To define the risk of contracting malaria for travellers to malaria-endemic areas and to calculate the under-notification under the current notification system.
Retrospective epidemiological analysis.
Agricultural University Wageningen, The Netherlands.
Risks of contracting malaria were estimated by calculating the incidence per 100,000 travellers. This incidence was found using an estimated under-notification calculated on the basis of data from the "SIG Zorginformatie' (hospital cases) and the Medical Health Inspectorate (notified cases).
The average under-notification in the Netherlands was at least 59% in the period January 1988 to June 1993 inclusive and increased by 10% each year. Judging by this estimation at least 3170 travellers returned to the Netherlands with malaria in this period. The risk in Africa appeared to be decreasing. In Asia the malaria incidence increased slightly in recent years while no trend was found for America. The imported malaria was mainly caused by Plasmodium falciparum.
In order to improve the malaria notification system in the Netherlands a notification obligation for all microbiological laboratories should be introduced as almost all malaria is diagnosed there.
确定前往疟疾流行地区的旅行者感染疟疾的风险，并计算当前通报系统下的漏报情况。
回顾性流行病学分析。
荷兰瓦赫宁根农业大学。
通过计算每10万名旅行者中的发病率来估计感染疟疾的风险。该发病率是根据“西格医疗信息”（医院病例）和医疗卫生检查局（通报病例）的数据计算出的估计漏报率得出的。
1988年1月至1993年6月期间，荷兰的平均漏报率至少为59%，且每年增加10%。据此估计，在此期间至少有3170名感染疟疾的旅行者返回荷兰。非洲的风险似乎在降低。近年来亚洲的疟疾发病率略有上升，而美洲未发现趋势。输入性疟疾主要由恶性疟原虫引起。
为改进荷兰的疟疾通报系统，应规定所有微生物实验室有通报义务，因为几乎所有疟疾都是在这些实验室诊断出来的。
