Abstract

Despite sophisticated intensive medicine, between one and three malaria-associated deaths occur annually in Switzerland. In this retrospective study, 33 deaths (25 men and 8 women) caused by falciparum malaria reported in Switzerland from 1988 to 2002 were analyzed. The case fatality ratio (CFR) for the falciparum infections for the 15-year period was 1.2%, with a peak of 2.2% in 1991. Sub-Saharan Africa was the source of all the imported fatal infections. Non-immune Europeans had a significantly higher case fatality ratio than the non-Europeans (1.7% versus 0.2%; P < 0.001). Careless use or non-use of prophylaxis, sometimes because of physicians giving unsatisfactory pre-travel advice, and initially missed diagnosis post-travel were factors that contributed to the development of severe infections leading to death. Travelers should be sensitized to the risk of malaria by well-informed general practitioners. Updated information is readily available (www.safetravel.ch). Regarding diagnosis and treatment, greater physician awareness of the disease is needed, and expert advice should be sought without hesitation. Rapid malaria tests may be a useful diagnostic adjunct in centers where microscopic expertise is lacking. Falciparum malaria in a non-immune patient is an emergency requiring immediate treatment.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
