Through the analysis of notified viral hepatitis, trends in the occurrence of imported cases in the Czech Republic have been specified, the aim of which was to draw attention to the epidemiologically important aspects of travelling abroad.
In the software environment of Epi Info version 6.04d, nationwide databases of communicable diseases over the period of 1993-2005 were analysed. The period was defined with respect to the availability of necessary data in the Epidat information system for communicable disease reporting in the Czech Republic.
During the years 1993-2005, 12,091 cases of communicable diseases were imported into the Czech Republic of which viral hepatitis accounted for 5.7 % (685). The rates by diagnosis were as follows: viral hepatitis A 61 %, acute viral hepatitis B 15 %, chronic viral hepatitis C 11 %, viral hepatitis E 5 %, acute viral hepatitis C 3 %, chronic viral hepatitis B 3 % and other cases of viral hepatitis 2 %. The rates by the "imported by" variable: Czech tourists 47.2 %, foreigners 32.8 %, Czech business travellers 20.0 %. The diseases were most commonly imported from the following countries: Ukraine 13 %, Slovakia 8 %, Southern Europe 6 %, Egypt 6 % and Russia 5 %.
In the Czech Republic, communicable diseases are reported using the Epidat system. The Epidat database analysis focused on reported cases of imported viral hepatitis represents an important starting point for assessing health risks associated with travelling abroad.
通过对通报的病毒性肝炎进行分析，明确了捷克共和国输入性病例的发病趋势，其目的是引起人们对出国旅行在流行病学方面重要问题的关注。
在Epi Info 6.04d软件环境下，对1993 - 2005年期间全国范围内的传染病数据库进行了分析。该时间段是根据捷克共和国传染病报告的Epidat信息系统中必要数据的可获取情况确定的。
在1993 - 2005年期间，捷克共和国共输入12,091例传染病病例，其中病毒性肝炎占5.7%（685例）。按诊断分类的比例如下：甲型病毒性肝炎61%，急性乙型病毒性肝炎15%，慢性丙型病毒性肝炎11%，戊型病毒性肝炎5%，急性丙型病毒性肝炎3%，慢性乙型病毒性肝炎3%，其他病毒性肝炎病例2%。按“输入者类型”变量分类的比例：捷克游客47.2%，外国人32.8%，捷克商务旅行者20.0%。这些疾病最常从以下国家输入：乌克兰13%，斯洛伐克8%，南欧6%，埃及6%，俄罗斯5%。
在捷克共和国，使用Epidat系统报告传染病。对报告的输入性病毒性肝炎病例进行的Epidat数据库分析是评估与出国旅行相关健康风险的重要起点。
