门氏菌病、贾第虫病、志贺氏菌病、肠出血性大肠杆菌、溶组织内阿米巴、耶尔森氏菌病、甲型肝炎、副伤寒热、伤寒热、戊型肝炎、李斯特菌病、霍乱）、性传播感染（衣原体感染、淋病和急性乙型肝炎）、媒介传播疾病（登革热、疟疾、西尼罗河热、日本脑炎和黄热病）以及瑞典儿童疫苗接种计划中包含的可通过接种预防的疾病（百日咳、麻疹、腮腺炎、风疹、白喉）的数量。我们从一个每月收集瑞典随机抽取人群旅行数据的数据库中获取前往每个国家旅行的次数和时长。我们计算了2009 - 2013年每个国家的感染数量以及感染数量最多的五个国家每百万旅行日的发病率。泰国的食源性和水源性疾病感染数量最多（7697例，发病率为每百万旅行日191例）、性传播感染数量最多（1388例，发病率为每百万旅行日34例）以及媒介传播疾病感染数量最多（358例，发病率为每百万旅行日9例）。法国的瑞典儿童疫苗接种计划中包含的可通过接种预防的疾病病例数最多（8例，每百万旅行日0.4例）。瑞典旅行者在泰国感染的疾病最多。应特别着重向前往该目的地的旅行者提供建议。
