[Imported fever]

Abstract:
Fevers without distinguishing symptoms in persons who have visited tropical or subtropical areas is an increasing health problem in most western countries. The condition may be caused by several different microbes, but among cases diagnosed in Norway five infections dominate: falciparum malaria, vivax malaria, typhoid fever, paratyphoid fever, and dengue fever. In this article the authors give an overview of current microbes, and present diagnostic guidelines on how to handle cases of imported fevers in Norway. Primary measures should be taken against immediate life-threatening diseases, e.g. typhoid fever and falciparum malaria.
Insights
Imported fevers, such as malaria and typhoid fever, are a growing concern in western countries. This overview presents diagnostic guidelines for imported fevers, prioritizing immediate life-threatening conditions like typhoid fever and falciparum malaria.
Area of Science:
- Tropical infectious diseases
- Microbiology
- Public health
Context:
- Increasing incidence of fevers in individuals returning from tropical/subtropical regions.
- Common imported infections in Norway include falciparum malaria, vivax malaria, typhoid fever, paratyphoid fever, and dengue fever.
- Need for clear diagnostic protocols for imported febrile illnesses.
Purpose:
- To provide an overview of prevalent microbes causing imported fevers.
- To present diagnostic guidelines for managing imported fevers in Norway.
- To emphasize the importance of addressing life-threatening infections promptly.
Summary:
- Fevers in travelers from endemic areas pose a growing health challenge.
- Key infections include malaria, typhoid, paratyphoid, and dengue fevers.
- Diagnostic guidelines focus on identifying and managing critical conditions like typhoid and falciparum malaria.
Impact:
- Improved diagnostic strategies for imported fevers.
- Enhanced preparedness for tropical disease outbreaks in non-endemic settings.
- Timely intervention for severe infections, reducing morbidity and mortality.
