[Imported diseases in Switzerland: development and perspectives]
1Schweizer Tropeninstitut, Basel.
Abstract:
During the last years, imported diseases have become more frequent in Switzerland. This is easily explained by the enormous increase of tourism to tropical and subtropical countries. Immigration from these countries has equally seen an important augmentation. The principal imported diseases are still malaria and gastrointestinal infections. Viral infections are rarely diagnosed, with the exception of hepatitis and HIV infection. The prevalence of sexually transmitted diseases is most certainly underestimated. The differential diagnosis of imported skin diseases is still difficult. Rare tropical diseases will probably become more frequent in the coming years as travellers leave more and more the traditional tourist paths. Practitioners have to look out for such problems, and continuous training programmes for them will have to take these new problems into account. Referral centres of infectious diseases should be established in all regions of Switzerland. High priority should be given to the prevention of imported diseases.
Insights
Imported diseases like malaria and gastrointestinal infections are increasing in Switzerland due to travel and immigration. Healthcare providers need updated training and referral centers to manage these growing public health challenges.
Area of Science:
- Tropical medicine
- Infectious disease epidemiology
- Public health
Context:
- Increased international travel and immigration to Switzerland have led to a rise in imported diseases.
- Traditional tourist routes are expanding, increasing exposure to rare tropical illnesses.
- Existing healthcare infrastructure may not be fully equipped to handle the growing prevalence of these conditions.
Purpose:
- To highlight the increasing incidence of imported diseases in Switzerland.
- To identify the primary types of imported diseases and risk factors.
- To recommend strategies for improved diagnosis, management, and prevention.
Summary:
- Malaria and gastrointestinal infections remain the most common imported diseases, while viral infections like hepatitis and HIV are also noted.
- Sexually transmitted diseases are likely underdiagnosed, and imported skin diseases present diagnostic challenges.
- An increase in rare tropical diseases is anticipated as travel patterns evolve.
Impact:
- Enhanced practitioner awareness and continuous training are crucial for managing imported diseases.
- Establishing regional infectious disease referral centers is recommended to improve patient care.
- Prioritizing the prevention of imported diseases is essential for public health in Switzerland.
